Definitions
- the invention relates to mixtures of phthalic acid esters with a viscosity which can be set via the contributions of the individual isomeric alcohols, from which the phthalic acid esters can be prepared, and their use.
- Phthalic acid esters are widely used as plasticizers for plastics such as PVC.
- Plasticizers can be defined as substances that give a material, in particular plastics, increased flexibility, softness and processability (Alan S. Wilson, Plasticizers, The Institute of Materials, 1995, ISBN 0 901 716 76 6, p. 1). The plasticization of PVC is particularly, but not exclusively, of particular importance.
- esters from polyvalent carboxylic acids and monoalcohols are most commonly used.
- polyvalent aromatic carboxylic acids or their anhydrides used are phthalic acid and isophthalic acid, trimellitic acid, pyromellitic acid or terephthalic acid.
- Inorganic acids are also used, the best known example being the esters of phosphoric acid.
- these carboxylic acids or their anhydrides in the case of the phosphoric acid esters also the acid chlorides such as POCl, are reacted with monoalcohols such as ethanol, butanol, isobutanol, n- and iso-amyl alcohols, heptanol, 2-ethylhexanol, 2-propylheptanol.
- monoalcohols such as ethanol, butanol, isobutanol, n- and iso-amyl alcohols, heptanol, 2-ethylhexanol, 2-propylheptanol.
- Isomer mixtures which are obtained by oligomerizing olefins having 3 to 5 carbon atoms with subsequent hydroformylation and hydrogenation of the aldehydes obtained are preferably also used as higher alcohols.
- isoheptanol isooctanol, isononanol, isodecanol, isotridecanol.
- linear so-called alpha-olefins can also be obtained, which give a mixture of linear and little branched alcohols in the hydroformylation.
- alcohols produced in this way are nonanol and undecanol and their mixtures.
- Straight-chain alcohols can be obtained from fat chemistry, but also through synthetic construction from ethylene, e.g. so-called Ziegler alcohols.
- cyclic alcohols such as cyclohexanol, benzyl alcohol, phenols, cresols, xylenes, which have found industrial use.
- polyvalent alcohols can also be converted into plasticizers using monocarboxylic acids.
- polyhydric alcohols are neopentyl glycol, trimethylol propane, pentaerythritol, di-pentaerythritol, ethylene glycol and its oligomers di-, tri- and tetraethylene glycol, glycerol, butanediol, hexanediol and so on.
- Sugar alcohols have also been used for this purpose.
- the analogous compounds to the alcohols mentioned above are used as carboxylic acids, that is to say carboxylic acids in the range from 2 to about 13 carbon atoms.
- Examples are acetic acid in triacetin, butyric acids, valeric acids, heptanoic and nonanoic acid and isomer mixtures such as isoheptanoic, isooctanoic, isononanoic, isodecanoic and isotridecanoic acid.
- esters of monoalcohols and monocarboxylic acids are also used as plasticizers in special cases if their boiling point is high enough, such as stearic acid or lauric acid esters.
- the aim is generally to produce compounds that have sufficient polarity to serve as good plasticizers, that have a high molar mass in order to be as volatile as possible and to show little migration in the material, but are still fluid and one in comparison to Molar mass have low viscosity, so that they are easy to process.
- esters can be tailored for almost every application, although there are of course limits to the effort required and the associated costs, as well as the availability of the raw materials. Many of the possible combinations listed have therefore disappeared from the market today, have found only limited importance in niche applications or are only of academic importance. Under certain circumstances, however, this can change quickly if new processes make raw materials inexpensively accessible, replacement materials for previously common products have to be found through changed environmental awareness, or new technical requirements force new solutions.
- Isononanol is produced by hydroformylation of octenes, which in turn are produced in different ways.
- Technical C 4 streams which initially contain all the isomeric C 4 olefins in addition to the saturated butanes and possibly impurities such as C 3 and C 5 olefins and acetylenic compounds, are generally used as the raw material.
- Butadiene is first obtained as a valuable substance by extractive distillation, for example with NMP (N-methyl-pyrrolidone). Alternatively, the butadiene can also be converted into 1- and 2-butene by selective hydrogenation, such as. B. in the SHP-CB process of OXENO GmbH.
- the isobutene is usually removed in a second process step by reaction with methanol under acid catalysis, for example with acidic ion exchangers.
- methanol methyl t-butyl ether
- raffinate II methyl t-butyl ether
- methanol other alcohols such as ethanol can also be used.
- ethyl t-butyl ether the ETBE
- isobutene can also be removed selectively with water instead of alcohols to form the t-butyl alcohol TBA, which is also an important technically used compound
- a C 4 stream remains, which essentially contains only 1- and 2-butene in addition to the saturated butanes, the so-called “raffinate II”.
- 1-butene can optionally be obtained from the raffinate II as a valuable substance, for example as a comonomer for polyolefins, and likewise isobutane, which is used as a propellant.
- a C4 stream depleted in 1-butene, the raffinate III, is then obtained.
- Both raffinate II and raffinate III can be used as raw materials for the oligomerization.
- the older oligomerization processes work with acidic catalysts such as phosphoric acid on supports or acidic zeolites (process variant A). This gives octenes which essentially contain dimethylhexenes.
- Newer processes such as the DIMERSOL process work with soluble Ni complex catalysts. Here octene mixtures with high proportions of 3- and 5-methylheptenes are obtained in addition to n-octenes and dimethylhexenes (process variant B).
- the most modern processes use the high selectivity of special supported Ni catalysts, the OCTOL process from OXENO GmbH is well known.
- octenes Another way to get octenes is to oligomerize isobutene.
- the main product is a mixture of 2,4,4-trimethylpentene-1 and 2,4,4-trimethylpentene-2.
- the oligomerization of ethylene using Ziegler catalysis or using the SHOP process is also a route to higher olefins, whereby linear terminal olefins are formed with a broad C number distribution.
- a C 8 cut can be obtained from this. Such cuts are also available from Fischer-Tropsch processes.
- the opportunity is occasionally taken from flows of naphtha Separate hydrocarbons of a suitable C number. These contain predominantly saturated alkanes, which are converted into olefins by dehydrogenation.
- hydroformylation i.e. the conversion of the olefins with carbon monoxide and hydrogen, the so-called synthesis gas, to form aldehydes.
- Hydroformylation with hydridocobalt carbonyl as a catalyst is common at 200 to 300 bar and 170 to 190 ° C (co-high pressure process Co-HD).
- Co-HD co-high pressure process
- cocatalysts modified with alkylphosphines is also carried out industrially (co-ligand).
- a method is known which works with rhodium instead of cobalt as a catalyst at 100 to 300 bar and 120 to 130 ° C (Rh-HD).
- the three processes differ significantly in the isomer composition of the products.
- approx. 50% linear n-nonanol are obtained in addition to the internally oxidized isomers (n / i ⁇ 1)
- Rh-HD oxidation approx. 20% (n / i ⁇ 0.25) is obtained in addition to the oxidation of the branched olefins.
- the isomer composition of the plasticizer alcohols produced can thus vary within wide limits. However, it is known that the physical and application properties of plasticizers are strongly dependent on the structure.
- the viscosity of the phthalates measured at 20 ° C., is given below as an example of a physical property.
- phthalates of isononanol can have viscosities in the range from 50 to 60 mPa * s when using linear olefins, but DINP types with 160 to 170 mPa * s when using codibutylene are also known.
- DINP types based on polygas octenes have viscosities in the range of 90 to 110 mPa * s.
- the application properties that are necessary for an ester to perform its function are extremely diverse.
- the viscosity When used as a lubricant, for example, the viscosity, the dependence of the viscosity on the temperature, the dropping point and much more play a role.
- the viscosity of the plasticizer In the case of plasticizers, in addition to the flexibilizing effect, in particular at low temperatures, the viscosity of the plasticizer is also, however Electrical properties even when used in cable jackets. All of these properties depend on the structure and thus on the isomer composition of the substances used.
- the performance properties depend on the structure of the phthalate, this partly depends on the structure of the alcohol and, in turn, partly on the structure of the underlying olefin.
- An additional complication is that these compounds are produced as a mixture of isomers. It would therefore be desirable to change or assemble the mixture composition to obtain a mixture with predefined properties.
- the viscosity of lubricants may only vary within narrow limits in order to maintain the desired viscosity class.
- plasticizers for example, the plasticizing effect must remain constant in order not to force the processor of the plasticizer to constantly adjust the formulation, or the electrical resistance must not be undercut. An ongoing production control by means of application tests is not possible at all, as explained above, quite apart from the costs that this would cause.
- the viscosity of the phthalate esters depends on the structure or on the isomer composition of the alcohols used for the esterification. This correlates with application-related variables such as the cold-flexibilizing effect and electrical resistance. If there are enough measurements, this can be described by theoretically sound or simple empirical equations.
- the viscosity of mixtures of isomeric compounds can be easily Mixing rule can be estimated from the individual components, it applies according to VDI-Wärmeafias, NDI Verlag, seventh extended edition, 194, section Da 30
- the essential composition can be stated as follows: n-nonanol, 2-methyl-octanol, 2-ethyl-heptanol, 2-propyl-hexanol, 4-methyl-octanol, 3-ethyl heptanol, 6-methyl-octanol, 2,3-dimethyl-heptanol, 2-propyl-3-methyl-pentanol, 2-ethyl-4-methyl-hexanol, 2,5-dimethyl-heptanol, 4,5-dimethyl heptanol, 2,3,4-trimethyl-hexanol and 2-ethyl-3-methyl-hexanol.
- a single compound is only formed if the alcohol used consists of a single isomer.
- the esterification of Phthalic acid with n-nonanol di-n-nonyl phthalate If, on the other hand, the alcohol used for the esterification consists of several isomers, phthalates in which the two alkyl radicals are the same or different can arise, for example, in the esterification of phthalic acid.
- 14 phthalates in which the alkyl groups are the same and 91 (14 * 13/2) phthalates in which the two alkyl groups are different can be formed.
- a total of 105 different phthalates can be formed without taking stereoisomers into account.
- the present invention therefore relates to mixtures of isomeric dialkyl phthalates with a certain viscosity, prepared by esterifying phthalic acid or phthalic anhydride with a mixture of isomeric alkyl alcohols and with a certain number of carbon atoms, characterized in that the viscosity of the phthalic ester mixture is determined by the composition of the isomeric alkyl alcohols and whose viscosity index is set according to formula I.
- the viscosities of the mixtures depend on the number of carbon atoms in the isomeric alkyl alcohols used for the esterification. The following viscosities or preferred ranges are according to the invention.
- Xj 2 molar fraction of an isomer of the alcohol mixture 2, which is in the saponification of the
- a, b and c are the relative proportions of the three components in the total mixture.
- the present invention therefore furthermore relates to mixtures of isomeric dialkyl phthalates with a certain viscosity, prepared by mixing isomerically pure dialkyl phthalates and / or dialkyl phthalates, the alkyl esters having the same C number and a C number corresponding to the viscosity, characterized in that Mixture of the isomeric phthalic dialkyl esters has a viscosity and composition according to formula IV (equations II and III are special cases of the generally applicable equation IV).
- ⁇ viscosity of the phthalic dialkyl ester mixture after mixing the components
- y mole fraction of a specific isomer i in the alcohol mixture j which is used in the
- Equations II to IN can also be used to calculate the proportions of the mixture if an alcohol mixture, made from two or more alcohol mixtures (components) with different isomer compositions (type of isomers and proportion), is to be provided for the production of a phthalate mixture with a given viscosity.
- the present invention furthermore relates to processes for the preparation of the mixtures of isomeric phthalic dialkyl esters mentioned with the viscosities mentioned by mixing the phthalic acid esters or the alcohols before esterification.
- Isononyl phthalates according to the invention prepared from alkyl alcohols having 9 carbon atoms, can be obtained by using a mixture of isomeric alkyl alcohols, a mixture of anolonanols, which has been prepared by mixing an isomerically pure ⁇ onanol or a ⁇ onanol mixture with n- ⁇ onanol.
- a mixture of isomeric alkyl alcohols a mixture of alkonanols which has been prepared by mixing an isomerically pure ⁇ onanol or a alsonanol mixture with 3,5,5-trimethylhexanol.
- auxiliary components By appropriately mixing the auxiliary components, all products can be manufactured whose viscosity lies between these limits.
- DI ⁇ P qualities with viscosities in the range of ⁇ 45 to ⁇ 110 mPa * s can be set, the first case resulting in a product with a good cold-flexibilizing effect which second case, a product with less good cold fiexibilizing effect, but with increased electrical resistance.
- the phthalic ester mixtures according to the invention can be used very flexibly due to the easily adjustable viscosity and can be used as plasticizers for plastics, in particular PVC, as hydraulic fluids, as lubricants or as lubricant components become.
- the procedure is to summarize the unknown remainder and treat it as a dummy component. If this unknown remainder is not too large, for example less than 10% or better less than 5%, the error is not impermissibly large. For example, a range of +/- 2 mPa * s for the end product includes many measurements with unknown residues of a few%.
- isomers are compounds of the same empirical formula but different structures.
- Isomer-pure means that the ester or the alcohol consists only of compounds of one isomer (stereoisomers are regarded as an isomer in this context), customary and / or technical impurities of other isomers not being taken into account.
- the control can be carried out by a process gas chromatograph, coupled with automatic calculation of the expected viscosity of the plasticizer.
- olefins All synthetic possibilities for the production of olefins can be used in order to obtain different starting olefins.
- the olefins are then hydroformylated by different processes, for example with high pressure, high pressure or with ligand-modified Rh and co-catalysts. This gives a further differentiation of the isomer composition even with the same olefin used. Hydrogenation then gives the desired alcohols, in the example isononanols, with completely different isomer compositions. Further differentiation can be achieved by careful distillation to obtain isomer sections with an unnatural isomer distribution. Of course, other synthetic methods for the production of alcohols and aldehydes can also be used.
- Excipient such. B. 1-octene or a slightly branched octene mixture, are provided to lower the viscosity of the plasticizer to be produced thereafter, and the addition of diisobutene or a strongly branched octene mixture to increase the viscosity analogously.
- the isomer distribution of the oxidation process that occurs during a hydroformylation step is known from the ongoing analysis and can be converted to the required dosage of the auxiliary.
- the composition of the isomer distribution changed by the metering in can thus also be calculated, and thus also the calculation of the expected viscosity of the plasticizer to be produced.
- the composition is determined from the different alcohol mixtures. It is helpful, but not essential, to understand the structure of each isomer knows. On the other hand, it is important that the isomers are distinguishable and their relationship to one another can be determined. Since the analysis of the isomer composition is mostly carried out by gas chromatography, the isomers can be distinguished by their retention indices, if possible determined on two different columns.
- nonanol mixtures are carried out as follows:
- the retention indices (R;) of the nonanol isomers with retention times (RT) between those of n-octanol and n-nonanol are calculated using the following formula:
- Carrier gas Helium gas flow: 1.5 ml / min Start temperature: 60 ° C End temperature: 220 ° C heating rate. 2 ° C / min Table 1 lists the analysis of an isononanol mixture. As analysis of some selected mixtures showed, area% can be set equal to weight percentages with sufficient accuracy.
- a and B diastereomers that can be distinguished by gas chromatography on a column with non-optically active filling material.
- esters are then produced from the various alcohol mixtures and important application data, especially the viscosity, are determined. If, on the other hand, phthalate mixtures are present, their viscosity can be determined and the underlying alcohol mixture obtained and saponified from them and analyzed. One then applies the mixing rule for the viscosity, but instead of the inaccessible portions of the ester isomers, the much simpler and easy to determine isomer distribution of the alcohols is used and the data sets are subjected to a non-linear regression calculation. The fictitious viscosity contributions of the individual components are then obtained as an estimate.
- a fictitious viscosity contribution (viscosity index) is made for each isononoisomer using the program (DataFit, OAKDALE Engineering, Version 5.1, http: Wwww.oakdaleengr.com) (Table 2f, last column). This procedure can also be applied to other nonyl phthalate mixtures based on other or additional nonanol isomers.
- the values for the fictitious viscosity contributions shown in table 2f, last column, can be specified with increasing number of data sets. Table 2a
- Example 2 Process variants for the preparation of diisononyl phthalate (DI ⁇ P) by esterification of phthalic anhydride with a mixture of isomeric anolonanols:
- the DI ⁇ P to be produced should have a viscosity of approx. 78 mPa * s with the limit values 75 - 80 mPa * s.
- n-anolonanol contributes to the total viscosity of approx. 43 mPa * s, 3,3,5-trimethylhexanol of approx. 111 mPa * s.
- n-Nonanol is commercially available, but you can also hydroformylate commercially available 1-octene or cheaper internal n-octenes to form an isomer mixture with a low viscosity contribution, it only has to be significantly below the selected limit value.
- 3,5,5-Trimethyl-hexanol is also commercially available and can also be easily produced by hydroformylation of diisobutene with subsequent hydrogenation, which in turn is accessible again by oligomerization of isobutene and is a commercial product. Finally, mixtures of isomers with low and high viscosity contributions can be kept.
- EP 1 029 839 shows how an isononanol is obtained from an octene mixture and gives a viscosity of 77 mPa * s in DINP. It also describes that it is possible to separate the octene mixture into two fractions with a lower and higher degree of branching. The less branched fraction after oxygenation, hydrogenation to the alcohols and subsequent esterification with phthalic anhydride gives a DINP with approx. 68 mPa * s, the higher branched fraction a DINP with approx. 103 mPa * s. It is therefore sufficient for the process described to hold these two alcohol fractions, which come from the same raw material as the isononanol produced.
- the following examples describe the relationship between DINP mixtures with different isomer compositions and their voscosities and application properties.
- the ester was then heated to 180 ° C. under vacuum.
- demineralized water (8% based on the weight of crude ester) was added dropwise via a dip tube. After this steam distillation had ended, a vacuum of 30 mbar was applied for 30 minutes at 180 ° C. to remove traces of water.
- the product now cooled to 80 ° C. under vacuum and was then filtered through a suction filter with filter paper and filter aid.
- T g glass transition temperature
- DDK Dynamic Differential Calorimetry
- TAA Torsional Braid Analysis
- TSA torsional vibration analysis
- the corresponding diisononyl phthalates were prepared from various nonanol mixtures and both the viscosity and the glass transition temperature of the plasticizer (phthalate) were determined. The relevant data are listed in the following table.
- 80 g were cut out, placed in a template 220 * 220 * 1 mm and in a hydraulic hand press (60 t) from Werner & Pfleiderer as follows pressed: The temperature was set to 170 ° C and the template with rolled skin was initially 2 min. at 50 bar, then 1 min. at 100 bar and finally again 2 min. pressed at 180 bar. The pressure was then increased to 200 bar and cooled to room temperature at this pressure.
- Examples 3-5 demonstrate that the softening effect of DINP correlates with its viscosity, which is determined by the isomer composition of the underlying nonanol mixture.
- Example 6 Setting DINP to setpoints, e.g. 70, 80, 90 mPa * s by mixing
- Isononanol was mixed with n-nonanol or 3,5,5-trimethylhexanol in the ratio given in the table and, as described above, converted to the corresponding phthalates.
