Definitions
- the process used by different authors consists first of all in a propoxylation of the lignin by reacting the lignin with the propylene oxide in the presence of a catalyst and then reacting the product obtained with example of isocyanate.
- the lignin is in solid form. Because of this, it is difficult to engage it in the form of a homogeneous reaction medium. It also tends to generate deposits that can clog different components of an installation, such as for example reactors, pipes, valves, ducts, and others. For this reason, it is also difficult to manipulate on an industrial level.
- WO2008 / 123888 describes the synthesis of rheology agents for drilling muds.
- This fluid may comprise a modified lignin-based polymer.
- this product must be crushed at the end of the reaction. This solid is then incorporated into a two-phase emulsion.
- the present invention aims to propose a solution to solve all of the problems mentioned above.
- the present invention firstly relates to a method of manufacturing at least one grafted polyphenol comprising at least the following step:
- C3-C30 preferably C3-C20, more preferably C8-C20, more preferably still C8-C18, optionally comprising one or more saturated or unsaturated rings, said chain optionally being interrupted by one or more heteroatoms chosen; among the oxygen atom (O), the sulfur atom (S) and the nitrogen atom (N), preferably chosen from O and S, more preferably O;
- R2 is chosen from the hydrogen atom and a linear or branched, saturated or unsaturated C 1 -C 60 hydrocarbon-based chain, optionally comprising one or more saturated or unsaturated rings, said chain being optionally interrupted by one or more heteroatoms chosen from 1 oxygen atom (O), the sulfur atom (S) and the nitrogen atom (N), preferably chosen from O and S, more preferably O, the number of moles of said compound of formula ( I) being greater than or equal to the number of -OH functions present per mole of said polyphenol.
- O oxygen atom
- S sulfur atom
- N nitrogen atom
- the process according to the invention makes it possible to react a very large majority of the -OH functions, preferably all the -OH functions, present on a polyphenol with the compound of formula (I), so that said process makes it possible to lead to a polyphenol whose -OH functions, preferably all -OH functions, have reacted with the epoxide function of the compound of formula (I).
- the method according to the invention makes it possible to make available a very large majority of -OH functions, preferably all -OH functions, present on the polyphenol. Indeed, it turns out that the grafting of the compound of formula (I) on the hydroxyl functions of the polyphenol leads to the formation of a grafted polyphenol whose hydroxyl functions are further removed from the aromatic ring of the polymer structure, that is, more accessible and more responsive.
- the graft polyphenol obtained by the process according to the invention can also be considered as an extremely valuable reagent for an alkoxylation reaction, which may be called "later".
- liquid or viscous grafted polyphenol makes it possible to perform subsequent alkoxylations in good safety conditions, so that they can be easily implemented on an industrial scale.
- the operating conditions in terms of temperature and pressure are more easily controlled because the medium is in the form of a homogeneous liquid having a viscosity compatible with an industrial process, that is to say a viscosity generally ranging from , 7 Pa.s at 40 Pa.s.
- the exothermicity of the reaction can in particular be easily controlled.
- the subsequent alkoxylation process makes it possible to obtain an alkoxylated polyphenol in good yield and in quite reasonable reaction times compatible with industrial use.
- FIG. 1 is a 31 P NMR spectrum of an initial Kraft lignin, derivatized by a phosphorus reagent
- FIG. 2 is a 31 P NMR spectrum of a grafted polyphenol, and derivatized by a phosphorus reagent, that is to say the initial Kraft lignin after reaction according to step (a), then derivatized;
- hydrocarbon-based chain or "hydrocarbon-based radical” means a chain, or a radical, comprising one or more carbon atoms and one or more hydrogen atoms.
- the process according to the invention comprises a step (a) reacting, in the presence of at least one catalyst, at least one polyphenol with at least one compound of formula (I) below:
- the number of moles of said compound of formula (I) being greater than or equal to the number of -OH functions present per mole of said polyphenol.
- Said number of moles of said compound of formula (I) depends on the number of -OH functions present per mole of said polyphenol. This number of -OH functions present in one mole of said polyphenol is easily determined by those skilled in the art by applying the method described for example in the thesis entitled “Lignin-based Polyurethanes: Characterization, Synthesis and Applications “Borges Cateto, (2008), 57-66, or in the document” 2-Chloro-4,4,5,5-tetramethyl-1,3,2-dioxaphospholane, Reagent for the Accurate Determination of the Uncondensed and Condensed Phenolic Moieties in Lignins, Argyropoulos et al., (1995), J. Agr. Food. Chem., 43, 1543-1544.
- the grafted polyphenol from step (a) has an average molecular weight Mw ranging from 500 to 25,000, preferably from 500 to 20000, more preferably from 1000 to 20000, most preferably 1500 to 10000.
- the average molecular weight Mw can be easily determined by those skilled in the art by applying the method described for example in the document “Molarmass determination of lignins by size-exclusion chromatography: towards standardization of the method" Baumberger et al., Holzaba, 61, 459-468, (2007).
- the polyphenols used in the process according to the invention may be chosen from natural tannins, lignins and polyphenols other than tannins and lignins, preferably lignins.
- Kraft lignin is derived from the paper making process of the same name.
- Kraft lignin is a combination of three phenolic compounds, coumaryl alcohol, coniferyl alcohol and sinapyl alcohol.
- Nndulin AT TM marketed by Ingevity
- Kraft lignin marketed by Fibria or lignin marketed by Stora Enso can be used.
- the lignosulphonates differ structurally from the kraft lignin by the presence of sulphonic functions generally salified, which ensures them better solubility in water.
- Examples of lignosulphonates are lignosulphonates of the Borresperse TM, Ultrazine TM, Ufoxane TM or Vanisperse TM type from Borregaard.
- Organosolv lignins are obtained by chemical etching of woody plants, such as cereal straw, using various solvents, such as formic acid or acetic acid.
- various sources of lignins of the organosolv type there is Biolignin TM marketed by the CIMV company or that marketed by the company Fibria.
- the polyphenol used is lignin.
- Step (a) of the process according to the invention is carried out in the presence of at least one catalyst.
- the catalyst may be selected from alkali metal hydroxides, sodium or potassium alkoxides, and tertiary amines selected from trialkylamines and tetramethylguanidine, preferably selected from alkali metal hydroxides.
- the catalyst represents from 0.01 to 10% by weight, preferably from 1 to 6% by weight relative to the weight of polyphenol.
- R6 denotes a hydrogen atom or a C1-C2 alkyl radical.
- This method makes it possible in particular to make the functions more accessible.
- the viscosity of the grafted polyphenol is lower, that is to say that said polyphenol is even more easily manipulated, especially the polyphenol from step (a).
- Step (b) is preferably carried out in the presence of a catalyst. This may be identical or different from the catalyst used in step a). If the catalyst of step b) is identical to the catalyst of step a), no additional catalyst is added, or a complementary amount of catalyst is added.
- the catalyst used during step (b) may be chosen from alkali metal hydroxides, sodium or potassium alkoxides, and tertiary amines chosen from trialkylamines and tetramethylguanidine, preferably chosen from alkali metal hydroxides.
- said catalyst is selected from lithium hydroxide, sodium hydroxide, potassium hydroxide and cesium hydroxide.
- the catalyst used in step (b) represents from 0.01 to 10% by weight, preferably from 1 to 6% by weight relative to the weight of grafted polyphenol from step (a). Reaction conditions
- the duration of step (b) varies from a few minutes to several hours, preferably from 5 minutes to 24 hours, more preferably from 10 minutes to 12 hours, even more preferably from 10 minutes to 10 hours.
- residual alkoxylating agent means an alkoxylating agent which has not reacted.
- the method of manufacturing a grafted polyphenol or an alkoxylated polyphenol according to the invention may be implemented batchwise or semi-continuously.
- the initial lignin is impregnated with an aqueous catalyst solution.
- the lignin is dried and added to a compound of formula (I) in a stirred reactor to obtain a graft polyphenol from step (a).
- an agent of formula (V) is added, and reacts with the grafted polyphenol from step (a).
- the alkoxylated polyphenol obtained at the end of step (b) is directly recovered from the reactor, the reaction medium preferably containing no solvent.
- the subject of the invention is also a grafted polyphenol obtainable by the method of manufacturing a grafted polyphenol according to the invention, and also an alkoxylated polyphenol obtainable by the process for the manufacture of an alkoxylated polyphenol according to the invention.
- the invention also relates to the alkoxylated polyphenol as defined above having a viscosity ranging from 0.7 Pa.s to 40 Pa.s, preferably from 0.7 Pa.s to 30 Pa.s. measured at 40 ° C.
- the grafted polyphenol according to the present invention is an extremely valuable reagent for "subsequent" alkoxylation reactions because of the more accessible hydroxyl functional groups.
- the invention also relates to the use of the graft polyphenol as defined above as a solvent for polyphenols, as well as the use of the alkoxylated polyphenol as defined above as a solvent for polyphenols. According to yet another aspect, the invention relates to the use of the graft polyphenol as defined above as a solvent in alkoxylation processes of polyphenols, as well as on the use of the alkoxylated polyphenol such as defined above as a solvent in alkoxylation processes of polyphenols.
- the grafted polyphenol and the alkoxylated polyphenol as defined above have the advantage of behaving like polyphenols while being liquids (more or less viscous homogeneous), said ungrafted polyphenols and / or not alkoxylates being generally, and most often, solid at ambient temperature and pressure.
- Said graft polyphenol and said alkoxylated polyphenol may thus constitute a solvent for said non-grafted and / or non-alkoxylated polyphenols solid at ambient temperature and pressure as well as for alkoxylation reactions, and thus allow these reactions on an industrial scale.
- the invention relates to the use of graft polyphenol as defined above for producing polyurethanes, polyesters, nonionic or cationic surfactants, biosourced precursors of carbon fiber.
- the invention also relates to the use of the alkoxylated polyphenol as defined above for producing polyurethanes, polyesters, nonionic or cationic surfactants, biosourced precursors of carbon fiber. It is also conceivable to use the grafted polyphenol or the alkoxylated polyphenol as defined above to manufacture other compounds.
- FIG. 1 is a 31 P NMR spectrum of the initial Kraft lignin, derivatized by 2-chloro-4,4,5,5-tetramethyl-1,3,2-dioxaphospholane for the purpose of the analysis.
- Peak A denotes aliphatic -OH functions
- peak B denotes phenolic -OH functions
- peak C denotes carboxylic acid -OH functions.
- Examples 6, 7 and 8 are carried out in a reactor of 500 cm 3 .
- Examples 9 to 11 were made with an epoxy having an alkyl chain of C16 (Vikolox ® C16) according to Table 2 below.
- Examples 15-21 were carried out with an aromatic epoxy according to formula (IV) (Cardolite ® NC-513), according to Table 4 below.
- Ratio (number of moles of Cardolite ® NC-513) / (number of OH functions per mole of Indulin AT TM lignin)
- Examples 20 and 21 are made in a 300 cm 3 reactor.
- FIG. 2 is a 31 P NMR spectrum of a grafted polyphenol obtained at the end of step (a), more specifically the graft polyphenol as obtained according to example 20, derivatized by 2- chloro-4,4,5,5-tetramethyl-1,3,2-dioxaphospholane for the purpose of the analysis. It is found that peaks B and C have disappeared, indicating that all the phenolic -OH functional groups and carboxylic acid functional groups have reacted with the compound of formula (I) (epoxide Cardolite ® NC-513) to give an overwhelmingly secondary alcohol whose peak is in the zone of aliphatic -OH functions. It is also found that all aliphatic -OH functions of different environment in the initial lignin (corresponding to peak A in FIG. 1) react with the compound of formula (I) to lead to a secondary -OH function of the same type than the other functions. This explains why the signals are no longer in the form of a solid as is the case for the initial lignin.
- FIG. 3 is a 31 P NMR spectrum of the product obtained after step (b), derivatized by 2-chloro-4,4,5,5-tetramethyl-1,3,2-dioxaphospholane for need analysis. It can be seen that only the characteristic peak of the aliphatic secondary -OH function is present.
