Definitions
- the invention relates to a process for the preparation of substituted esters of (meth) acrylic acid which have several hydroxyl groups in the ester group.
- Beinert, Hild and Rempp (Die Makromolekulare Chemie, 175, 2069 - 2077 (1974)) describe the preparation of (2,2-dimethyl-1, 3-dioxolan-4-yl) methyl methacrylate by reacting a mixture of methacrylic acid and thionyl chloride contains in a solvent mixture of hexamethylene phosphoric acid triamide (HMPT) and diethyl ether with 2,3-0-isopropylidene glycerol.
- HMPT hexamethylene phosphoric acid triamide
- diethyl ether diethyl ether with 2,3-0-isopropylidene glycerol.
- the methacrylate obtained is polymerized anionically.
- the polymer is converted to poly (2,3-dihydroxypropyl methacrylate).
- the monomer is produced at -5 ° C to 15 ° C in a toxicologically harmful solvent. This method cannot be used in industrial technology due to the toxicological problems.
- WO 00/63149 (Hydron Ltd.) describes a method for producing a polymerizable diol by reacting a protected glycerol derivative of methacrylic acid with an immobilized acid in the form of an acidic ion exchanger. The resulting acetone is blown out of the reaction system with air. (2,2-Dimethyl-1, 3-dioxolan-4-yl) methyl methacrylate, deionized water and the washed cation exchanger are placed in the reaction vessel. An air stream is then passed through the mixture for 48 hours, which ensures that the reaction mixture is thoroughly mixed.
- the ion exchanger is filtered off and excess water is discharged through a stream of dried air.
- WO00 / 63150 also describes a process for the preparation of a polymerizable diol by the ion-exchange-catalyzed reaction of a protected glycerol derivative of methacrylic acid with the elimination of acetone.
- the methacrylic acid which is inevitably formed as a by-product is captured in a second step using a basic ion exchanger.
- This method also has the following disadvantages:
- GMMA glycerol monomethacrylate
- the increased thermal stress also creates crosslinking compounds in the monomer, which polymerize in the monomer and lead to an undesirable increase in viscosity that does not make the monomer salable.
- crosslinkers in the monomer lead to changes in the properties of the polymer, which are also undesirable.
- the increased thermal load during the manufacturing process must therefore be kept as low as possible.
- A (CH 2 ), where m can have the values 0 or 1,
- R 2 "6 may be the same or different and assume the meanings OH, H, aliphatic or aromatic hydrocarbon, such as methyl, ethyl, propyl, isopropyl, butyl, isobutyl, tertiary butyl, pentyl, hexyl, cyclopentyl, cyclohexyl, methylcyclohexyl , Isobornyl, heptyl, octyl, substituted hydrocarbon radicals, such as Hydroxyethyl, 2- (N, N-dimethylamino) ethyl, 2- (N, N-dimethylamino) propyl, 2-hydroxypropyl, 2-hydroxyethyl, 2-ethylhexyl, iso-octyl, n can have the values 0, 1 or 2 accept,
- R 1 , R 2 , R 3 , R 4 , R 5 , R 6 , A, m and n have the meanings given above and R 7 and R 8 can be the same or different and can have the meanings methyl, ethyl or propyl , reacted with water in small amounts on an acidic ion exchanger in a fixed bed and the resulting compound III
- a favorable ratio of compound II to water is between 1: 1 and 1: 3. Very good results are achieved with a ratio of 1: 1, 1 and 1: 2.5.
- a special embodiment of the invention provides use at a ratio of 1: 1, 2 to 1: 2.
- a ratio of 1: 1, 5 proves to be particularly useful.
- the water content in the ion exchanger is included in all of the above.
- a tocopherol compound is preferably used for the storage and color stabilization of ethylenically unsaturated monomers.
- the tocopherol compounds which can be used in the context of the invention are chroman-6-oles (3,4-dihydro-2H-1-benzopyran-6-ole) substituted in the 2-position with a 4,8,12-trimethyltridecyl radical.
- To the present invention is preferably usable tocopherols to alpha-tocopherol, beta-tocopherol, gamma-tocopherol, delta-tocopherol, and eta tocopherol zeta2-tocopherol, all of the aforementioned compounds each belonging to the (2 R, 4 'R, 8' R) - Form, as well as alpha-tocopherol in the (aÜ-rac) form.
- Alpha- tocopherol are preferred in the (2 R, 4 'R, 8'R) -form (common name: RRR-alpha-tocopherol) as well as the synthetic racemic alpha-tocopherol (all-rac-alpha-tocopherol). Of these, the latter is particularly interesting due to the relatively low price.
- the amount of tocopherol compound which can be used for the storage and color stabilization of stabilized monomers can vary over a wide range depending on the monomer and the desired efficiency. For many areas of application, quantities of up to 1000 ppm, based on the monomer mass, are sufficient. Very small additions of 10 ppm are often sufficient to achieve a noticeable improvement in storage and color stabilization. If you use less than 10 ppm, however, a significant storage and color stabilization is generally not noticeable. A favorable range for the amount to be added is therefore between 10 and 1000 ppm of tocopherol compound based on the Monomer mass. Very good results are achieved in the range of 50 to 800 ppm. A particular embodiment of the invention provides for use in an amount of 100 to 600 ppm. About 500 ppm of tocopherol compound are very particularly advantageously used.
- the notation (meth) acrylic includes methacrylic, acrylic and mixtures of both.
- IPGMA isopropylidene glycerol methacrylate
- GMMA glycerol monomethacrylate
- the bottom (4) of a separation column (3) is filled with 500 g IPGMA, which is stabilized with hydroquinone monomethyl ether.
- Basic stabilization is the stabilization of monomers or monomer mixtures with hydroquinones, such as, for example, hydroquinone monomethyl ether, 4-methyl-2,6-di-tert-butylphenol, 2,4-dimethyl-6-tert-butylphenol, which is generally customary in (meth) acrylate chemistry, Phenothiazine, N-nitrosophenylhydroxylamine, diethylhydroxylamine, 2,6-di-tert-butyl-alpha- (dimethylamino) -p-cresol or 4-hydroxy-2,2,6,6-tetramethylpiperidin-1 -oxyl (rad.) (eg TEMPOL®) or from mixtures of the aforementioned compounds.
- hydroquinones such as, for example, hydroquinone monomethyl ether, 4-methyl-2,6-di-tert-butylphenol, 2,4-dimethyl-6-tert-butylphenol, which is generally customary in (meth) acrylate
- the amount of stabilizer used is, for example, 35 ppm for each individual substance.
- the basic stabilization is added before the reaction. In the event that the monomers are mixed with the basic stabilization described above, the amount of tocopherol added as a storage stabilizer after the reaction is 10-1000 ppm, based on the amount of monomer. Without basic stabilization of the monomers, the amount of tocopherol added as a storage stabilizer after the reaction is 100-600 ppm.
- Preliminary reaction At the start of the experiment, the sump contents are placed under ambient pressure with the aid of a gear pump from above onto a tempered (40 ° C) water-moist ion exchanger fixed bed (e.g. from Dow Chemical, type: Dowex M-31) (1, 2) pumped. The water in the ion exchanger reacts with IPGMA to form GMMA and acetone. The reaction mixture then passes through a separation column - acetone is distilled out of the reaction mixture (6) - back into the sump, where it is pumped again to the fixed bed (recycle mode).
- a gear pump from above onto a tempered (40 ° C) water-moist ion exchanger fixed bed (e.g. from Dow Chemical, type: Dowex M-31) (1, 2) pumped.
- the water in the ion exchanger reacts with IPGMA to form GMMA and acetone.
- the reaction mixture then passes through a separation column - acetone is distilled out of the reaction mixture (6)
- Post-reaction The pressure is then gradually reduced to approx. 20 mbar in order to remove residual amounts of acetone and excess water. After a certain time interval (approx. 2 h), the plant is shut down and the finished reaction product from the sump and the fixed bed is discharged.
- the table shows the results of the turbidity measurement.
- the measuring device corresponds to the standard EN 270 27 (ISO 7027).
- the Formazin Standard is defined in the 13th edition (1971) Standard Methods of the Examination of Water and Wastewater, published by AWWA (American Waterworks Association).
- the sample to be measured is filled into the measuring cell. This is then rubbed off with a lint-free cloth and a thin film of silicone oil is applied on the outside. After inserting the filter module into the measuring device, the cuvette is inserted and the turbidity value is determined.
