Definitions
- the invention relates to a process for the preparation of oxetane group-containing methacrylates with high purity and minimal increase in color during production and their uses.
- (Meth) acrylates have a wide variety of applications.
- (Meth) acrylates are monomers which can be reacted in polymerization reactions, for example, to polymethacrylates. But (meth) acrylate polymers can also be used as a binder or additive in paints, coatings, coatings, etc.
- JP 200063371 describes the synthesis of trimethylolpropane oxetane methacrylate (3-methacryloxymethyl-3-ethyloxetane), including monomers which contain a spacer. This spacer is z. B. together from alkoxylates, including triethylene glycol.
- alkoxylates including triethylene glycol.
- higher degrees of ethoxylation of the trimethylolpropane oxetane are of interest for this invention since alcohols with n> 3 and a distribution fall below the polymer state and thus also the corresponding methacrylates.
- the preparation proceeds in the presence of basic catalysts, alkali metal and tin compounds. In these catalysts, a long reaction time is observed, and in the case of trimethylolpropane oxetane methacrylate, distillation is necessary to achieve high purity.
- J. Polymer Science: Part A: Polymer Chemistry, Vol. 41, pp. 469-475 (2003) and EP 867443 describe the preparation of 3- (meth) acryloxymethyl-3-ethyloxetane via (meth) acryloyl chloride.
- JP 47025342 describes the synthesis of trimethylolpropane oxetane methacrylate starting from sodium methacrylate and 3-ethyl-3-chloromethyloxetane in the presence of an amine catalyst. Again, the yield is low.
- Polymer Preprints 2004, 45 (2), p. 24 describes the preparation of ethoxylated trimethylolpropane oxetane acrylate by titanate catalysis.
- a color-causing stabilizer is used, as is an entrainer.
- the product is extracted for cleaning in an additional step with a water-ethanol mixture.
- the comparative example deals with a modified process by means of titanate catalysis. Elaborate work-up steps negatively affect the cost-effectiveness of the process.
- the object of the invention was to produce oxetane group-containing (meth) acrylates in high purity and with high yields.
- the object was achieved by a process for the preparation of oxetane group-containing methacrylates, characterized in that a zirconium catalyst is used and then residual monomers are removed by distillation from the mixture.
- the notation (meth) acrylate as used herein means both methacrylate, e.g. Methyl methacrylate, ethyl methacrylate, etc., as well as acrylate, e.g. Methyl acrylate, ethyl acrylate, etc., as well as mixtures of both.
- the catalyst used is zirconium compounds. Particularly preferred is zirconium (IV) acetylacetonate.
- the amount of catalyst is 0.01 to 5% based on the amount of the alcohol.
- Oxetane group-containing alcohols may be monosubstituted or polysubstituted and have one or more alcoholic groups. Particular preference is given to using ethoxylated trimethylopropane oxetane.
- (meth) acrylates all methacrylates such as methyl methacrylate, ethyl methacrylate, etc. can be used. But also acrylates can be used, such as methyl acrylate, ethyl acrylate, etc., as well as their mixtures. Particularly preferred is methyl methacrylate.
- the reaction is preferably carried out in a column.
- the starting materials are initially charged and for dehydration of the reaction mixture, the head temperature of the column is adjusted according to the monomer-water azeotrope used. For example, it is about 100 ° C. in the case of methyl methacrylate.
- the catalyst and the amount of (meth) acrylate corresponding to the distilled off water monomer azeotrope are added and then the reaction mixture is reheated.
- the resulting azeotrope of (meth) acrylate and its underlying alcohol is separated.
- the temperature is further increased and the reaction is completed when the column head is closed.
- the catalyst is precipitated, removed by filtration, the catalyst and distilled off excess monomer.
- the particularly low color number enables many fields of use of the oxetane group-containing (meth) acrylates according to the invention. Preferably, these can be used in dual-cure applications.
- the various reactive groups are suitable for curing formulations with different polymerization techniques, such as thermal and UV polymerization.
- the polymers are used in formulations as paints, adhesives, polyelectrolytes, dental cement and inkjets.
- the batch is dewatered, briefly cooled, and then the catalyst and the amount of methyl methacrylate corresponding to the distillate dewatering distillate are added and reheated to boiling.
- the methyl methacrylate / methanol azeotrope is separated and then the head temperature gradually increased to 100 0 C.
- the catalyst precipitated and cooled with stirring to room temperature. After filtration, the excess methyl methacrylate is distilled off on a rotary evaporator.
- the batch is dewatered, briefly cooled, and then the catalyst and the amount of methyl methacrylate corresponding to the distillate dewatering distillate are added and reheated to boiling.
- the methyl methacrylate / methanol azeotrope is separated and then the head temperature gradually increased to 100 0 C.
- the catalyst precipitated and cooled with stirring to room temperature. After filtration, the excess methyl methacrylate is distilled off on a rotary evaporator.
- the color number of the raw material was 49.
- Example 1 in contrast to the comparative example, shows a higher purity and a lower proportion of the low-boiling impurities, which in the comparative example are mainly due to the isopropyl methacrylate formed in the reaction.
- the high boiler impurities and the residual alcohol content show comparable values in both reactions.
