Abstract
Official abstract text for this publication.
A process for preparing an ester of (meth)acrylic acid or a derivative thereof comprises reacting (meth)acrylic acid or a derivative thereof with glycerol carbonate at a reaction temperature of 10 to 150° C. without a solvent in the presence of at least one enzyme catalyzing the esterification reaction.
First claim
Opening claim text (preview).
We claim: 1. The process for preparing an ester of (meth)acrylic acid or a derivative thereof by reaction of (meth)acrylic acid or an ester thereof with glycerol carbonate at a reaction temperature of 10 to 150° C. without a solvent in the presence of at least one enzyme catalyzing the esterification reaction. 2. The process according to claim 1 wherein the reaction temperature is in the range from 10 to 100° C. 3. The process according to claim 1 , wherein the enzyme used is a lipase from Candida antarctica. 4. The process according to claim 1 , wherein the at least one enzyme is present on a carrier material. 5. The process according to claim 1 , wherein the (meth)acrylic acid ester used is a C 1-12 -alkylester. 6. The process according to claim 1 , in the presence of a drier. 7. The process according to claim 1 , in the presence of at least one stabilizer. 8. The process according to claim 1 , wherein water, alcohols or mixtures thereof are removed during the reaction by distillation. 9. The process according to claim 1 , wherein the molar ratio of (meth)acrylic acid or an ester thereof to glycerol carbonate is in the range from 2:1 to 30:1. 10. The process according to claim 1 , wherein the resulting glycerol carbonate (meth)acrylate is converted into glycerol mono(meth)acrylate after the reaction. 11. The process according to claim 1 , wherein the reaction temperature is in the range from 20 to 90° C. 12. The process according to claim 1 , wherein the reaction temperature is in the range from 40 to 60° C. 13. The process according to claim 1 , wherein the (meth)acrylic acid ester used is a methyl, ethyl or propyl ester.
