Abstract

IN A PROCESS FOR ESTERIFYING (METH)ACRYLIC ACID WITH AN ALKANOL IN THE PRESENCE OF AN ESTERIFICATION CATALYST IN WHICH UNREACTED STARTING COMPOUNDS AND THE (METH)ACRYLIC ESTER FORMED ARE SEPARATED OFF BY DISTILLATION AND A BOTTOM PRODUCT CONTAINING OXY ESTERS IS OBTAINED, THE BOTTOM PRODUCT IS SEPARATED OFF AND EITHER THE BOTTOM PRODUCT IS DIRECTLY ADMIXED WITH OLIGOMERIC (METH)ACRYLIC ACID AND THE OXY ESTERS PRESENT IN THE BOTTOM PRODUCT ARE DISSOCIATED AT AN ELEVATED TEMPERATURE IN THE PRESENCE OF ACID CATALYSTS DIFFERENT FROM OLIGOMERIC (METH)ACRYLIC ACID, OR THE OXY ESTERS ARE FIRST SEPARATED BY DISTILLATION FROM THE BOTTOM PRODUCT, THE DISTILLATE IS ADMIXED WITH OLIGOMERIC (METH)ACRYLIC ACID AND IS DISSOCIATED AT AN ELEVATED TEMPERATURE IN THE PRESENCE OF ACID CATALYSTS DIFFERENT FROM OLIGOMERIC (METH)ACRYLIC ACID.
