Verfahren zur Herstellung von Hydroxyalkyl (Meth)acrylaten

摘要

In a process for producing hydroxyalkyl (meth)acrylates by the reaction of (meth)acrylic acid with an alkylene oxide, a thermally and chemically stable anion exchange resin is used as a catalyst, which resin contains a repeating unit represented by the following formula (1) as a component: wherein A is a straight chain alkylene group having 3 to 8 carbon atoms, each of R<1>, R<2>, and R<3> is a hydrocarbon group or an alkanol group having 1 to 4 carbon atoms, which may be substituted with a hydroxyl group, X<-> is a counter ion coordinated with an ammonium group, where the substituent A with the ammonium group may be substituted at any position of a benzene ring, and the benzene ring may be substituted with an alkyl group or a halogen atom. The process can economically efficiently produce hydroxyalkyl (meth)acrylates without disadvantages such as deterioration in properties of a distillation residue.
