PRODUCTION OF METHACRYLIC ACID ALKYL ESTER

摘要

PROBLEM TO BE SOLVED: To efficiently obtain the subject compound at a high reaction rate by carrying out a transesterification reaction while distilling a by-product alcohol. SOLUTION: In this method for producing the objective compound by performing the transesterification reaction of a methacrylic acid ester with an alkyl alcohol by a batch operation, a vapor rate of by-product alcohol defined by the equation [L/h.nol]=(D+Q)/MROH×R×T/(P×F) D is mass [g/h] of the by-product alcohol in a distillate per unit; Q is mass [g/h] of the by- product in a reflux per unit; MROH is molecular weight [g/mol] of by-product alcohol; R is a gas constant (8.31) [J/mol.K]; T is a temperature [K] of the top of the column; P is pressure [kPa] at the top of the column; F is a fed mol amount [mol] of the raw material alcohol) is 25-200 L/h.mol is 25-200 L/h.mol to perform the reaction.
