Title:
PRODUCTION OF 2-AMINOETHYLESTER OF METHACRYLIC ACID
Document Type and Number:
Japanese Patent JPH04356448
Kind Code:
A
Abstract:

PURPOSE: To obtain a 2-aminoethylester of methacrylic acid useful as modifier, processing agent, etc., for fiber, etc., in high selectivity, high yield and high purity from a reaction solvent by a ready operation even when an inexpensive reaction solvent is used.

CONSTITUTION: When methacrylic acid(MA) is reacted with an aziridine(Az), preferably ethyleneimine, propyleneimine, hydroxyethylethyleneimine, cyanoethylethyleneimine and/or aminoethylethyleneimine to produce 2- aminoethylester compounds of methacrylic acid, the reaction is carried out while keeping ratio of water in a reactional system of water or an aqueous solvent to 5-90wt.% keeping ratio of total charge molar amounts of MA/Az to 1/2 to 20/1 and keeping ratio of molar concentration of MA/Az in the reactional system to ≥1.5, and simultaneously, keeping ratio of free MA equivalent weight in the reactional system / equivalent weight as a base of Az used for reaction to ≥1.5 by adding an inorganic acid during reaction to provide the objective compound in high purity and in high yield at a low cost.
