Embodiment Construction

[0027] This example uses methyl methacrylate and dimethylaminoethanol as raw materials, calcium metal as a catalyst, and phenothiazine as a polymerization inhibitor to prepare the target product of dimethylaminoethanol methacrylate through transesterification. The raw materials used are methyl methacrylate, A.R. grade, produced by Tianjin Chemical Reagent Factory; dimethylaminoethanol and metal calcium are both A.R. grade, produced by Shanghai Reagent No. 1 Factory; phenothiazine, chemically pure, China Pharmaceutical Group Shanghai Chemical Reagent Company production. Infrared detection The detection spectrum was carried out by Ncolet FT-Jh 170SX infrared spectrometer.

[0028] In a 250 three-necked flask with a thermometer, a condenser, and a split column, add methyl dimethacrylate and methylaminoethanol in a molar ratio of 2:1, and a resistance that is 0.0075 times the mole of dimethylaminoethanol, respectively. Polymer phenothiazine and 0.075 times the catalyst metal calc...

Abstract

A process for preparing substituted or non-substituted aminoalkyl acrylate is characterized by that in the presence of catalyst (alkali-earth metal) the acrylate or substituted acrylate and alkylamino alcohol are subjected to ester exchange reaction to obtain said product.

Description

technical field [0001] The invention relates to a method for preparing substituted or unsubstituted aminoalkyl acrylate through transesterification in the presence of a catalyst. Background technique [0002] Substituted or unsubstituted aminoalkyl acrylates are a class of monomeric compounds with multifunctional activity. Because of the functional groups of olefins, amines and esters in the structure, under certain conditions, they can be further synthesized by addition, polymerization, hydrolysis, etc. And quaternization and other chemical reactions, to obtain different types of compounds and are widely used in many fields such as light industry, textile, chemical industry, medicine and environmental protection. [0003] The synthesis of substituted or unsubstituted aminoalkyl acrylates can be accomplished through transesterification of acrylates or substituted acrylates with alkylamino alcohols. Its reaction process is: [0004] <chemistry num="001"> <chem fi...
