摘要
Abstract
Methyl glycolate is an important chemical raw material,so it is of great significance to study the synthesis process of methyl glycolate.The synthesis process of methyl glycolate was introduced,including chloroacetic acid hydrolysis method,methyl formate and formaldehyde coupling method,formaldehyde carbonylation esterification method,dimethyl oxalate hydrogenation reduction method,synthesis of ethylene glycol and methanol,biomass conversion method,methylal and formic acid free radical coupling method,formaldehyde and hydrocyanic acid addition method and one-step synthesis of glyoxal and methanol method.The advantages and disadvantages of each process were analyzed.The application of methyl glycolate in the fields of degradable plastic,food,medicine,pesticide and chemical industry was pointed out.The research progress of methyl glycolate production technology was analyzed.Finally,the synthesis process of methyl glycolate was summarized and prospected.There are many problems in the traditional production process of methyl glycolate,and it is difficult to produce on a large scale.The dimethyl oxalate hydrogenation reduction method to synthesize methyl glycolate and then to synthesize ethyl ester and polyglycolic acid has broad development prospects in China.After solving the problems existing in the whole process,large-scale industrial production will be realized.Biomass conversion process uses renewable cellulose and other resources as raw materials to produce methyl glycolate,which has the advantages of green and low-carbon,and helps to achieve Double Carbon goals.关键词
