摘要:酸三甲酯是众多含硼化合物中一种比较重要的有机酯,广泛用于各个行业,但是目前的生产エ艺在产率
及环境污染等方面存在較大河题。本文主要介绍了几种硼酸三甲酯合成エ艺,如直接合成、惟化合成、硼氧化物
作原料合成、明的卤化物为原料制取硼酸三甲醋等和一些其他合成エ艺方法。介绍了硼酸三甲酯的萃取精馏、恒
沸精馏和盐析的提纯分离方法,分析各种工艺优缺点。提出了今后研究硼酸三甲酯合成重点要放在直接合成和固
定床催化合成上,筛选出較好萃取剂和盐析剂,采用萃取精馏和盐析方法联合提纯分离

Abstract: Trimethyl borate is a kind of important boron compound and has widely applied in difterent
sectors. However, it is also associated with low yield and negative environment impact in conventional
process for producing trimethyl borate. This paper is aimed to introduce several methods for the
synthesis of trimethyl borate, such as direct synthesis, catalytic synthesis, and direct reaction with raw
materials of boron oxide. Trimethyl borate was prepared by direct reaction with raw materials of boron
halide and other methods of synthetic process. Several purification methods of trimethyl borate, such as
extractive distillation, azeotropic distillation and salting out, and their advantages and disadvantages
were discussed. The research should be more focused on direct synthesis, static catalytic bed, better
extraction agent, and salting-out agent. A multi-separation-method is proposed for the future separation
of trimethyl borate
Key words: trimethyl borate; synthesis; distillation; salting-out
