Abstract: Trimethyl borate is a kind of important boron compound and has widely applied in different 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.
