Treated with methanol,diethylmethoxyborane is synthesized via the new industrial synthesis process by necleophilic substitution reaction between trimethylborate and griganrd reagent which prepared by bromoethane and magnesium as raw materials. The effects of solvent,the ratio of raw materials,reaction time and temperature on the yield were investigated. The optimum process parameters were obtained based on several pilot plant experiments,the yield of product was 84 . 4% and the purity was 98 . 9%.
