摘要:
通过工业新工艺合成,以溴乙烷和镁粉为原料制备格氏试剂,与硼酸三甲酯发生亲核取代反应,经甲醇后处理得到二乙基甲氧基硼烷.考察了溶剂、原料配比、反应时间及温度等因素对二乙基甲氧基硼烷收率的影响,通过多次中试实验,获得了各步反应的最佳工艺参数,产品收率为84.4;,产物GC纯度为98.9;.
Abstract:
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;.
