| description | The invention discloses a method for preparing triphenylsilanol. The method comprises the following steps: firstly, generating a Grignard reagent from methyl tert-butyl ether (MTBE for short hereafter) and bromobenzene, and enabling the Grignard reagent to react with diphenyl dimethoxy silane to synthesize a reaction liquid with triphenyl dimethoxy silane; adding saturated alkane such as heptanes into the reaction liquid, further converting lower-layer magnesium salt into basic magnesium chloride, and leaving to stand to separate an organic phase above a water layer; performing high-temperature steam hydrolysis on the organic phase with an intermediate in weak acid water, directly collecting a white crude product of triphenylsilanol after solvents are carried out by steam, and further performing recrystallization, so as to obtain a finished product. All solvents are recycled and reused after being treated.
本发明是种制备三苯基硅醇的方法。它是首先利用甲基叔丁基醚（后文简称MTBE）和溴苯生成格氏试剂，再将此种格剂与二苯基二甲氧基硅烷反应合成含有三苯基甲氧基硅烷的反应液。往反应液中添加饱和烷烃如庚烷后再将下层镁盐 |
