Process for the preparation of bistriphenylsilyl chromate

摘要

Disclosed is a process for the preparation of bistriphenylsilyl chromate, wherein triphenylchlorosilane, potassium dichromate and any one selected from alkali metal oxides, alkali hydroxides and alkali metal carbonates are reacted in, as solvent, a mixture of glacial acetic acid and a hydrocarbon solvent at a certain temperature, whereby bistriphenylsilyl chromate having high purity can be obtained with high yield.
