苯甲酰甲酸合成的研究

STUDY ON THE SYNTHESIS OF BENZOYLFORMIC ACID

水做介质，季铵盐做相转移催化剂，在温度５０～６０ ℃，碱性条件下高锰酸钾氧化苯乙烯制取苯甲酰甲酸，产率６５％～７２．４％。

In alkaline aqueous solution using quaternary ammonium salts as the phase transfer catalyst at 50 -60 C styrene was oxidated to benzoylformic acid by potassium permanganate. The yields were 65 % -72. 4 %.
