摘要：

A method for determining small amounts of formic acid in mixtures from the synthesis of phenol from cumene, in particular those obtained after the decomposition of cumene hydroperoxide, is described. The determination consists in extraction of fromic acid as the sodium salt, acidification and esterificaiton to methyl formate followed by gas-liquid chromatography with an internal standard. © 1978.
