Abstract

Before formic acid is selectively and catalytically decomposed e.g. as in Specification 901,141, in a mixture which contains C2-8 aliphatic carboxylic acids e.g. acetic acid and other organic contaminants, the mixture is passed in the vapour phase over an absorbing solid having a specific surface area of 100 sq.m./gm. Solids specified are alumina, silica, a mixture of alumina and silica, and active carbon, and they preferably have an acidic surface. The absorption temperature is between 80 DEG and 220 DEG C. Specifications 737,439, 820,693 and 844,598 also are referred to.
