Corrosivity of steel and other metals in chlorosulphonic acid

Abstract

Steel, stainless steel, clad steel, and aluminium are used in the transport and handling of chlorosulphonic acid, which is used as a sulphonating agent in the manufacture of synthetic drugs and as a warfare chemical. The choice of the appropriate material of construction for tank wagons and handling equipment depends upon the rate of corrosion of these materials in chlorosulphonic acid. Experiments show that corrosion can vary widely depending upon the percentage of chlorosulphonic acid present.
