A process for the preparation of alkane sulfonic acid and alkane sulfonyl chloride.

摘要

A process is disclosed for the efficient production of high purity alkane sulfonic acid and/or alkane sulfonyl chloride product wherein a compound of the formula RSX, where X is hydrogen or -SR<1> and R and R<1> are alkyl radicals is continuously reacted with chlorine in aqueous hydrochloric acid to produce a turbulent evolution of hydrochloride gas, passing the reactants through stationary mixing elements to promote plug-flow, and separately withdrawing a product. Apparatus for this process is also disclosed.
