ABSTRACT:
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.sup.1 and R and R.sup.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.
