This paper reviews some chemical and physical characteristics of methanesulfonic acid and the short-chain alkanesulfonic acids in general. The aqueous solubility of metal methanesulfonates, the conductivity of aqueous methanesulfonic acid (MSA) solutions and the low toxicity of MSA all make MSA(aq) an ideal electrolyte for many electrochemical processes, especially those involving tin and lead. Aspects of aqueous process effluent treatment, acid recovery and metal alkanesulfonate salt preparation are also environmentally favorable. Emphasis in this paper is given to rationalizing the rapidly growing commercial preference for MSA(aq) as an electrochemical electrolyte, especially with respect to the substitution of MSA for HBF₄ in the electroplating of Sn/Pb solder. Economic aspects of MSA are also considered.

甲磺酸的环境效益。比较特性和优​​势

本文概述了甲磺酸和短链烷磺酸的一些化学和物理特性。金属甲磺酸盐的水溶性，甲磺酸水溶液（MSA）的电导率以及MSA的低毒性都使MSA（aq）成为许多电化学过程（尤其是涉及锡和铅的电化学过程）的理想电解质。含水过程废水处理，酸回收和金属链烷磺酸盐盐制备的方面在环境上也是有利的。本文的重点在于合理化快速增长的商业上偏爱将MSA（aq）用作电化学电解质，尤其是在电镀Sn / Pb焊料中用MSA代替HBF ₄时。还考虑了MSA的经济方面。
