THE DETERMINATION OF ORGANIC MERCAPTAN AND DISULFIDE GROUPS

Abstract

Identifi rs: Mercaptan.A polarographic method was developed for the determination of mercaptans in the presence of disulfides and vice versa. This method does ot istinguish between separate mercaptans but yields only the total mercaptan and disulfide concentration in solution. The kinetics of the N-S acyl shift was studied for N-acetyl and S-acetyl-2-mercaptoethylamine and found to be incapable of polarographic investigation. The residual current in orthophosphate medium was determined to arise from the formation, in acid medium, of monobasic mercurous phosphate. A odic polarographic data for 15 amine mercaptans are reported and certain general conclusions about their behavior are drawn. The complexing ability of 5 of these amine mercaptans was studied with Cu and Zn ions. (Author)
