Mercurimetric determination of thiocyanates and isothiocyanates.


A method for the estimation of thiocyanates and isothiocyanates based on titration with o-hydroxymercuribenzoate (HMB) is described. The thioeyanates are determined as thiols either by direct titration with HMB in alkaline solution, or by back-titration of the unconsumed HMB. The isothiocyanates are converted by means of dimethylamine into the corresponding thioureas, and titrated with HMB in acid solution. Procedures for the selective determination of thioeyanates and isothiocyanates as well as for aliphatic and aromatic isothiocyanates in the presence of each other have been described.
