Bromine cyanide as titrimetric oxidant in non-aqueous media

Abstract

Bromine cyanide has been used for the potentiometric determination of sulphide, sulphite, thiocyanate, iodide, tin(II), arsenic(III),hydrazine hydrate, phenylhydrazine, 1,1-methylphenyldrazine and chloralhydrazine in glacial acetic acid and 1:1 acetic acid-acetic anhydride mixture, of thiourea, ethylthiourea, isopropylthiourea, benzylthiourea, α-phenylthiourea and o-tolythiourea in methanol, and of sodium methyl-, ethyl-,dimethyl-, diehtyl- and isopropyldithiocarbamates in ehtanol and acetonitrile media. The behaviour of bromine cyanide in these non-aqueous solvents has been compared with its behaviour in aqueous medium and with that of iodine cyanide in these non-aqueous solvents.
