摘要：

A method has been developed for the identification of mercaptans in petroleum fractions by reaction with trialkyltin reagents. The derivatives formed have been characterized and quantified by Sn-119 n.m.r. spectrometry. Sulphides in petroleum fractions were first reduced to thiols by calcium in liquid ammonia. The thiols were then derivatized with bis(tri-n-butyltin) oxide (TBTO) and characterized in situ by Sn-119 n.m.r. spectroscopy. This study also shows that a unique chemical shift may be attributed to each class of sulphydryl-containing compound.
