ratio is important, only with the primary mercaptan. The trisulfide is the major product (75%) obtained from the stoichiometric charge of n-butyl mercaptan and sulfur ( 1 : l mole-atom ratio). If the n-butyl mercaptan :sulfur mole-atom ratio is 2, n-butyl disulfide is formed in 71% yield. Previous reports indicate that disulfides are formed in respectable yields from the base-catalyzed reaction of sulfur with primary mercaptan^.^^^ The results from variation in charge ratios are summarized in Table I.
