Abstract At temperatures in the region of 140°, organic polysulfides undergo disproportionation resulting from thermal fission of S—S bonds and recombination of the fission products. In the presence of olefins a considerable proportion of the fission products become attached to ethylenic centers of the olefin, forming mixed mono- and polysulfides. The major part of the monosulfide product is fully saturated, hydrogen capture occurring during, or subsequent to the formation of adducts from the olefin and sulfurated fragments; unsaturation, however, appears in the polysulfide portion. The polysulfides are capable of producing monothio cross-links between the original olefinic molecules only in so far as they are able to yield up elementary sulfur to the olefin, and when the original olefin is a polyisoprene, the tendency towards the formation of a high proportion of intramolecular cyclic sulfide still further reduces the opportunity for formation of intermolecular sulfur-cross-linked products.

Abstract 1. Mono-, di-, and trimethylamine when treated with benzyl and tolyl mercaptan give disufides ; on the other hand, thioglycolic acid gives the monosulfide. 2. Aniline and diphenylamine do not react with mercaptans or organic sulfides. 3. Mono-, di- and trimethylamine react with organic polysulfides. The tri- and tetrasulfides of the tolyl and benzyl series give disulfides by desulfurization. The glycolic acud sulfides are desulfurized to monosulfide. 4. The relative desulfurization activities of mono-, di- and trimethylamine are (CH3)3N < CH3NH2 < (CH3)2NH. This order is the same as for the basicity of these amines. Aromatic amines, because of their weak basicity, do not react with organic polysulfides. 5. The relative ease of desulfurization is in the order glycolic acid > benzyl > tolyl. The more sulfur a polysulfide contains, the more readily it desulfurizes. The mercaptan to disulfide reaction rate is faster than desulfurization of polysulfides.
