Vulcanization Characteristics of N,N'-Dithioamines in Furnace Black Stocks

Reactions of Phthalimide and Potassium Phthalimide With Sulfur Monochloride

“…The reaction of ainines and amides with sulfur monochloride (S2CI2) in a variety of nonpolar solvents and in absolute ethanol has been reported to j~ield mixtures of N,N'-dithio and N,N'-polythio compounds (1)(2)(3)(4)(5)(6)(7)(8)(9)(10)(11). In a few instances, substances identified as N,N'-monothio derivatives of anlines and amides have been isolated (2,3,12,13).…”

Elastomers

“…AtyV'-Dithioamines offer a means of replacing sulfur as the curative agent in rubber mixtures-e.g., those containing certain types of furnace carbon blacks which tend to scorch during mixing or processing (144)• Morpholine sulfide vulcanizes natural rubber, GR-S, and Hycar-OR, and gives slow cures with GR-I (Butyl rubber), without the addition of elemental sulfur (131). 4,5-Dimethyl-2-mercaptothiazole-an aliphatic relative of the famous mercaptobenzothiazole-is of potential importance as an accelerator since it can be prepared economically from raw materials of a nonaromatic source (101).…”

Methods of Dithiodimorpholine Production

“…The process main studies were: synthesis, expendable washing of suspension, filtration, granulation, drying and packing ( Fig. 1) [1].…”
