Abstract
Bis (2 - 6 - dimethylmorpholinothiocarbonyl) monosulphide is prepared by reacting 2-6-dimethylmorpholine with carbon disulphide in an alkalene aqueous medium to produce a salt of 2-6-dimethyl-4-morpholinecarbodithioic acid, oxidising this to the corresponding thiuram disulphide with an oxidising agent such as potassium ferricyanide, chlorine, bromine, iodine or a peroxide, and converting the disulphide which precipitates to the monosulphide by treatment with sodium or potassium cyanide in an alcoholic medium. In an example 1 mole. of 2-6-dimethylmorpholine, 1 mol. of sodium hydroxide and 900 mol. water were mixed and carbon disulphide slowly dropped in. The clear yellow solution was treated dropwise with aqueous potassium ferricyanide and the dried precipitate was the disulphide. This was dissolved in 95% ethyl alcohol and refluxed with a solution of sodium cyanide in 50% ethyl alcohol and the bis(2-6-dimethylmorpholinothiocarbonyl) monosulphide precipitated by the addition of water. In a similar manner bis(morpholinothiocarbonyl) monosulphide, bis(2-5-dimethylmorpholinothiocarbonyl) monosulphide and bis(3-5-dimethylmorpholinothiocarbonyl) monosulphide are prepared from the appropriate morpholine starting compound.ALSO:A butadiene-styrene elastomeric copolymer is vulcanised with at least 0.4% of its weight of bis(2-6 - dimethylmorpholinothiocarbonyl) monosulphide. The composition may also contain 0.5 to 15% of sulphur, and the usual compounding ingredients.
