The invention comprises salts of di-(b -phenethyl)-dithiocarbamic acid with amines (e.g. primary, secondary and tertiary aliphatic, cycloaliphatic, araliphatic and aromatic amines) or with heavy metals (e.g. calcium, magnesium, iron, zinc, copper and mercury). In examples of the preparation of these compounds: (1) di-(b -phenethyl)-amine is stirred with carbon disulphide in an aliphatic hydrocarbon solvent to produce the di-(b -phenethyl)-amine salt of di-(b -phenethyl)-dithiocarbamic acid; (2) the reaction of (1) is effected in aqueous caustic soda and the resulting aqueous solution of the sodium salt of di-(b -phenethyl)-dithiocarbamic acid is reacted with an aqueous solution of zinc sulphate to precipitate the zinc salt; the zinc sulphate may be replaced by a water-soluble salt of another heavy metal (e.g. iron or mercury) or by an amine (e.g. mono-, di- or tri-methylamine, mono- or di-ethylamine, di-cyclohexylamine, N-methylcyclohexylamine, di-phenylamine or piperidine). The products are useful as rubber vulcanization accelerators.
