Abstract
The invention relates to a process for synthesizing alkylene bisdithiocarbamates or the ammonia adducts thereof as well as mixtures that can be synthesized thereby. The starting materials are carbon disulfide, ammonia, a diamine and a metal oxide, which may be manganese(II) oxide, or the hydrate or hydroxide thereof. The metal oxide, its hydrate or hydroxide thereof is allowed to react either with a mixture syntheiszed from an alkylenediamine, carbon disulfide and ammonia in water, or with an aqueous solution of the ammonium alkylene bisdithiocarbamate. The concentration of the individual starting materials both relative to each other and to water is of prime importances as to which compounds in particular are ultimately obtained.
