Process for synthesizing an ammonia complex of zinc bisdithiocarbamate
(57) Abstract

A process for synthesizing ammonia complexes of zinc bisdithiocarbamates, starting from carbon disulfide, ammonia, an alkylenediamine and zinc oxide, in which an aqueous mixture of alkylenediamine, carbon disulfide and ammonia in the molar ratio of 1:2:<2, i.e., not 1:2:2, as would be necessary for synthesis of the ammonium alkylene bisdithiocarbamate intermediate product, is reacted with zinc oxide.

Claims (4)

  1. A process for synthesizing ammonia complexes of zinc bisdithiocarbamates, comprising reacting an aqueous mixture of alkylenediamine, carbon disulfide and ammonia in a molar ratio of approximately 1:2:0.6-1.5, respectively, with zinc oxide.
  2. The process according to claim 1, wherein the alkylenediamine is an aliphatic 1,2-diamine with 2 to 6 carbon atoms and primary amino groups.
  3. The process according to claim 1, wherein the alkylenediamine is ethylenediamine.
  4. The process according to claim 1, wherein the alkylenediamine is propylenediamine.
