摘要
(CN108147985) The invention relates to the field of rubber vulcanizing promoter and particularly relates to a preparation method of zinc dibutyldithiocarbamate. The preparation method comprises the following stepsof: dropping carbon disulfide into reaction solution containing zinc oxide, dibutylamine, a dispersing agent and a first organic solvent to carry out reaction, and after reaction is ended, obtaining the zinc dibutyldithiocarbamate, wherein the first organic solvent is insoluble in water and the obtained zinc dibutyldithiocarbamate is insoluble or slightly soluble in the first organic solvent. Thepreparation method of the zinc dibutyldithiocarbamate has the beneficial effects that an anhydrous solvent method is adopted to prepare the zinc dibutyldithiocarbamate, so that the generation of salt-containing waste water is avoided; since the first organic solvent is insoluble in water, the first organic solvent and the water can be separated by liquid-separating operation; the first organic solvent after water removal can be repeatedly utilized, so that the solvent cost is reduced and simultaneously the yield of a product is increased; the operation is simple and convenient, the generationof the salt-containing waste water is avoided, and the method is a cleaning environment-friendly new method, and is easily applied in large-scale production practice.
