| titleOfInvention | The synthetic method of rubber accelerator tetrabenzylthiuram disulfide |
| abstract | The invention discloses a kind of synthetic method of rubber accelerator tetrabenzylthiuram disulfide, the method is by after solvent and dibenzylamine mixing, dithiocarbonic anhydride is dripped under the condition of temperature 0 ~ 20 DEG C, time for adding is 1.5 ~ 2 hours, stirring reaction 1 ~ 3 hour, be warming up to 40 ~ 70 DEG C again, below the liquid level of reactant, slowly pass into pressurized air carry out oxidizing reaction, reaction times is 4 ~ 8 hours, after reaction, press filtration is carried out to product, solvent recovery cycle in filtrate is used, filter cake vacuum-drying is obtained tetra-benzyl thiram disulfide; Wherein, described solvent is the mixture of mol ratio 1:8:1 of methyl alcohol, ethanol, toluene.Method of the present invention, simple process, material cost is low, produces without waste water, and the recyclable Posterior circle of solvent uses, and the yield of product is high, and purity is high. |
