| 摘 要： | 采用同时滴加NaCl、促进剂M的钠盐和硫酸溶液的方法合成了橡胶硫化促进剂DZ(N,N-二环己基-2-苯并噻唑次磺酰胺)。较佳合成条件为:n(促进剂M):n(二环己胺):n(NaClO)=1:(0．9～0．95): (1．35～1．40),反应温度36～46℃,反应时间3 h,pH值9．8～10．2。中型试验结果表明:DZ收率大于初熔点大于95℃、熔程0．5～1．0℃、游离2,2′-二硫代苯并噻唑质量分数小于0．5%。

| Abstract: | A new process for the synthesis of rubber sulfidation accelerant DZ(N,N′-diecyl-2-benzothi- cazole) by simultaneous addition of three reactants was studied.The influences of n (M):n (C_(12)H_(23)N):n (NaClO),pH value,temperature and reaction time on the yield and the quality of DZ were investigated.The optimal conditions were found as follows,n(M):n(C_(12)H_(23)N):n(NaClO)= 1:(0.9-1.95):(1.35-1.40),pH=9.8-10.2,temperature 3-46℃,reaction time 3 h.With melting points,yield and DM content being adopted as the main criterions,a high quality product, which has an initial melting point of 95℃,melting range 0.5-1℃and free DM content below 0.5%,was obtained with the yield above 80%. |
