摘　　要：以促进剂M和叔丁胺为原料、氧气为氧化剂合成了促进剂N-叔丁基-2-苯并噻唑次磺酰胺(TBBS),考察了叔丁胺与促进剂M配比、反应温度、反应压力及搅拌转速对TBBS收率和熔点的影响。结果表明,当n(叔丁胺)/n(促进剂M)为14/1、反应温度为50℃、反应压力为0.7 MPa且搅拌转速为130 r/min时,TBBS的收率达95.4%,熔点达107.2℃。通过对氧气氧化法和次氯酸钠氧化法合成的TBBS的熔点、游离胺、甲醇不溶物、硫含量和纯度分别进行检测,发现由氧气氧化法合成的TBBS的各项指标均稍优于次氯酸钠氧化法。The accelerator N-tert-butyl-2-benzothiazole sulfonamide(TBBS)was synthesized by using accelerator M and tert-butylamine as raw materials and oxygen as oxidant.The effects of the ratio of tert-butylamine and accelerator M,reaction temperature,reaction pressure and stirring speed on the yield and melting point of TBBS were investigated.The results showed that when n(tert-butylamine)/n(accelerator M)was 14/1,reaction temperature was 50℃,reaction pressure was 0.7 MPa and stirring speed was 130 r/min,the yield of TBBS reached 95.4%,the melting point reached 107.2℃.Through the detection of melting point,free amine,methanol insoluble,sulfur content and purity of oxygen oxidation products and sodium hypochlorite oxidation products,it was found that the indexes of oxygen oxidation products were slightly better than those of sodium hypochlorite oxidation products.
