摘　　要：以N,N′-双(2,2,6,6-四甲基-4-哌啶基)-N,N′-二醛基-1,6-己二胺、丙二酸二甲酯为原料,催化合成了N,N′-双(2,2,6,6-四甲基-4-哌啶基-1′-羟基-2′,2′-双甲酸甲酯基乙基)-1,6-己二胺。考察了反应时间、溶剂、催化剂、原料配比等对产品收率的影响。结果表明,优化工艺条件为:以对甲基苯磺酸为催化剂,甲苯为溶剂,n[N,N′-双(2,2,6,6-四甲基-4-哌啶基)-N,N′-二醛基-1,6-己二胺]∶n(丙二酸二甲酯)∶n(甲苯)∶n(对甲基苯磺酸)=1∶1.20∶1.00∶0.033,反应温度105~110℃,反应时间9 h,此条件下产品收率达94.74%。N,N′-bis(2,2,6,6-tetramethylpiperidin-4-yl-1′-oxhydryl-2′,2′-di-methyl formateyl-ethyl groupyl)hexane-1,6-diamine was synthesized from N,N′-bis(2,2,6,6-tetramethylpiperidin-4-yl)hexane-1,6-diamine and dimethyl malonate as catalyst.The effects of the reaction time,the solvent,the catalyst and the molar ratio of diketene to morpholine to benzene were studied.The results showed that under the optimized reaction conditions,4-toluenesulfonic acid acid was used as catalyst,methylbenzene was used as solvent,n(N,N′-bis(2,2,6,6-tetramethylpiperidin-4-yl)hexane-1,6-diamine)∶n(dimethyl malonate)∶n(methylbenzene)∶n(4-toluenesulfonic acid)=1∶1.20∶1.00∶0.033,reaction temperature was 105~110℃and reaction time was 9 h,the product yield rate reached 94.74%.
