    • The present invention relates to a process for producing nylon-6,6 by a) providing a muconic acid starting material selected from muconic acid, esters of muconic acid, lactones of muconic acid and mixtures thereof, b) subjecting the muconic acid starting material provided in step a) at least to some extent to a reaction with hydrogen in the presence of at least one hydrogenation catalyst Hb) to give adipic acid, c1) subjecting the muconic acid starting material provided in step a) to some extent to a reaction with hydrogen in the presence of at least one hydrogenation catalyst Hc1) to give 1,6-hexanediol, or c2) subjecting the adipic acid obtained in step b) to some extent to a reaction with hydrogen in the presence of at least one hydrogenation catalyst Hc2) to give 1,6-hexanediol, d) subjecting the 1,6-hexanediol obtained in step c1) or c2) to amination in the presence of an amination catalyst to obtain hexamethylenediamine, e) subjecting the hexamethylenediamine obtained in step d) and at least a portion of the adipic acid obtained in step b) to polycondensation to obtain nylon-6,6.
    • 本发明涉及一种通过以下方法生产尼龙-6,6的方法:a)提供选自粘康酸,粘康酸的粘蛋白的酸,粘康酸的内酯及其混合物的粘康酸起始材料,b)使提供的粘康酸起始物料 在步骤a)至少在一定程度上与至少一种氢化催化剂Hb)存在下的氢反应得到己二酸,c1)使步骤a)中提供的粘酸原料在一定程度上与 在至少一种氢化催化剂Hc1存在下进行氢化)得到1,6-己二醇,或c2)在步骤b)中获得的己二酸在一定程度上与至少一种氢化催化剂Hc2存在下的氢反应 ),得到1,6-己二醇,d)在胺化催化剂存在下使步骤c1)或c2)中得到的1,6-己二醇进行胺化得到六亚甲基二胺,e)使步骤d)中得到的六亚甲基二胺 和步骤b)中获得的至少一部分己二酸进行缩聚以获得尼龙-6,6。
