摘　　要：N-十二烷基吗啉是一种应用广泛的精细化工产品,其在矿物浮选方面的使用尤为重要,在氯化钾装置采用的最先进的反浮选-冷结晶法浮选工艺中,均以N-十二烷基吗啉为主的复合浮选剂,这种工艺得到的氯化钾产品质量可以达到国际先进水平。本工艺以十二醇和吗啉为原料,在Ni-Cu负载型催化剂的作用下,临氢连续低压合成N-十二烷基吗啉,十二醇的单程转化率为98.41%,产品收率达到95.35%,产品纯度为97%。N-dodecyl morpholine is one of the widely used fine chemical products , especially important for its use in mineral flotation.Among the potassium chloride （ KCl ） plant which adopts the most advanced reverse flotation -cold crystallization method in flotation process , N-dodecyl morpholine is mainly used for composite flotation agent.The quality of potassium chloride can reach the international level with this process.The process was studied , which N-dodecyl morpholine was synthesized under hydrogen and continuous law pressure conditions with the dodecyl alcohol and morpholine as raw material and the function of Ni-Cu supported-type catalyst, the per pass conversion of dodecyl alcohol was 98.41%, the yield of the product reaches 95.35%, the purity of the product was 97%.
