摘要:以吗啉和乙酸为原料合成N-乙酰吗啉,考察了原料配比、反应温度和带水剂对反应的影响。试验结果表明,采用带水剂可使N-乙酰吗啉的收率明显提高,在加入10%带水剂、反应温度为40-145°C和原料配比n(乙酸)∶n(吗啉)/摩尔比为0.95下,N-乙酰吗啉的收率91.5%。反应产物经减压蒸馏后可得到大于98.5%的高纯度N-乙酰吗啉。
N-Acetyl morpholine was synthesized using acetic acid and morpholine as raw materials. The influencing factors including the mole ratio of acetic acid to morpholine, reaction temperature and dehydraing agent were investigated. The yield of N-acetyl morpholine reachs 91.5 % in the existence of dehydrating agent, at temperature of 40 - 145℃, and with molar ratio of acetic acid: morpholine = 0.95:1. The purity of N-acetyl morpholine distillated is 98.5 %.
