摘　　要：本文在实验过程中通过对酮胺比、反应时间、反应温度、酸胺比四个影响因素的研究实验来分析对产品质量的影响,最后用正交试验的方法来研究分析四个影响因素。结果表明,酮胺的最佳比例是2:1(比例为摩尔比),反应时间是7.5h,反应温度120~125℃,酸胺的最佳比例为0.2:1(比例为摩尔比)。通过正交试验可以得出酮胺比的变化对产品质量的影响最大,其次就是酸胺比、反应时间、反应温度。且在成盐反应时,需将体系的水除去,并在缩合时,滴加丙酮时的速度应控制,使丙酮可以完全的反应,在减压蒸馏时,大约每30min提高约30℃。In this paper,the effects of four factors on the quality of the product were analyzed through four factors:ketone amine ratio,reaction time,reaction temperature and acid amine ratio.The results show that the optimum ratio of ketone amine is 2:1(mole ratio,reaction time is 7.5 h,reaction temperature is 120~125℃).The optimum ratio of acid amine is 0.2:1(mole ratio).By orthogonal test,it can be concluded that the change of ketone amine ratio has the greatest influence on product quality,followed by acid amine ratio,reaction time,reaction temperature.During condensation,the rate of acetone drop should be controlled so that acetone can react completely and increase by about 30℃every 30 min during vacuum distillation.
