根据1,2-二苯乙烷产品的不同质量特点,对两种不同的提纯工艺进行比较,找出了两种处理方式对产品质量影响的差异。通过对两种不同提纯方法的比较并结合目前国内二苯乙烷的生产实际,提出了将两种处理方法进行优化合并的方案,对于国内二苯乙烷的工业化生产具有一定的指导和借鉴意义。 According to the different quality characteristics of 1,2-diphenylethane products, two different purification processes were compared to find out the difference between the two treatment methods on product quality. By comparing the two different purification methods and combining with the actual production of diphenyl ethane in China at present, a scheme of optimizing and combining the two processing methods is proposed, which has some guidance and reference significance for the industrialized production of diphenylethane in China .
