摘 要: | 用苯溶解邻氰基氯苄,再与亚磷酸三乙酯进行酯化反应,合成荧光增白剂ER。改进方法与原方法相比,不仅节省了反应时间,而且酯化反应产率提高了18-23%。用合成的荧光增白剂ER制备了其水分散液。

Improved synthetic method for fluorescent whitening ERand preparation of its dispersion |
| |
Abstract: | Fluorescent whitening agent ER was synthesized by the esterification reaction of phosphorous ether with o cyanobenzyl chloride dissolved in benzene. This process not only saved reaction time, but also increased the yield for 18%~23%. The dispersion of fluorescent whitening agent ER was prepared. |
