均二苯乙烯双三嗪类荧光增白剂的晶型转变

The Crystalline Form Transition of Bis (triazinyl)aminostilbene Derivative Fluorescent Brightener

均二苯乙烯双三嗪类荧光增白剂是目前世界上商品化最多的一类荧光增白剂。经Ｘ－射线衍射法分析发现，该类化合物存在两种或三种晶型，并且性能不同，本文简要介绍了几种不同介质下的晶型转变方法。

Abstract Bis(triazinyl)aminostilbene derivative fluorescent bringhtener has been found in two or three kinds of crystalline forms with different properties.In this artical several methods for crystalline form trnsition were briefly introduced.
