钻井液用乙基糖苷合成中产品颜色的研究

Study on colour in ethyl glucoside synthesis for drilling fluid

为了得到性能好的乙基糖苷,需要在产品制成过程中控制产品的颜色,而产品的合成、脱醇和漂白工艺都会影响产品的颜色。通过对影响合成的工艺因素逐一研究发现,通过控制加料方式、搅拌速度、醇糖比、剂糖比和反应温度,可以减少葡萄糖副反应的发生,合成出浅色乙基糖苷粗产品。

In order to get the good performance of the ethyl glucoside,we need to control the product color,and synthesis,dealcoholization and bleaching process will all affect the product＇s color.In this paper,by studing the influence factors on synthesis process one by one,it was found：using appropriate way of feeding,controlling stirring speed,sugar and alcohol ratio,catalyzer and sugar ratio,reaction temperature,reducing the occurrence of side reaction of glucose is key to synthesise light crude products of ethyl glycoside.
