低黏度氢化蓖麻油聚氧乙烯(40)醚的合成

以氢化蓖麻油和环氧乙烷为原料,三氟化硼乙醚作催化剂,合成了氢化蓖麻油聚氧乙烯(40)醚。产物为极淡黄色,常温下为透明液体,羟值为70~80 mg KOH/g,皂化值为60~70 mg KOH/g,黏度为1 500~2 000 mPa.s。对影响目标产物黏度、色泽、外观、羟值和皂化值的主要因素进行了优化,得到了适宜的反应条件:w(三氟化硼)=0.8%~1.3%,反应温度100~120℃。用500 L反应釜进行扩试生产,得到的产品色泽为极淡黄色,常温下为透明液体,羟值为70.3 mg KOH/g,皂化值为63.2 mg KOH/g,黏度为1 620 mPa.s。

Synthesis of Low Viscosity POE(40) Hydrogenated Castor Oil Ether

POE(40) hydrogenated castor oil ether was synthesized from hydrogenated castor oil and ethylene oxide,with boron trifluoride ether complex as catalyst.The product obtained by this method was a very light yellow,transparent liquid in room temperature.Hydroxyl value of products range from 70 to 80 mg KOH/g,saponification value range from 60 to 70 mg KOH/g,and viscosity range from 1 500 to 2 000 mPa·s.The main influencing factors on viscosity,color,appearance,hydroxyl value,and saponification value of the products were optimized.The suitable reaction conditions were obtained,w(boron trifluoride)=0.8%～1.3%,reaction temperature 100～120 ℃.With the 500 L reactor to scale-up trial production,the product was a very light yellow,transparent liquid in room temperature.Hydroxyl value is 70.3 mg KOH/g,saponification value is 63.2 mg KOH/g,and viscosity is 1 620 mPa·s.
