STUDY ON THE SYNTHESIS OF CARDANOL GLYCIDYL ETHER

以腰果酚和环氧氯丙烷为原料,在苄基三乙基氯化铵的催化作用下合成了腰果酚缩水甘油醚。考察了反应条件对产物收率的影响,腰果酚缩水甘油醚的适宜合成工艺条件为:n(腰果酚)∶n(环氧氯丙烷)∶n(氢氧化钠)=1∶6∶3,催化剂用量为2%,反应温度70℃,反应时间10h,腰果酚缩水甘油醚的产率达到89.1%。利用红外光谱对腰果酚缩水甘油醚进行结构表征。常压下采用比重瓶法和乌氏黏度计法对腰果酚缩水甘油醚的密度和黏度进行测定,结果表明:腰果酚缩水甘油醚的密度在给定温度范围内随着温度的升高呈直线下降,黏度呈对数关系下降。

Cardanol glycidyl ether （CGE） was synthesized by using cardanol and epoxy chloropropane as raw materials and Benzyl triethyl ammonium chloride （TEBA） as the catalyst. The process condi- tions were optimized： n（cardanol） ： n（epoxychloropropane） ： n（sodium hydroxide） =1 ： 6 ： 3, cata- lyst amounts was 2%, reaction temperature was 70 ℃, reaction time was 10 h and the yield of CGE could be up to 89. 1%. The products structures were characterized by FT-IR. Under atmospheric pressure, the density and viscosity of CGE were measured by using the Ostwald Sprengel-type pyc- nometer and the Ubbelohde capillary viscometer. The results showed that within the given tempera ture range, both the densities and viscosities would decrease with temperature increasing, and the densities decreased linearly while the viscosities decreased logarithmically.
