摘　　要：以苯烷基化制乙苯副产的高沸物为原料，用改性粘土做催化剂，使原料中的不饱和化合物和羰基化合物等反应生成大分子化合物，经蒸馏和精制后得到的电容器油，其物理、电气性能达到或超过了国外同类产品。研究了原料馏程、粘土用量和反应时间对产品溴值和收率的影响，得到的优化条件为：用２８０－３３０°Ｃ的馏份为原料，改性粘土用量为１０％，在１８０±５°Ｃ下反应２小时，产品溴值可降至４０以下，收率达７５％。扩大试验证明小试结果可靠，重复性好。An electric condenser oil was prepared from high boiling point fractions in ethylbenzene using modified clay as catalyst.Its electric characteristics are better than PXE、Theeffects of the b.p.range of fractions, the amounts of modified clay and the reaction timeon the yield and the bromine value were investigated, and the optimum reaction conditionswere found,The feedstock which was the fractions between 280-330℃ reacted for 2h inthe presence of 10%modified clay at 185±5℃,the yield of the oil being 75%and theIbromine value being lower than 40.The bench-scale research showed that the results werereliable.
