芳烃石油树脂生产工艺探索

Manufacture of Aliphatic Petroleum Resin

石脑油裂解制乙烯副产的碳九重芳烃，在ＢＦ３气体催化下，采用低温聚合工艺生产的石油树脂色泽浅、成本低，操作简单易行。

Aliphatic petroleum resin (Saftering point ≥100℃, and good color) can be oblained by cation polymerizing from by-product C 5-fraction in ethylene plant. It may be prepared by presenting Comprised AlCl 3 in benzene medium Thuo benzene 100 and AlCl 3 2 5 parts are well mixed, to give a homogeneous catalysts comple. Then 100 parts C 5-fraction should be added dropwisely (added time was 40min), stirring at refluxing-temp for 80min and firally about 55-60%, yiold of resin, wich saftening temp, 80-105℃ and Gardner color 6-8 could be reaehed.
