Abstract: Aromatic solvent naphtha was obtained by two-stage synthesis from C9 fractions from ethylene cracking with boiling range of 100～200℃ in the presence of Lewis acid as catalyst. The effect of the amount of catalyst，reaction temperature and time on the distribution and quality index of the product was investigated. Under the conditions of reaction temperature 60℃，reaction time 6 h and the amount of catalyst，1.0%（wt）complex compound of BF3 and ethylether and 1.5%（wt）AlCl3，71.1%（wt）aromatic solvent naphtha including 16.3%（wt）120#, 54.7%（wt）200# solvent naphtha and 20%（wt）petroleum resin were obtained. Adding solid alkali stopped the reaction in order to avoid producing a lot of waste water.

摘要： 以沸程在100～200 ℃乙烯副产C9馏分为原料，进行了以Lewis酸为催化剂的两段聚合法制备芳烃溶剂油工艺的研究。考察了催化剂用量、反应温度、反应时间对产品分布及质量指标的影响。结果表明：采用两段合成法，在总催化剂用量为2.5%（一段催化剂BF3•Et2O为1.0%，二段催化剂AlCl3为1.5%）、反应温度60 ℃、反应6 h的条件下得到芳烃溶剂油，总收率为71.1%，其中120#溶剂油为16.3%，200#溶剂油为54.7%。同时还可得到收率20%的石油树脂。后处理过程采用固体碱终止，没有大量废水产生。
