Through IR analysis, the main component in group II was identified as dialkyl-benzene, while in Group III was monoalkyl-benzene as well as dialkyl-tetralin and indane ( DTI). 通过红外光谱的鉴定,大致确定第Ⅱ族组分主要为二烷基苯,第Ⅲ族组分主要为单烷基苯和少量的二烷基茚满、萘满(DTI)。
In general, benzylic alcohols react with terminal alkenes to afford trisubstituted alkenes, and the reaction with 1,2-disubstituted and trisubstituted alkenes affords indane derivatives. 一般而言,苄型醇和端烯反应生成三取代烯烃;而1,2-二取代、三取代烯烃的反应生成2,3-二氢茚类化合物。
It is significant in the purification of 1,2,3-trimethylbenzene from 190# solvent oil, however, because the boiling points of two highest content components-1,2,3-trimethylbenzene and indane are very close, they are difficult to separate by conventional distillation. 从溶剂油中提纯连三甲苯意义重大,但其中含量最多的连三甲苯和茚满之间沸点非常接近,普通的精馏分离方法很难达到分离要求。
