间甲乙苯是重要的基本有机化工原料和溶剂,在化工生产中应用广泛。有文献报道,它可用于制备甲醇汽油添加剂。
间甲乙苯与对甲乙苯的分离通常采用萃取精馏的方法。具体步骤如下:首先选用邻苯二甲酸二丁酯作为萃取精馏的溶剂,并将其按一定比例与原料甲乙苯混合加入到萃取精馏塔中;随后进行分离,塔顶收集高纯度间甲乙苯(≥97%),而塔釜则得到溶剂邻苯二甲酸二丁酯和对甲乙苯的混合物。塔釜物料进入溶剂再生塔,通过减压蒸馏操作回收对甲乙苯(≥92%)。分离出的溶剂邻苯二甲酸二丁酯可以循环回萃取精馏塔继续使用。

An oxidative cross-dehydrogenative coupling of isoquinolines with methyl arenes has been developed, yielding structurally diverse C1-benzyl and -benzoyl isoquinolines selectively. The direct use of readily available methyl arenes as coupling partners avoids unproductive steps for preactivating functional group installation, and is thereby attractive.
