SEPARATION OF PSEUDOCUMENE FROM MIXTURE CONTAINING PSEUDOCUMENE

摘要

PURPOSE:To carry out the separation of pseudocumene pseudocumene-containing mixture, easily, in high selectivity and recovery, by converting the pseudocumene to the clathrate compound with metacyclophane which can be prepared a low cost. CONSTITUTION:A mixture containing pseudocumene is brought into contact with metacyclophane of formula to form the clathrate compound of metacyclophane and pseudocumene, and pseudocumene is separated from the clathrate compound after separating the clathrate compound from the reaction mixture. Pseudocumene can be separated by this process selectively even from a mixture of trimethylbenzene nucleus isomers which are difficult to be separated from each other. Pseudocumene can be separated from the clathrate compound by various methods to obtain the titled compound in high purity.
