摘要：
The separation of m-, p-, o- xylenes and m-, p- ethyltoluenes was studied on a packed column with 2,5 % of 4-[(4-chlorobenzyl)oxy]-4'-cyanoazobenzene (CBOCA) on Chromosorb W HP 100-120 mesh. The synthesis and study of the mesomorphic behaviour of CBOCA are presented. Temperature range for the separation of m-, p-, o- xylenes (in this order of elution) is 125-85 degrees C, at cooling. The best separation was achieved at about 90 degrees C The separation temperature domain of m-ethyltoluene from p- ethyltoluene is 160-85 degrees C.
