Abstract

Abstract: The thermostat of the gas chromatograph is a well stirred liquid bath, in which the column temperature is to be kept within±0.01℃.The infinite dilution activity coefficients of C₆~C₈ aromatics, namely, benzene,toluene,ethylbenzene,p-xylene,m-xylene and o-xylene in aromatic derivative, dibenzyl, diphenylmethane, diphenylacetylene, 4-benzylbiphenyl, benzophenone, dibenzylether, diphenylamine, N, N-diphenylformamide and diphenylsulphoxide, all of them contained two or three aromatic rings have been measured.

Key words: Infinite dilution activity coefficient, Solubility parameter, Interaction constant
