由炼油厂催气碱渣中回收得到的杂酚,其主要组份为苯酚、甲酚、二甲酚及其异构体。用一般方法分离测定这些组份十分困难,用气相色谱法直接分离测定,结果也不能令人满意。我们曾采用氢火焰离子化检测器,比较了十几种固定液,如己二酸乙二 Resorption from the refinery gas caustic residue obtained by the main components of phenol, cresol, xylenol and its isomers. The separation and determination of these components by conventional methods is very difficult and the direct separation by gas chromatography is unsatisfactory. We have used hydrogen flame ionization detector, compared a dozen fixatives, such as adipic acid ethylene
