Abstract
For the identification of gas chromatographic eluents, pyrolysis gas chromatography has been studied.
At this first stage, individual alkylbenzene was put into the pyrolysis tube (stainless steel, 4.8 mm i. d. × 83 mm, filled with 0.77 ml alumina) followed by a separation column, and, after the examination of the experimental conditions including pyrolysis temperature, carrier gas flow rate, etc., the pyrograms of C6C10 alkylbenzenes were obtained. It was made clear that the carbon-carbon bond dissociation energy of the side chain of alkylbenzene had an intimate correlation with pyrolysis products, and that the higher the molecular weight was, the larger the decomposition which followed.
