Abstract

Arylmethyl halides(benzyl chloride, BZYC; benzal chloride, BZYA; benzotrichloride, BZTC) and related compounds(benzyl alcohol, BZYA; benzoyl chloride, BZOC) were determined by GC using capillary column. Detailed results are as follows. 1. Stability In methanol benzotrichloride slowly transferred to benzoyl chloride by hydrolysis(ca. 7.5% for 5 days), but the others were stable. Therefore, benzotrichloride solution should be prepared just before analysis. 2. GC analysis Tenax-GC was used to absorbent and desorption solvents were $CCl_4$ and MeOH. Arylmethyl halides were analyzed within 7.5min without interference with related compounds. The calibration curve(ca. 15-80 ppm in soln), repeatability(n=10) and the desorption efficiency were good. Limit of detection by NIOSH method was about 0.003 ppm for arylmethyl halide, respectively. To analyze arylmethyl halides and related compounds in working places GC using capillary column is anticipated to be used effectively.
