OBJECTIVE: To establish a method for the determination of several residual organic solvents in benzyl chloride regimen. Methods: Capillary gas chromatography was used for the determination of residual solvents in chlorobenzyl chloride by PEG 20M quartz capillary column (0 2 5mm × 30m) and temperature programmed technique. Results: The established chromatographic method had good resolution for the solvent under test. The linearity was good within the investigated concentration range. The recoveries of the solvents ranged from 98.4% to 105.1% with the detection limit of 1-2ng. Conclusion: The chromatographic method established in this experiment is sensitive and accurate and suitable for the determination of residual organic solvents in benzyl chloridation.
