A gas chromatographic method for determination of extraction naphtha and benzene has been developed. The best parameters of chromatographic separation were found. Under those conditions it is possible to estimate the total concentration of all ingredients of extraction naphtha as one peak clearly separated from benzene peak. Two methods of calibration curve preparation were considered. One of them consists in preparation of calibration curve from extraction naphtha standard solutions. The other one consists in preparation of calibration curve from standard extraction naphtha vapours adsorbed on charcoal.
