METHOD OF DETERMINING LOWER ALKYLMERCAPTANS Russian patent published in 1998 - IPC

Abstract RU 2117942 C1

FIELD: analytical methods. SUBSTANCE: sample of object to be examined is transferred into hydrocarbon solvent, sample solution is treated by fluorine- containing reagent and subjected to gas-liquid chromatography analysis. As hydrocarbon solvent and reagent, hexane and perfluorovaleryl chloride are, respectively, used, and treatment of sample is carried out in presence of pyridine at volume ratio hexane/ perfluorovaleryl chloride/pyridine 1:(0.01-0.02):(0.005-0.01). EFFECT: improved analytic accuracy. 3 dwg, 6 tbl
