FIELD: chemistry.
SUBSTANCE: invention relates to analytical chemistry and specifically to a method for preparing samples of oil-field reagents. Method of preparing samples of oil-field chemicals for determining organochlorine compounds and organically bound chlorine involves separating salts of quaternary ammonium compounds to eliminate the effect of products of their thermal decomposition, wherein analyzed sample, polar and non-polar solvents are extracted in equal proportions, extraction of mixture with transition of quaternary ammonium compounds to polar phase, and organochlorine compounds in a nonpolar phase with subsequent extraction of an aliquot of an extract of a nonpolar solvent for analysis.
EFFECT: high accuracy and reliability of determining quantitative content of organochlorine compounds present in reagents.
