FIELD: analyzing or investigating of materials.
SUBSTANCE: method comprises extracting methanol from the condensate by means of distillated water by setting 500-100ml of condensate in the separating funnel, adding 50-100 ml of distillated water to the condensate, mixing the liquids for 20 min, allowing the mixture to settle out to separate the water from methanol, and analyzing the extractant by means of method of infrared spectrometry.
EFFECT: reduced time of and simplified procedure of analyzing.
