FIELD: organic chemistry.
SUBSTANCE: invention relates to the field of organic chemistry, namely to a method for purifying 2-methylimidazole, which consists in recrystallization in three stages by preparing a supersaturated solution, cooling it to 3 °C, filtering first portion of precipitated crystals, partial evaporation of water, cooling up to 3 °C, filtering the second portion of the precipitated crystals and removing water with filtration of the third portion of the precipitated crystals.
EFFECT: technical result: increased purity of the final product, technological simplification of the process.
