FIELD: chemistry.
SUBSTANCE: invention relates to a method of purification of glycols from carbonyl compounds and/or their acetals by contacting glycol polymer containing sulphocathionite resin with an acidic form, and pretreated amine with the general formula (1) where R1, R2 can be the same or different and independently represent hydrogen and/or hydrocarbon group with the number of carbon atoms from 1 to 6 selected from aliphatic, aromatic and cycloaliphatic groups.
EFFECT: enables to reduce the content of carbonyl c ompounds and reduce colour indicator glycols.
