FIELD: chemistry.
SUBSTANCE: invention relates to a method of producing 2,2'-dichlorodiethylformal. The method is realised by reacting ethylene chlorohydrin and paraformaldehyde in the presence of magnesium sulphate or magnesium chloride crystalline salt. 2,2'-dichlorodiethylformal is extracted by salting out the organic phase by saturating with magnesium salt solution. Excess ethylene chlorohydrin is then distilled from the organic phase.
EFFECT: low concentration of ethylene chlorohydrin in synthesis wastes, low expenses on recycling wastes, high environmental safety of production.
