FIELD: chemistry.
SUBSTANCE: pentaerythrite is subjected to interaction with chloranhydrides of organic acids C2-C5 of normal and iso-structure. Reaction is realised at temperature 150-200°C, preferably 170-190°C, in closed reactor with obtaining monoether of pentaerythrite trichlorohydrin with the following removal of carboxyl group by alkaline or acid hydrolysis or transesterification with alcohols C1÷C3 in presence of catalysts - acids of Lewis and(or) Brensted. Obtained pentaerythrite trichlorohydrin is clarified by vacuum distillation.
EFFECT: method makes it possible to simplify the process and simultaneously increase its selectivity.
