| titleOfInvention | Method of obtaining pentaerythrite trichlorohydrin |
| abstract | FIELD: chemistry. n SUBSTANCE: pentaerythrite is subjected to interaction with chloranhydrides of organic acids C 2 -C 5 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 C 1 ÷C 3 in presence of catalysts - acids of Lewis and(or) Brensted. Obtained pentaerythrite trichlorohydrin is clarified by vacuum distillation. n EFFECT: method makes it possible to simplify the process and simultaneously increase its selectivity. n 1 tbl, 12 ex |
