Problems solved by technology
The preparation method of trichloroacetone is usually the method for the direct chlorination of acetone. In the existing technology, due to the poor selectivity of chlorination, the yield is low. In the chlorination product, except trichloroacetone, it also contains monochloroacetone, Dichloroacetone, tetrachloroacetone, pentachloroacetone and hexachloroacetone
[0003] In order to prevent the leakage of toxic substances during the dechlorination process, the existing dechlorination devices all use airtight containers for reaction, and stir and mix through an external magnetic stirring device. The intake pipe placed in the container collides, and the stirring effect is not good, and the existing closed container device is not suitable for batch dechlorination treatment, and the dechlorination efficiency is low. Therefore, we propose a hydrodechlorination of trichloroacetone Apparatus and method thereof

Description
technical field [0001] The invention belongs to the technical field of chemical purification, and in particular relates to a hydrodechlorination device for trichloroacetone and a method thereof. Background technique [0002] Trichloroacetone is an important industrial raw material. Trichloroacetone, especially high-purity trichloroacetone, has an extremely wide range of uses and can be used in the synthesis and research of anti-HIV drugs, imidazole heterocyclic compounds, polycyclic or bridged ring compounds . The preparation method of trichloroacetone is usually the method for the direct chlorination of acetone. In the existing technology, due to the poor selectivity of chlorination, the yield is low. In the chlorination product, except trichloroacetone, it also contains monochloroacetone, Dichloroacetone, tetrachloroacetone, pentachloroacetone and hexachloroacetone. Among them, tetrachloroacetone, pentachloroacetone and hexachloroacetone are insoluble in water, and after...
