BATCH, SEMI-CONTINUOUS OR CONTINUOUS HYDROCHLORINATIONOF GLYCERIN WITH REDUCED VOLATILE CHLORINATED HYDROCARBON BY-PRODUCTS AND CHLOROACETONE LEVELS |
摘要 |
The present invention relates to a process for converting a multihydroxylated-aliphatic hydrocarbon or ester thereof to a chlorohydrin, by contacting the multihydroxylated-aliphatic hydrocarbon or ester thereof starting material with a source of hydrogen chloride at superatmospheric, atmospheric and subatmospheric pressure conditions for a sufficient time and at a sufficient temperature, preferably wherein such contracting step is carried out without substantial removal of water, to produce the desired chlorohydrin product; wherein the desired product or products can be made in high yield without substantial formation of undesired overchlorinated byproducts; said process carried out without a step undertaken to specifically remove volatile chlorinated hydrocarbon by-products or chloroacetone, wherein the combined concentration of volatile chlorinated hydrocarbon by-products and chloroacetone is less than 2000 ppm throughout any stage of the said process.
