Chloro-pivaloyl Chloride Is A Pharmaceutical And Other Chemical Synthesis

Shandong Minji Chemical Co.,Ltd | Updated: Oct 09, 2017

Chloro-pivaloyl chloride is a colorless transparent with a stimulating liquid, soluble in a variety of organic solvents, b.p.85 ~ 86 ℃ / 8 kpa, n20D 1.4530, the relative density of 1.199, f.p.62 ℃, dissolved in ether.

Chloropivaloyl Chloride Is an intermediate of herbicides and oxytetracycline.

Used as medicine, pesticide intermediates, can be used for the synthesis of pesticides maltitol, is medicine, Chloropivaloyl Chloride pesticides and other chemical synthesis.

The preparation method is in the reaction flask by adding 3-chloropuranoic acid and thionyl chloride, heating reaction, after the end of the reaction of the remaining thionyl chloride, and then distilled under reduced product.

A process for the preparation of chlorpentanoyl chloride, and more particularly, relates to a process for the synthesis of pivaloyl chloride using chlorobutanyl chloride in the presence of isobutanol or t-butanol and formic acid as starting materials. Chloropivaloyl Chloride The production process technology adopted in the invention has the advantages of simple process, low production temperature, low pressure, easy operation, easy control and good quality and stability, high yield, greatly reducing the production cost and producing the scale Provided a guarantee. In the case of

(1) 2,2-methylpropionic acid is synthesized by the reaction of isobutanol or t-butanol with formic acid in the presence of sulfuric acid, (2) 2,2-bis (3) chlorinated pivaloyl chloride was prepared by chlorinated pivaloyl chloride by interstitial liquid phase photocatalysis, Chloropivaloyl Chloride and the chlorinated pivaloyl chloride was prepared by chlorination of phosphorus pentachloride.
