Shandong Minji Chemical Co.,Ltd | Updated: May 22, 2017

Chloro-pivaloyl chloride alias 3-chloro-2,2-dimethyl propionyl chloride (CPC), colorless and transparent with a stimulating liquid for pharmaceuticals, pesticide intermediates, can be used for synthetic pesticides

Colorless transparent with irritating liquid, can be dissolved in a variety of organic

Chloropivaloyl Chloride For pesticide intermediates, mainly used for the production of dioxins, Nongsi it (herbicide).

Chloropivaloyl Chloride Physical and chemical properties

Traits: colorless and transparent with irritating liquid, can be dissolved in a variety of organic

Chloro-pivaloyl chloride, in particular, the use of pivalacetic acid as the starting material, chlorination of phosphorus trichloride, synthesis of pivaloyl chloride; and then reactive distillation technology for pivaloyl chloride gas phase photocatalysis Chlorination, Chloropivaloyl Chloride and then vacuum distillation to prepare chlorpentanoyl chloride.

And the synthesis of chloropentapuryl chloride was carried out by two chlorination of pivalic acid as the raw material.Firstly, the solution of β-H chloride, chlorine gas flow rate of 13 ~ 15mL / min, reaction time 110min, (SOCl2) = 1: 1.2, the reaction time was 5h, the yield of chlorinated pivaloyl chloride was 99.2% .The synthesis route reaction time is short, the total product yield is 88.5%.

Chlorinated pivaloyl chloride

This product is colorless with irritating liquid, b.p.85 ~ 86 ℃ / 8 kpa, n20D 1.4530, the relative density of 1.199, f.p.62 ℃, soluble in ether.

The process comprises the following steps: (1) 2,2-methylpropionic acid is synthesized by the reaction of isobutanol or t-butanol and formic acid in the presence of sulfuric acid, (2) 2,2- (3) Chlorinated pivaloyl chloride was prepared by chlorinated pivaloyl chloride by interstitial liquid phase photocatalysis and rectification.
