Pivaloyl Chloride In The Plastics Industry For The Production Of Initiator And So On

Pivaloyl chloride (pivaloylchloridl) is the main raw material for the production of trihydric acid, its quality directly affects the quality and yield of trihydric acid, Pivaloyl Chloride so the quality of pivaloyl chloride detection of trihydric acid production is very In general, the detection of pendoyl chloride is the appearance of detection and content detection. Appearance testing requirements of the standard colorless transparent liquid.

The chlorinated pivaloyl chloride was synthesized by the gas phase reaction of pivaloyl chloride as the raw material and the gas phase reaction device of the substrate β-H. Pivaloyl Chloride The results showed that when the flow rate of chlorine was 13 ~ 15cm3 / min and the reaction time was 130min, the reaction temperature was increased from 104.5 ° C to 166 ° C, and the highest yield was 85 %.

Pivaloyl chloride is also known as pivaloyl chloride, tert-amanoyl chloride, Pivaloyl Chloride trimethyl acetyl chloride, 2,2-dimethyl propionyl chloride.
