Kinetics of Oxidation of Allyl Alcohol by Cr(VI)

Abstract

The kinetics of oxidation of allyl alcohol by quinaldinium chlorochromate is investigated in 40 % acetic acid -water (v/v) medium. The order with respect to oxidant and hydrogen ion concentration is found to be one and fractional with respect to substrate. The rate of the reaction is decreases with the decrease in the dielectric constant of the medium. The rate of the reaction has negligible effect with the increase of ionic strength. The reaction does not induce the polymerization of acrylonitrile. From the kinetic data obtained, the activation parameters have been calculated and a plausible mechanism has been proposed.

Sodium dodecylsulphate-catalyzed hetero-aromatic nitrogen base-promoted chromium(VI) oxidation of 2-propenol to 2-propenal in aqueous media

“…Therefore, we can say that bipy in the presence of SDS is the best promoter for the oxidation of 2-propenol by Cr(VI). A table comparing our results (Table S3) explains the selection of suitable catalysts and promoters over the other oxidants used previously in 2-propenol to 2-popenal conversion [19][20][21]37].…”

“…have been reported [15][16][17][18][19][20][21]. The reported literature followed only simple oxidation kinetics and rate law with probable mechanisms.…”

Structural Activity of Unsaturated Alcohols and Oxidation Towards Pyrazinium Chlorochromate

“…In order to avoid the versatality of these oxidants, mild Cr +6 derivatives are synthesized from heterocyclic halochromate. Kinetics of oxidation of alcohols using pyridinium chlorochromate 7 , pyridinium fluorochromate 8 , bipyridinium chlorochromate 9 , halosilanes chromium trioxide 10 , quinolinium dichromate 11 , imidazolium dichromate 12 , quinaldinium fluorochromate 13 , quinaldinium dichromate 14 and quinolinium fluorochromate 15 and benzyl triethylammonium chlorochromate 16 has been reported in the literature. The kinetics and oxidation of allyl alcohol, crotonyl alcohol and styryl carbinol using pyrazinium chlorochromate has not yet been investigated.…”
