Precise Coulometric Titrations of Potassium Dichromate
This paper reports results of a continuing investigation to evaluate coulometric methods of analysis and to develop highly precise and accurate analytical methods for important materials, based upon this technique. Earlier papers described the coulometric titrations of acids and bases [1] 1 and of halides [2]. The present research is concerned with a typical oxidation-reduction titration, the a...
متن کاملSelective Oxidation of Cyclohexane to Cyclohexanone
Cyclohexane oxidation is an important commercial reaction for the preparation of cyclohexanol and cyclohexanone, which are intermediates in the production of adipic acid and caprolactam respectively. These intermediates are important in the manufacture of nylon-6 and nylon-6,6 polymers (Yuan et al 2006 and Shylesh et al 2007). In addition, cyclohexanol and cyclohexanone are also used as solvent...
متن کاملQuinolinium Dichromate Oxidation of Aliphatic Aldehydes: A Kinetic Study
Kinetic data on the rates of quinolinium dichromate oxidation of a series of aliphatic aldehydes have been determined and discussed with reference to aldehyde hydration equilibria. Kinetic results support a pathway proceeding via a rate-determining oxidative decomposition of a chromate ester of an aldehyde hydrate. A cyclic transition state is suggested; being a Hückel-type system (4n + 2), thi...
متن کاملGrowth Mechanism and Crystal Form of Potassium Dichromate
The structure of potassium dichromate (P , Z = 4) consists of two layers parallel to (001), between which no crystallographic symmetry relation exists. These layers are nearly coincident with each other when rotated through 90° about c*. One question remained unanswered: do the crystals grow parallel to {001} with d(002) or d(001) layers? The pseudo-fourfold axis does not run parallel to a crys...
متن کاملGreen Catalytic Oxidation of Cyclohexanone to Adipic Acid
Synthesis of adipic acid by catalytic oxidation of cyclohexanone with 30% hydrogen peroxide in the presence of sodium tungstate catalyst can be well performed under reflux temperature. The adipic acid isolated yield reaches to 82.1%, and the purity of the product is also very high. The catalytic oxidation reaction takes place without any organic solvent and phase-transfer agent. The effects ove...
