Oxidation of chromone-3-carboxaldehyde (CCA) and substituted analogues by H,O, has been carried out in aqueous acid (HCI and H,SO, 1 and micellar media. Reaction kinetics indicated order in ICCAl as well as [H,O,I to be unity while it is a fraction ( I > n > 0) in [acid]. Reaction rates were found t
The reaction between formic acid and bromine in strongly acid aqueous media at 298 K Brz + HCOOH -2 Br-+ 2 H+ + COz was studied by absorption spectrophotometry (A = 447 nm). Reaction rates, expressed as H = -d[Brz]/dt, depend on the concentrations of HCOOH (0.3-2.4M), Br2[(2.7-13.6) X 10-3M], H+ (0.
## Abstract In aqueous H~2~SO~4~ media, chromic acid oxidation of hexitols (Dβsorbitol and Dβmannitol) to their corresponding aldohexoses in presence and absence of 2,2β²βbipyridyl (bipy) have been studied under the experimental conditions, [hexitols]~T~ β« [Cr(VI)]~T~ and [bipy]~T~ β« [Cr(VI)]~T~ (su
