56549-24-7 Usage
General Description
Quinolinium dichromate is a chemical compound with the formula (C9H7N)(Cr2O7). It is a red-brown crystalline solid that is used as an oxidizing agent in organic synthesis. The quinolinium cation is derived from the nitrogen heterocycle quinoline, and the dichromate anion is a powerful oxidizing agent that can facilitate a variety of oxidation reactions. Quinolinium dichromate is used in laboratories for the oxidation of alcohols and aromatic compounds, as well as for the synthesis of various organic compounds. However, it should be handled with care due to its potential for causing skin and eye irritation, as well as its classification as a hazardous substance.
Check Digit Verification of cas no
The CAS Registry Mumber 56549-24-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,6,5,4 and 9 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 56549-24:
(7*5)+(6*6)+(5*5)+(4*4)+(3*9)+(2*2)+(1*4)=147
147 % 10 = 7
So 56549-24-7 is a valid CAS Registry Number.

Kinetics and mechanism of quinolinium dichromate mediated oxidation of sugar alcohols in Bronsted acid media

Bronsted acid catalyzed oxidation of certain sugar alcohols (polyols) has been studied by quinolinium dichromate (QDC) using aqueous sulfuric, perchloric, and hydrochloric acids at different temperatures. At constant acidity, reaction kinetics revealed the second-order kinetics with a first order in [Alcohol] and [QDC]. Zucker-Hammett, Bunnett, and Bunnett-Olsen criteria were used to analyze acid-dependent rate accelerations. Bunnett-Olsen plots of (log k + Hν) versus (Hν + log [H+]), and (log k) versus (Hν + log [H+]) afforded slope values (? and ?*, respectively)?>?0.47, suggesting that a water molecule acts as a prton transfer agent in the slow step of the mechanism in the oxidation of alcohols by QDC in the presence of aqueous sulfuric, perchloric, and hydrochloric acids.
