2-Pentanone 2,4-dinitrophenyl hydrazone is a chemical compound derived from 2-pentanone, an organic ketone, and 2,4-dinitrophenyl hydrazine, a reagent used in the formation of hydrazones. 2-Pentanone 2,4-dinitrophenyl hydrazone is formed through a condensation reaction between the carbonyl group of 2-pentanone and the hydrazine group of 2,4-dinitrophenyl hydrazine, resulting in the formation of a hydrazone linkage. The compound is characterized by its yellow crystalline appearance and is used in various analytical applications, such as the detection and identification of ketones in organic chemistry. It is important to note that 2,4-dinitrophenyl hydrazones are generally sensitive to light and heat, and should be stored and handled with care to maintain their stability and integrity.

1636-82-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1636-82-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,3 and 6 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1636-82:
(6*1)+(5*6)+(4*3)+(3*6)+(2*8)+(1*2)=84
84 % 10 = 4
So 1636-82-4 is a valid CAS Registry Number.

Kinetics and Mechanism of Oxidation of Alcohols by Ceric Ammonium Nitrate

Mathur, Dwarka, L.,Agarwal, Anupma,Banerji, Kalyan K.

, p. 519 - 522 (2007/10/02)

The main product of the oxidation of secondary alcohol by ceric ammonium nitrate is the corresponding ketone.The reaction is of first-order with respect to the oxidant but exhibit a Michaelis-Menten type kinetics with respect to the alcohol.The formation constants of the alcohol-CeIV complex and its thermodynamic parameters have been calculated.The rate of decomposition of the complex and the activation parameters have also been evaluated.The rates of decomposition of the complex correlate with Taft's ?* values with a low negative reaction constant.The oxidation induced polymerisation of acrylonitrile.The retardation of rate with increasing acidity has been explained on the formation of kinetically inactive protonated alcohol.The protonated constants for the various alcohol have been calculated.The presence of a small primary kinetic isotope effect, kH/kD = 2.3, confirms that the rate-determining step involves a C-H bond rupture in a non-symmetrical transition state.
