Studies of Oxidation of Aromatic Secondary Alcohol By Ion Exchange Resin Tusion-421 : A Kinetic Investigation
Journal Title: IOSR Journal of Applied Chemistry (IOSR-JAC) - Year 2018, Vol 11, Issue 7
Abstract
Oxidation of organic compounds is quite important from synthetic and technological view points. Many of the industrially important organic compounds like aldehydes, ketones, acids, etc. can be produced by the oxidation of related substrate by the use of suitable oxidizing agents. The kinetics of the oxidation of 1- Phenylethanol (PE) by PS-Chromate has been followed by monitoring the constant in the absorbance of reaction intermediate. The reaction followed by zero order behavior, being zero order in each reactant. The rate of reaction constant with increase in weight of oxidant, concentration, temperature and dielectric constant of the solvent. A free radical scavenger affects the reaction rate. The stiochiometry has been found to be 1mol PE: 1mol of Chromate. Thermodynamic parameters evaluated are [Ea] = 85KJ mol-1 , [∆H# ] =53 KJ mol-1 , [∆S# ] = -70 JK mol-1 , [∆G# ] =306KJ mol-1 , and [A] =3.6 x 10-5 s -1 results under pseudo zero order conditions are in agreement with the rate law. The object of the present study is the oxidation of aromatic secondary alcohol by ion exchange resin by Tulsion-421.
