Modifying the Catalyst by Energising through Electron Beam Irradiation for effecting Organic Transformations in Ketones
SURESH B1 and Dr G. VANMATHI 2
Abstract
The effect of electron beam irradiation on the catalyst, 10 % Pd./C in wet and micro powder form in effecting the heterogeneous catalysis reactions like hydrogenation of Alkyl aryl ketone and Diaryl ketone was studied. The irradiation doses of 40 kGy, 60 kGy, 100 kGy, 120 kGy, 200 kGy and 250 kGy were carried out on the catalysts and the time taken for the reaction were noted. The results show that with the increase in dosage the reaction time is found to decrease progressively with a net decrease of 45 -70% relative to that of the original system without irradiation. This reduction in reaction time upon irradiation may be attributed to the increase in surface area as given by the BET surface area studies. The effect of electron beam irradiation on the catalyst was maintained even after 9 months of irradiation.
