Concentrated solar radiation aided energy efficient protocol for oxidation of alcohol using biodegradable task specific ionic liquid-choline peroxydisulfate

摘要

An eco-friendly and energy efficient protocol for selective oxidation of alcohols to aldehydes/ketones has been developed by using Choline Peroxydisulfate under concentrated solar radiation (CSR). Choline and peroxydisulfate based biodegradable oxidizing task specific ionic liquid (TSIL) ChPS was synthesized, characterized, and evaluated. The oxidizing property shows excellent performance as an effective oxidant. Comparative energy calculations between conventional and CSR method show, CSR method is superior alternative pathway with high energy conservation method (similar to 90%). Incorporation of biodegradable ionic liquid and renewable energy source, makes the present protocol environmentally benign and energy efficient. (C) 2016 Elsevier Ltd. All rights reserved.
