Selective oxidation of rhodinol to citral using H2O2-platinum black system under microwave irradiation

Abstract

Abstract. The oxidation method utilising H 2 O 2 -Pt black system was successfully adapted in the oxidation of rhodinol which is a mixture form of geraniol and citronellol. This green oxidation found to be selectively converted geraniol to citral using conventional method. The implementation of microwave irradiation (175 Watt, 90 0 C, 30 mins) and a higher molar of H 2 O 2 further improved the conversion rate (72.6%) and selectivity (81%) as compared to the conventional method.
