Article Synopsis
- Researchers investigated using Rhizopus oryzae lipase immobilized in a hydroxylpropyl methyl cellulose and polyvinyl alcohol blend to synthesize citronellol esters in supercritical carbon dioxide (Sc-CO2).
- The optimization of reaction parameters increased the citronellol acetate yield from 11% to 91%, showcasing the efficiency of the immobilized lipase compared to the free form.
- The method offers advantages like lower biocatalyst loading, reduced reaction temperature and pressure, and successful recycling of the immobilized biocatalyst for multiple reactions.
A simple and convenient methodology for selective sulfonation of aromatic compounds using sulfuric acid under sonication is described. The present methodology shows a considerable enhancement in the reaction rate along with improved selectivity compared with the reactions performed under silent conditions. The effect of various parameters such as agitation speed, sulfuric acid concentration, and temperature on reaction system have been investigated and are explained on the basis of ultrasonically generated cavitational effects.
