Ahmad, Ejaz; Kishore Pant, Kamal; Ali Haider, M. published the artcile< Synthesis and application of TiO2-supported phosphotungstic acid for ethyl levulinate production>, Product Details of C19H34O2, the main research area is ethyl levulinate synthesis titania supported phosphotungstic acid catalyst.
The present study investigates synthesis, characterization, and application of TiO2 supported Keggin phosphotungstic acid in biorenewable transformations. In particular, 10 wt%, 20 wt%, 30 wt% and 40 wt% Keggin phosphotungstic acid was loaded over TiO2 support via wet impregnation method to prepare EPTN-1, EPTN-2, EPTN-3, and EPTN-4 catalysts, resp. After this, synthesized catalysts were tested in a microwave reactor to measure reactivity trend in order HPW > EPTN-4 > EPTN-3 > EPTN-2 > EPTN-1. A maximum 95% levulinic acid (LA) conversion was measured in the presence of 72 mg EPTN-4 catalyst, two mmol LA in 1:42 LA: EtOH (ethanol) molar ratio at 393 K in 120 min at a stirring speed of 300 rpm. No significant loss in heterogenized EPTN-4 catalyst was measured after five application cycles. A detailed characterization of synthesized catalyst showed that the Keggin structure remained intact after heterogenization.
Materials Science for Energy Technologies published new progress about Particle size. 112-63-0 belongs to class esters-buliding-blocks, and the molecular formula is C19H34O2, Product Details of C19H34O2.
