The Suzuki−Miyaura cross-coupling of p-tolylboronic acid 1 and iodobenzene 2 to form 4-phenyltoluene 3 in the presence tetrabutylammonium methoxide 4 immobilized catalyst PdEnCat as stationary phase has been carried out continuous-flow mode using conventional organic supercritical carbon dioxide solvent systems between temperatures 55 120 °C pressures up 250 bar. Laboratory-scale reaction studies have undertaken on a 5 cm × 4.5 mm i.d. column packed with Pd(II)EnCat 40 [Lee et al., Chem...

Abstract Free fatty acids are an important intermediate for several industrial applications, particularly production of biodiesel via methanolysis. The use subcritical water as both solvent and reactant the hydrolysis vegetable oil to generate has recently been proven be a successful medium without employing acid or alkali catalysts, while allowing simple process high yield. Continuous flow sunflower in obtain FFA was investigated tubular reactor at 10 20 MPa, 270 350°C water/oil ratios...

Converting glycerol, a by-product from biodiesel production into useful products and energy could contribute to positive life cycle for the process. One kg of glycerol is produced every 10 has potential be used as source H2, syngas or CH4 by an appropriate conversion Catalytic Supercritical Water Gasification (CSCWG) processing crude solutions one such viable option. Above its critical point [>221 barg, >374 °C], properties water, low relative permittivity high ionic product make it capable...

In this paper, biodiesel production from waste frying oils was investigated with zinc aluminate (ZnAl2O4) as a heterogeneous catalyst, synthesised by the combustion of urea aluminium nitrate and nitrate. The transesterification studied at temperatures between 60 200 °C, in an alcohol:oil molar ratio 40:1, 2 h reaction time, stirring 700 rpm different catalyst amounts (from 1% to 10% based on oil weight). yield analyzed gas chromatographer. Synthesised recovered were characterized for their...

Trata-se um relato experiência estudantes do curso enfermagem Universidade Estado Minas Gerais. Os sete eventos on-line LAUE foram conduzidas por cinco fundadores, dez efetivos três professoras ocorreram entre os meses junho setembro 2020. conteúdo conduzidos professores profissionais área saúde com expertise na temática....

Extraction tests were undertaken using supercritical carbon dioxide at 100 bar and 313 K on the model herb Origanum vulgare L. ssp. virens (Hoffm. et Link) letswarrt in presence of water. An increase extraction degree essential oils was noted when water added either a discontinuous or continuous manner. The largest observed discontinuously concentration 80% w/w. addition also led to reduction yield coextracted waxy material. In contrast, an from plant matrix largely due interactions between...

This article presents the results of oxidation at supercritical conditions a nonbiodegradable and highly stable nitrogen containing heterocyclic organic compound (quinoline) over mixed catalyst in tubular fixed-bed reactor. The effect operating namely temperature, pressure, oxygen concentration, initial quinoline concentration were studied to evaluate their on removal compound. showed that catalytic reaction depended strongly temperature pressure; nevertheless it was very efficient milder...
