Publikováno v: Talanta. 74:971-976

In this work, the base-catalyzed transesterification of soybean oil with ethanol was monitored on-line using mid-infrared spectroscopy (MIRS) and the yield of fatty acid ethyl esters (biodiesel) was obtained by (1)H NMR spectroscopy. The MIRS monitor

Síntese de biodiesel: uma proposta contextualizada de experimento para laboratório de química geral

Autor: Ulf Schuchardt, Roberto Rinaldi, Adriana Vitorino Rossi, Camila Martins Garcia, Letícia Ledo Marciniuk

Publikováno v: Química Nova. 30:1374-1380

The contextualized understanding of concepts in Chemistry by students from other areas is a challenging task. In this experiment, the synthesis of biodiesel is done by base catalyzed transesterification of refined soy oil with methanol at room temper

Transesterification of soybean oil catalyzed by sulfated zirconia

Autor: Camila Martins Garcia, Letícia Ledo Marciniuk, Ulf Schuchardt, Sergio Teixeira

Publikováno v: Bioresource technology. 99(14)

Two sulfated zirconias were synthesized and characterized by X-ray diffraction and infrared spectroscopy. They were used as catalysts in the alcoholysis of soybean oil and in the esterification of oleic acid. Using sulfated zirconia prepared by the s

Publikováno v: Langmuir : the ACS journal of surfaces and colloids. 21(12)

The adsorption of Congo red and tinopal CBS dyes on cellulose fibers was investigated using electronic absorption and fluorescence spectroscopies. Hydrogen bonds appear to be relevant for the dye-fiber interactions as indicated by the solvatochromism
