Sodium titanate as basic catalyst in transesterification reactions
(Elsevier B.V., 2014)
Optimization of biodiesel production from castor oil
(Humana Press IncTotowaEUA, 2006)
The methylic versus the ethylic route: considerations about the sustainability of Brazilian biodiesel production
(2017-04-01)
Brazil is considered one of the world’s leading producers of biofuels given the predominance of ethanol fuel in its energy matrix. However, despite the prominence of Brazil in ethanol production, the vast majority of ...
Transesterification of rapeseed oil with ethanol: I. catalysis with homogeneous Keggin heteropolyacids
(2007)
Heteropolyacids (HPA) with Keggin structure were evaluated as homogeneous Br∅nsted acid catalysts in the reaction of rapeseed oil transesterification with methanol and ethanol at 358 K and atmospheric pressure. Rapeseed ...
Use of experimental design to investigate biodiesel production by multiple-stage Ultra-Shear reactor
(Elsevier Sci LtdOxfordInglaterra, 2011)
Mycelium-bound lipase production from Aspergillus niger MYA 135, and its potential applications for the transesterification of ethanol
(Wiley Vch Verlag, 2011-06)
The potential biotecnological applications of both constitutive and inducible lipase sources from Aspergillus niger MYA 135 were evaluated. To this end, the effect of environmental conditions on mycelium-bound lipase ...
Synthesis of fatty acid methyl esters from pomace oil catalyzed by zinc stearate: A kinetic study of the transesterification and esterification reactions
(Multidisciplinary Digital Publishing Institute, 2019-12)
In this work, the simultaneous transesterification and esterification reactions of olive pomace oil with methanol catalyzed by zinc stearate were studied. This catalyst is a crystalline solid at room temperature, but it ...
Epoxy vitrimers: The effect of transesterification reactions on the network structure
(MDPI AG, 2018-01-03)
Vitrimers are covalently crosslinked polymers that behave as conventional thermosets below the glass transition temperature (Tg) but can flow above a particular temperature, Tv > Tg, by bond exchange reactions. In epoxy ...
Niobium compounds in transesterification reactions of soybean oil: A promising use of NbCl5
(2018-04-01)
In heterogeneous catalysis, many transition metals and its derivatives, such as titanium and iron, have been vastly studied as nanoscale catalysts, but little is known about the use of niobium compounds. Being biodegradable ...
COMPARISON OF THE ACTIVITY OF TRANSESTERIFICATION OF LIPASES THROUGH THE para-NITROFENIL PALMITATO ASSAY OF TWO GRAM (-) BACILLUS ISOLATED OF SOILS
(2012-11-27)
The goal of this work was to evaluate the lipases activity of two previously isolated bacterias gram(-) with the assay of para-Nitrophenyl
Palmitate (pNPP). The experiments were carried out with dried whole-cells and ...
