The hydrocarbonylation reaction of ethanol with a CO/H 2 mixture assisted by Ru(acac) 3/ iodide was investigated. Bronsted and Lewis acids and iodides salt were used as homogeneous promoters. The etherification reaction…

“Green gasoline is an attractive alternative to bioethanol since it can be used in existing engines and does not incur the 30 percent gas mileage penalty of ethanol-based flex fuel,” said John Regalbuto, who directs the Catalysis and Biocatalysis Program at NSF and supported this research. “In theory it requires much less energy to make than ethanol, giving it a smaller carbon footprint and making it cheaper to produce,” Regalbuto said. “Making it from cellulose sources such as…

do etanol viii Joana Margarida Fernandes Vieira Metabolismo do etanol Abstract Of all of the abuse drugs, ethanol is one of the most accessible and with the highest consume rate by Portuguese people, maybe being one of the oldest drugs ever used by the human species, the effects of excessive consumption are well known since ancient times. Alcohol or ethanol is a legal drug marketed in society and is part of human eating habits. Alcoholism is a complex disease that…

inefficient and represents a significant loss of the energetic potential, since these lignocellulosic residues can suffer biotransformation and produce high value components, like the biofuels (ethanol). Therewith, the aim of this work was to evaluate the potential of the eucalyptus bark related to ethanol fuel production. In this way, barks from 5 commercial clones (E. urophylla x E. grandis e E. grandis) were characterized due to the chemical composition. Eucalyptus barks were…

particulate material emitted of the diesel engine. The ethanol is usually the most chosen among the alcohols for its easy production in great scale and for not being poisonous as the methanol, for example. However, the ethanol presents limited solubility in the diesel and cause undesirable reductions in the cetane number and in the viscosity of the fuel. Addictive as esters produced with the transesterification of vegetable oils can improve the ethanol solubility in the diesel and…

raw materials, study mechanism of the complex formation in solution, synthesis and characterization of the multinuclear compounds. 2.1 Materials The raw chemicals: Fe(BF4)2.6H2O, Fe(ClO4)2.6H2O, LiClO4.3H2O, C12H8N2O2(pdl), methanol and ethanol were used as obtained without further purification. The C14H10N2 (pq) and K3[Cr(C2O4)3].3H2O have been prepared based on published paper [7, 8]. 64 Djulia Onggo, Iis Siti Jahro, Fahimah Martak & Ismunandar 2.2 Instruments…

necessidade de desidratá-lo, sendo neste caso indicado ser produzido através da técnica da peneira molecular, que não incorpora nenhuma outra substância residual. A aplicação mais generalizada do álcool anidro é como combustível (motor fuel grade ethanol / MFGE), na forma de aditivo a gasolina, principalmente, melhorando a combustão, pelo aumento da octanagem e pela presença de oxigênio na molécula do álcool, reduzindo a liberação de monóxido de carbono; nos EUA, não faz tempo,…
