fuels Ex: gasohol‚ a one-to-nine ratio of ethanol and gasoline Simple alcohols – Ethanol ; Poisonous to some extent Examples: Methanol is used for the manufacture of plastics and synthetic fibers. When an –OH group is substituted for one hydrogen atom in ethane‚ the resulting alcohol is ethanol. Ethanol is a good solvent for many organic solutes that cannot dissolve in water. Alcoholic beverages contain ethanol. Gasohol is a mixture of 10% ethanol and gasoline. It is used as a fuel or automobile

Consumption of alcohol by pregnant mothers may result in fetal alcohol syndrome. The long-term effects of alcohol (ethanol) consumption range from cardioprotective health benefits for low to moderate alcohol consumption in industrialized societies with higher rates of cardiovascular disease[2][3] to severe

The purpose of this experiment was to understand and become familiar with the reaction mechanisms and be able to observe and compare the product or products for each of the reactions using 13C NMR and IR. The reaction of 1-propanol (1a) with NaBr/H2SO4 was 1-bromopropane‚ the reaction of 2-pentanol (1b) with NaBr/H2SO4 was 2-bromopentane

project aims to convert food waste into butanol fuel in the most efficient and most environment-friendly manner. *A separation process will be researched and designed to first separate simple sugars from the food waste using thermophilic fungi. The challenge is to create a process that needs little energy input and produces a limited or no amount of waste and pollutant*. The next portion of this research deals with taking this sugar and converting it into butanol fuel via fermentation. This will be done

The Use of Sweeteners and the Rise in Obesity I have selected to discuss the relationship of the sweetener sugar (sucrose) between its consumption and the rise in obesity. There is a problem with the increase in sugar consumption. Sugar both drives fat storage and makes the brain think it is hungry‚ setting up a “vicious cycle‚” according Robert Lustig‚ MD‚ a UCSF pediatric neuroendocrinologist. Obesity is one of the top underlying preventable causes of death in the U.S. The rise of obesity

Abstract The antimicrobial activity of alkaloids‚ tannins‚ saponins‚ flavonoids‚ phenol and cardic glycoside present in the various parts of Chrysophyllum albidium plant were investigated. These phytochemical were determined quantitatively and tested against staphylococcus aureus‚ B. subtilis‚ pseudomonas aeruginosa‚ E. coli‚ C. tetani‚ and the fungus; candida albicans. Most the plant parts were found to contain alkaloids‚ tannins‚ phenols and flavonoids except for the absence of cardic glycosides
