Ethanol

ammonium thiocynate with 1,4-phenylene diamine appeared as homogeneous solution. White precipitate was formed immediately when the solution was filtered into the beaker containing ice cubes. Then, the precipitate was filtered again and rinsed by ethanol before being dried in the desiccator. The physical data of the synthesized bis-thiourea derivatives are shown in Table 4.1. Table 4.1: Physical data of synthesized thiourea derivatives Compound Molecular formula…

increase solubility of poorly soluble compounds. The use of co-solvents is a highly effective technique to enhance the solubility of poorlysoluble drugs.14–16 The most frequently used low toxicity co-solvents for parenteral use are propylene glycol, ethanol, glycerin, and polyethylene glycol.17-18 Dimethylsulfoxide (DMSO) and dimethylacetoamide (DMA) have been widely used as cosolvents because of their large solubilization capacity for poorly soluble drugs and their relatively low…

According to literature, older adults commonly experience decrease in memory storage. Along with that, unfortunately, they become more vulnerable victims to crime, which means they more than likely to have to provide testimony for investigation process. The current study intended to examine whether older adult have higher tendency to use their prior knowledge than younger adult and how it actually affect the accuracy and confidence of the recall result. The study employed mixed factorial design…

A process is disclosed for separating low molecular weight alcohols, especially ethanol, from aqueous mixtures  The feed mixture contains alcohol and water with an extractive solvent comprising a substituted and unsubstituted phenol having 6 carbon atoms and alcohol containing 2 to 4 carbon atoms.  In the process the upper stream contains water with minimum amount of solvent that is 99.9% and the bottom stream contains alcohol with minimum amount of water.  The temperature of the process is…

depending on what you’re in the mood for. For example, there’s beer, vodka, scotch, whiskey, wine, tequila, bourbon ext… All of the alcoholic beverages you can purchase have a different taste, and a different method of making them. “Ethyl alcohol, or ethanol, is an intoxicating ingredient found in beer, wine, and liquor. Alcohol is produced by the fermentation of yeast, sugars, and starches. It is a central nervous system depressant that is rapidly absorbed from the stomach and small intestine…

Argument Synthesis Binge drinking and alcoholism have been a long-time concern in American society. While the government and schools have made great efforts to tackle the alcohol problems by enacting laws and providing education, the situation of dysfunctional alcohol consumption hasn’t been sufficiently improved. In the essay “Drinking Games,” author Malcolm Gladwell proves to the readers that besides the biological attributes of a drinker, the culture that the drinker lives in also influences…

Evaluating the benefits and problems associated with malolactic fermentation of Merlot wines Emma Bruwer, 16122364, BSc Agric (Viticulture and Oenology), J.H Neethling Building, Victoria Street, Stellenbosch University. Rudi Scholtz, Thelema Mountain Vineyards, Helshoogte Pass, Stellenbosch. August 2015 ABSTRACT Malolactic fermentation is the conversion of harsh and acidic malic acid to a more desirable form of lactic acid in wine by Lactic acid bacteria, after the completion of alcoholic…

There was a time when talking freely about one's still is a considerable measure like expounding on one's drug stash. Even today many are led to believe that still ownership is equivalent to owning a cannabis farm but the truth is, that is hardly the case. Today owning a still is as simple as ordering a pair of socks online. All you have to do is go to www.Moonshinestills.com and have a unit shipped to your doorstep. Owners of these well-crafted devices truly appreciate utilizing if for…

by crushing up the fruit and leaving the skins in the mix for a day as the skin has natural yeast which can aid in the fermentation process. The fermentation process occurs in carbon dioxide and oxygen; the mixture is oxidised, and the sugar and ethanol react to form carbon dioxide and ethyl alcohol. The yeast will use up all the oxygen as it ferments the sugars. The process will be sugar…

complete combustion of a compound per mol is defined as the enthalpy of combustion. We can deduce this as the enthalpy of combustion of methanol (CH3OH) is -726 KJ/mol, and the enthalpy of combustion of ethanol (C2H5OH) is -1367 KJ/mol. As we can see the absolute value of the enthalpy of combustion of ethanol (i.e. 1367 KJ/mol) is much greater than the absolute value of the enthalpy of combustion of methanol (i.e. 726…
