Grain alcohol

Zemplen helped his students in many ways. I remember an occasion in the difficult postwar period. The production of the famous Hungarian salami, interrupted by the war, was just in the process of being restarted for export. The manufacturer wanted a supportive analysis from the well-known professor. Zemplen asked for a suitable sample of some hundreds of kilograms, on which the whole institute lived for weeks. When it was gone he rightly could offer an opinion that the product was quite satisfactory. After the war, grain alcohol was for a long time the only available and widely used laboratory solvent, and, not unexpectedly, it also found other uses. Later, when it was denatured to prevent human consumption, we devised clever ways for its purification. The lab also manufactured saccharine, which was... 

Wash with rectified spirits (azeotrope of Ethanol + water, also known as "grain alcohol") to dissolve the Safrole, leaving the Phellandrene behind. Of course, one should use only the amount of alcohol necessary to dissolve the expected yield of Safrole. 1 1 seems to work, but could be an excessive amount. 

Ethanol water is a solution of denatured grain alcohol. Its main advantage is that it is nontoxic and thus is widely used in the food and chemic industry. By using corrosion inhibitors it could be made non-corrosive for brine service. It is more expensive than methanol water and has somewhat lower heat transfer coefficients. As an alcohol derivate it is flammable.

Write the Lewis structure of each of the following organic compounds (a) ethanol, Cl IjCLLOH, which is also called ethyl alcohol or grain alcohol (b) methylamine, CH3NH2, a putridsmelling substance formed when flesh decays (c) formic acid, HCOOH, a component of the venom injected by ants. 

A major part in the language of chemistry is in learning the names of the chemicals (nomenclature). Many chemicals, particularly the more common ones, are known by several different names. For example, the chemical CH3CH2OH has the systematic name ethanol. The publication Chemical Abstracts (American Chemical Society) also uses the name ethanol. The historical or common name is ethyl alcohol or grain alcohol. A nickname for it is just alcohol, and there are various tradenames, depending on the manufacturer. For example, the Fastman Company sells it under the name of Tecsol . Fven trained chemists have trouble with nomenclature, which makes the use of and need for written chemical formulae common among chemists. 

Also called ethyl alcohol, grain alcohol, and industrial alcohol)... 

The simplest alcohol is methanol, CH,OH, also called methyl alcohol in a less systematic system of naming. Methanol is also known as wood alcohol. Ethanol, CH3CH2OH, also known as ethyl alcohol or grain alcohol, is the principal constituent of intoxicating beverages. Other alcohols of importance are included in Table 21-5. Note that the systematic names of alcohols characteristically end in -ol.

Often, these sugars are from grains => grain alcohol . 

Impurities can be either soluble or insoluble. For example, the material that gives cheap wine its unique bouquet is soluble in the alcohol. If you distill cheap wine, you get clear grain alcohol separated from the impurities, which are left behind in the distilling flask. 

Ethanol, or grain alcohol, is an alcohol fuel widely used as automotive fuel. It can be made from a variety of feedstocks, mainly grains, forest resides, and solid waste. It can be used in its pure form, but is more widely used in a blended form. Gasoline blends (90% gasoline/10% ethanol) have been widely used in many areas of the country. Ethyl tertiary butyl ether (ETBE) is a feedstock for reformulated gasoline based on ethanol. 

Fermenting grains with yeast produces a grain alcohol. The process also works with other biomass feedstocks. In fermentation, the yeast decomposes carbohydrates which are starches in grains, or sugar from sugar cane juice into ethyl alcohol (ethanol) and carbon dioxide. The process breaks down complex substances into simpler ones. 

Ethanol (ethyl alcohol made from grains) Ethanol (C H OH) is one of many types of alcohol. Grain alcohol can be produced by fermentation of agricultural waste, corn, or other grains. Another method is the hydration of ethylene the reaction of water with ethylene (C H ), a reaction in which the alcohol molecule is formed the water is then split off by heat.

The additives used in oxygenated gasoline are alcohols and ethers, the most common of which are ethanol (ethyl alcohol grain alcohol) and methyl t-butyl ether (MTBE). Two less commonly used additives are ethyl t-butyl ether (ETBE) and t-amyl methyl ether (TAME). The chemical structures of these four additives are shown in the diagram on page 24. 

There is evidence that the Greeks, Egyptians, Hebrews, Japanese, Chinese, and Russians made alcoholic beverages thousands of years ago. Alcohol (ethanol, ethyl alcohol, and grain alcohol) is produced by yeast fermentation of sugar in fruits and grains to make wine, beer, or a variety of alcoholic spirits, including gin, vodka, and scotch.
