What is ethanol PDF?
Ethanol with the molecular formula C 2 H 6 O is a clear, colorless, volatile liquid with a pleasant smell made by fermentation of sugar. Ethanol is one of many kinds of alcohol and is the only type of alcohol that can be consumed.
What are the main uses of ethanol?
Ethanol is used in the manufacture of drugs, plastics, lacquers, polishes, plasticizers, and cosmetics. Ethanol is used in medicine as a topical antiinfective, and as an antidote for ethylene glycol or methanol overdose.
What is meant by 95% ethanol?
1) 95% (95.6%) Ethanol This is the highest concentration of ethanol you can get by distillation because 95.6% ethanol is an azeotrope, which means the vapor state has the same ethanol-to-water ratio as the liquid state.
How do you explain ethanol?
Ethanol is an important industrial chemical; it is used as a solvent, in the synthesis of other organic chemicals, and as an additive to automotive gasoline (forming a mixture known as a gasohol). Ethanol is also the intoxicating ingredient of many alcoholic beverages such as beer, wine, and distilled spirits.
What is the common name for ethanol?
Ethanol is also called ethyl alcohol, grain alcohol or drinking alcohol. Ethanol is also known as EtOH and is it a volatile flammable, colorless liquid. Ethanol, C2H5OH, is a colorless, clear, and volatile liquid classified as an alcohol.
How ethanol is produced?
Most ethanol in the United States is produced from starch-based crops by dry- or wet-mill processing. Nearly 90% of ethanol plants are dry mills due to lower capital costs. Dry-milling is a process that grinds corn into flour and ferments it into ethanol with co-products of distillers grains and carbon dioxide.
What are three uses of ethanol?
Ethanol is used extensively as a solvent in the manufacture of varnishes and perfumes; as a preservative for biological specimens; in the preparation of essences and flavorings; in many medicines and drugs; as a disinfectant and in tinctures (e.g., tincture of iodine); and as a fuel and gasoline additive (see gasohol).
What is the difference between 95% ethanol and absolute ethanol?
Absolute ethanol is hygroscopic (it attracts water), so don’t expect it to remain ‘100%’ ethanol for long if it’s left uncapped. Denatured ethanol (either 95% or absolute) contains additives (such as methanol and isopropanol) that render it unsafe to drink, and therefore exempt from certain beverage taxes.
What is the difference between alcohol and ethanol?
Ethanol and alcohol are the same, and they have the same physical and chemical properties. Ethanol is a type of alcohol, and the two are formed by the fermentation of glucose by enzymes in yeast. Alcohol is any chemical having a ‘“ OH functional group.
