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.
The hydroxyl group of ethanol is its main point of interest in chemistry. Ethanol; is a flammable, colorless, slightly toxic chemical compound, and is best known as the alcohol found in alcoholic beverages. In common usage, it is often referred to simply as alcohol.
The distinction between alcohol and ethanol is pretty simple. Ethanol, or ethyl alcohol, is the only type of alcohol that you can drink without seriously harming yourself, and then only if it hasn't been denatured or doesn't contain toxic impurities.
Ethanol is the alcohol that is found in our alcoholic beverages like beer, whiskey, and brandy. In alcoholic beverages, the ethanol is produced from the process of fermentation, which is the chemical breakdown of sugar by yeast.
Even though ethanol is very commonly used, it is a dangerous chemical. As previously mentioned, it is highly flammable; as such, it has exact flash points which are important to know when using it. While ethanol is consumed when drinking alcoholic beverages, consuming ethanol alone can cause coma and death.
The only type of alcohol that humans can safely drink is ethanol. We use the other two types of alcohol for cleaning and manufacturing, not for making drinks. For example, methanol (or methyl alcohol) is a component in fuel for cars and boats.
Toxicology and toxicokinetics. Distilled spirits (whisky, gin, vodka) usually contain 40–50% ethanol; wines contain 10–12% ethanol and beer ranges from 2–6% ethanol, while standard lager contains about 4% ethanol.
Topically applied ethanol (e.g. in the form of cosmetics or hand disinfectants) on un-lacerated human skin will not cause acute or systemic toxic effects, which can only occur if applied on damaged skin especially in children.
Steps for Making Ethanol
There are two primary pathways to produce cellulosic ethanol: biochemical and thermochemical. The biochemical process involves a pretreatment to release hemicellulose sugars followed by hydrolysis to break cellulose into sugars.
It is easily synthesized from the reaction of propylene with sulfuric acid, followed by hydrolysis. In some cases the hydration of propylene is carried out in one step, using water and a catalyst at high pressure. Isopropyl alcohol is mixed with water for use as a rubbing-alcohol antiseptic.
Manufacturing processes. Isopropyl alcohol has been called the first petrochemical (IARC, 1992). It can be prepared via three different methods: indirect hydration of propylene, direct hydration of propylene, and catalytic hydrogenation of acetone.
Alcohol has been used as an antiseptic as early as 1363, with evidence to support its use becoming available in the late 1800s. It is on the World Health Organization's List of Essential Medicines.
There are a wide variety of alcohol beverages and can be categorized into 3 main types: wine, spirits, and beer. Certain alcoholic drinks contain more alcohol than others and can cause drunkenness and alcohol poisoning more quickly and in smaller amounts.
Ingesting any hand sanitizer made with either ethanol or methanol can cause symptoms that appear very similar to general alcohol poisoning, including nausea, vomiting, headache, abdominal pain, decreased coordination and blurry vision.
Ethyl alcohol is a great choice for cleaning electronics in the laboratory because it's inexpensive, mineral-free, and evaporates quickly. While ethanol isn't a strong solvent, it is typically sufficiently powerful to clean sensitive electronics which may have accumulated light layers of corrosion or dirt.
Ethyl alcohol and ethanol are two terms used to name the same chemical compound. The only difference between ethyl alcohol and ethanol is that ethyl alcohol is the common name given for the compound CHOH whereas ethanol is the IUPAC name given for the ethyl alcohol.
The main difference between isopropyl alcohol and rubbing alcohol is the concentration. The concentration of isopropyl alcohol is 100%, while the concentration of rubbing alcohol is less because of the addition of water. Otherwise, the two liquids have similar properties.
Rubbing alcohol can help clean and disinfect hard surfaces. It is effective against most, but not all, pathogens. The main ingredient in rubbing alcohol is isopropyl alcohol (IA). Most rubbing alcohols contain about 70% IA, but the amount can range from 60% to 99%, depending on the product.
American Screening LLC, located in Shreveport, Louisiana, recalled 153,336 total units of the 70% ethyl alcohol gel. The affected hand sanitizer include the expiration dates of May 21, 2022 and May 24, 2022 for black capped bottles, and there are no lot numbers or expiration dates for clear-capped bottles.
