Introduction
Things that appear to be the same might sometimes be quite different. Ethanol and methanol are examples of this. These two things not only sound the same, but they also appear alike if poured into two different glasses. However, if you did anything else with them, or simply got too close to the open glasses, you’d quickly see that ethanol and methanol have significant differences, and that mistaking one for the other can be disastrous.
Methanol
Methanol, also known as methyl alcohol, is a chemical compound that has the formula CH3OH. A methyl group that is linked to a hydroxyl group is abbreviated as MeOH in most cases. Methanol is a polar solvent, which means it dissolves in water. Methanol is also referred to as wood alcohol in some circles. The origin of this name can be traced back to the destructive distillation of wood, which produced methanol in the past. In today’s world, the majority of methanol is produced industrially through the hydrogenation of carbon monoxide.
Methanol is composed of a methyl group attached to a polar hydroxyl group. Methanol is a colourless liquid. Methanol is produced in large quantities, with annual production reaching more than 20 million tonnes. Methanol is a chemical compound that is used as a precursor to other industrial chemicals. For example, methyl benzoate, formaldehyde, methyl tert-butyl ether, acetic acid, anisole, peroxy acids, and a host of other chemicals are included in this category, as well as a variety of more specialised chemicals.
Methanol’s Physical Characteristics
Methanol is a clear, colourless, and flammable liquid that is light, volatile in nature, and colourless.
It has a distinct alcoholic odour that is similar to that of ethanol, and it is toxic.
Methanol has a molecular weight of 32.04 g/mol and a molar mass of 32.04 g/mol.
Methanol has a density of 729 kilograms per cubic metre.
Methanol has a boiling point of 64.7 degrees Celsius.
Methanol has a melting point of 97.6 degrees Celsius.
Methanol’s Chemical Characteristics (Reactions of Methanol)
Methanol Oxidation Reaction: The oxidation reaction of Methanol is used in the production of formaldehyde, which is an industrially and commercially important chemical compound. A chemical reaction occurs when Methanol is allowed to react with nascent oxygen in the presence of a catalyst such as potassium dichromate in an acidic medium. The result is the formation of formaldehyde and water. The following is a description of the reaction’s mechanism:
CH3OH + O →HCHO + H2O
Ester formation is a chemical reaction.
In the presence of a carboxylic acid, the reaction between alcohol and carboxylic acid results in the formation of another class of organic chemistry compounds, known as esters. When Methanol reacts with acetic acid, an ester (methyl ethanoate) is formed, as shown in the following example:
CH3OH + CH3COOH →CH3COOCH3
Methanol has a variety of applications (CH3OH)
After being converted to formaldehyde, it is used in the production of polymers.
It is employed in the production of hydrocarbons.
Methylene ethers, methylamines, and methyl chlorides are all produced from it as precursors.
A fuel for internal combustion engines, it is made from a variety of sources.
It is a highly effective energy carrier.
It is employed in wastewater treatment plants.
It is used as a fuel in boating stoves and camping stoves, among other things.
It is employed as an antifreeze agent.
It is employed in the production of chemical compounds.
Purified methanol is used in the production of perfumes, resins, and pharmaceuticals, among other things.
Ethanol
Ethanol is a by-product of plant fermentation that is used as a fuel. Natural ethanol production occurs as a result of the fermentation of sugars by yeasts. It can also be produced through petrochemical processes, such as the hydration of ethylene, which are described below. Ethanol has a variety of medical applications, including disinfectant and antiseptic properties. It can be used as a chemical solvent, in the synthesis of organic compounds, and as an alternative fuel source, among other applications.
Formula for Ethanol
Ethyl alcohol, grain alcohol, drinking alcohol, spirits, and simply “alcohol” are all names for the substance. It is a chemical compound that is made up of organic elements. A type of alcohol with the chemical formula C2H6O, ethanol is a substance that contains carbon dioxide and water. Ethanol’s chemical formula can also be written as CH3CH2OH,C2H5OH, with an ethyl group linked to a hydroxyl group as the first two letters.
EtOH is a common abbreviation for the chemical formula. Ethanol is a colourless liquid with a slight characteristic odour that is volatile in nature, flammable, and combustible. A psychoactive substance, recreational drug, and the active ingredient in alcoholic beverages, ethanol is also known as ethyl alcohol.
The Characteristics of Ethanol
Ethanol is always a liquid when kept at room temperature. Ethanol has a melting point of 156 degrees Celsius and a boiling point of 351 degrees Celsius. Ethanol is one of the most active ingredients in all alcoholic beverages, making it one of the most popular choices. It is also used in the production of various medicines, such as cough syrups, tonics, and tincture iodine, due to the fact that it is a very effective solvent. Any amount of ethanol is completely soluble in water in any proportion.
Furthermore, even a small amount of pure ethanol can be hazardous if consumed in large quantities. Drinking alcohol for an extended period of time may result in disease and negative health consequences. In the presence of monatomic oxygen, ethanol degrades to form ethanoic acid. Because ethanol burns, it is considered a flammable substance. When it is burned in the presence of oxygen, it produces carbon dioxide, water, heat, and light as byproducts.
Ethanol has a variety of applications
A variety of medical applications for alcohol include use as an antiseptic, disinfectant, and antidote in a variety of medical settings. Alcohol is applied to the skin in order to disinfect the skin before a needle stick or before surgery, among other things. Alcohol can be used to disinfect the skin of the patient as well as the hands of healthcare providers who are administering the treatment. It can also be used to clean other areas of the body as well as in mouthwashes and toothpaste. Whenever fomepizole is not available, ethanol is used to treat methanol or ethylene glycol toxicity, respectively.
This substance is useful in the medical field, where it is found in medical wipes and most commonly in antibacterial hand sanitizer gels, where it acts as an antiseptic due to its bactericidal and anti-fungal properties. Using ethanol as an antimicrobial, microorganisms are killed by dissolving the lipid bilayer of their membranes and denaturing their proteins. It also has antibacterial and antifungal properties, as well as being effective against viruses. Ethanol is used as an antidote for ethylene glycol poisoning and methanol poisoning, and it has been shown to be effective.
