Ethyl formate is an ester formed when ethanol (an alcohol) reacts with formic acid (a carboxylic acid). Ethyl formate has the characteristic smell of rum and is partially responsible for the flavor of raspberries, [3] occurring naturally in some plant oils, fruits, and juices. Ethyl formate does not occur naturally in the animal kingdom.
Formate is a common C-1 source in living systems. It is formed from many precursors including choline, serine, and sarcosine. It provides a C-1 source in the biosynthesis of some nucleic acids. Formate (or formic acid) is invoked as a leaving group in the demethylation of some sterols. [2]
Formic acid (from Latin formica ' ant '), systematically named methanoic acid, is the simplest carboxylic acid, and has the chemical formula HCOOH and structure H−C (=O)−O−H. It is an important intermediate in chemical synthesis and occurs naturally, most notably in some ants. Esters, salts and the anion derived from formic acid are ...
Infobox references. Methyl formate, also called methyl methanoate, is the methyl ester of formic acid. The simplest example of a carboxylate ester, it is a colorless liquid with an ethereal odour, high vapor pressure, and low surface tension. It is a precursor to many other compounds of commercial interest. [4]
An ester, ethyl formate, was also discovered, which is a major precursor to amino acids. This ester is also responsible for the flavour of raspberries, [8] leading some articles on Sagittarius B2 to postulate the cloud as smelling of ‘raspberry rum’.
Methyl acetate is occasionally used as a solvent, being weakly polar and lipophilic, but its close relative ethyl acetate is a more common solvent being less toxic and less soluble in water. Methyl acetate has a solubility of 25% in water at room temperature. At elevated temperature its solubility in water is much higher.
Solid sodium formate is used as a non-corrosive agent at airports for de-icing of runways in mix with corrosion inhibitors and other additives, which rapidly penetrate solid snow and ice layers, detach them from the asphalt or concrete and melt the ice rapidly. Sodium formate was also used as a road deicer in the city of Ottawa from 1987 to 1988.
Acetaldehyde (IUPAC systematic name ethanal) is an organic chemical compound with the formula CH 3 CHO, sometimes abbreviated as Me CHO. It is a colorless liquid or gas, boiling near room temperature. It is one of the most important aldehydes, occurring widely in nature and being produced on a large scale in industry.
