Formate

 

(or formiate), a salt or ester of formic acid. The most important ester formates are the methyl formic ester (methyl formate, HCOOCH5) and ethyl formic ester (ethyl formate, HCOOC2H3). Both are colorless liquids with a pleasant odor. The melting point of methyl formate is 31.5°C, and that of ethyl formate, 54.1°C. Both esters are commercially prepared from carbon monoxide and the corresponding alcohol. They are used as solvents and fumigants and in organic synthesis; for example, ethyl formate is used in the preparation of vitamin B1. Certain ester formates are used as aromatic substances in the manufacture of perfumes. The esters of orthoformic acid are sometimes classified as formates.

The most important salt formate is the sodium salt HCOONa, which is used in the preparation of oxalic acid.

Chemical fractionation was performed on a 250mm [x] 10mm semi-preparative column packed with Nucleosil 100-7C18 (Macherey-Nagel, Dueren, Germany) at a controlled temperature of 40[degrees]C, using a gradient system starting at time point zero with a mixture of ammonium formiate (0.01M, pH 7.0), methanol and acetonitrile (60:30:10, v/v/v).
The donor hydrogen molecules commonly used are, among others, hydrazine, alcohols, aromatic hydrocarbons, limonene, cyclohexene, formic acid, formiates, phophinates and phosphinic acid.
The use of alternative de-icing salts and agents, such as calcium chloride, acetates, formiates or molasses-based organic substances is recommended.
