Formic anhydride can be isolated by low-temperature, low-pressure distillation, but decomposes on heating above room temperature. It decomposes into formic acid and carbon monoxide. The decomposition of formic anhydride may be catalyzed by formic acid. Formic anhydride can be detected in the gas-phase reaction of ozone with ethylene. The molecule is planar in the gas phase. Formic anhydride Formic anhydride, also called methanoic anhydride, is an organic compound with the chemical formula and a structural formula of (H(C=O)−)O. It can be viewed as the anhydride of formic acid (HCOOH). Formic anhydride can be obtained by reaction of formyl fluoride with sodium formate
Chlorogenic acid Even the 1976 IUPAC recommendations are not entirely satisfactory when applied to some of the less common chlorogenic acids. Chlorogenic acid Chlorogenic acid (CGA) is the ester of caffeic acid and (−)-quinic acid, functioning as an intermediate in lignin biosynthesis. The term "chlorogenic acids" refers to a related polyphenol family of esters, including hydroxycinnamic acids (caffeic acid, ferulic acid and "p"-coumaric acid) with quinic acid. Despite the "chloro" of the name, chlorogenic acids contain no chlorine. Instead, the name comes from the Greek χλωρός (light green) and -γένος (a suffix meaning "giving rise to"), pertaining to the green color produced
