Isopropyl formate is an organic chemical compound. Like many other aliphatic carboxylic acid esters, it has an odor. It is described as pleasant and fruit-like, similar to plums or pears.[1] In fact, many fruits contain isopropyl formate, but their smell is determined by a combination of esters, not by isopropyl formate alone.[2]
Production
Isopropyl formate can be produced by a typical Fischer Esterification, of isopropyl alcohol and formic acid, catalyzed by sulfuric acid[3]:
- HCOOH + (CH3)2CHOH → C4H8O2 + H2O
Use
Isopropyl formate can be used as a flavour.[1]
Fate
When released in the atmosphere, isopropyl formate is mostly degraded by reaction with hydroxyl radicals and secondarily by chlorine atoms.[4]
