Butyl oleate is a fatty acid ester and an organic chemical found in liquid form. It has the formula C22H42O2 and the CAS Registry Number 142-77-8. [2] It is REACH registered and produced or imported into the European Union with the EC number of 205-559-6.
It is formed by the condensation of oleic acid and butanol often using an enzyme as catalyst or other biobased catalysts. [3] [4] [5] Ionic liquids may also be used as the catalyst. [6] It undergoes the Bouveault–Blanc reduction with oleyl alcohol and butanol as the products. [7]
It is also known as Butyl cis-9-octadecenoate, Oleic acid butyl ester, butyl 9-octadecenoate and 1-butyl oleate. The IUPAC name is butyl (Z)-octadec-9-enoate. [8]
It has approval for use as a food additive in Europe [9] and also the US by the FDA. [10] Various other uses include as a lubricant and lubricant additive, [11] paints and coatings additive, and as a plasticizer especially for PVC. [12] [13] Similar to other fatty acid esters, it has found use in biodiesel and as a fuel additive. [14]
