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.

Synthesis and reactions

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]

Alternative names

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]

Uses

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]
