What is Methyl decanoate?
Chemical properties
Methyl decanoate, a large methyl ester, is a clear colorless liquid. It can be used as a surrogate for the large methyl esters present in rapeseed and soybean derived biodiesel.
The Uses of Methyl decanoate
Intermediate for detergents, emulsifiers, wetting agents, stabilizers, resins, lubricants, plasticizers.
The Uses of Methyl decanoate
It is employed as an intermediate for caproic acid, detergents, emulsifiers, wetting agents, stabilizers, resins, lubricants, plasticizers and flavoring. As a chemical intermediate for alkanolamides, fatty alcohols & acids.
Definition
ChEBI: Methyl decanoate is a fatty acid methyl ester and a decanoate ester. It is a metabolite found in or produced by Saccharomyces cerevisiae.
Preparation
Methyl decanoate is prepared by esterification of capric acid with methanol or alcoholysis of coconut oil, purified by fractional vacuum distillation.
