fettsyraalkylester
Fettsyraalkylester, or fatty acid alkyl ester, is a class of esters formed from long-chain fatty acids and alcohols. The typical members are fatty acid methyl esters (FAME) and fatty acid ethyl esters (FAEE), where the fatty acyl group comes from a fatty acid and the alkyl group comes from methanol or ethanol. The general structure is R-CO-OR', with R representing the fatty acid chain and R' the alkyl group derived from the alcohol.
Production of fatty acid alkyl esters is usually achieved by transesterification of fats and oils (triglycerides)
The primary use of fatty acid alkyl esters is as biodiesel components. FAME dominates due to methanol’s
Safety and environmental considerations include biodegradability and renewable sourcing, which can reduce lifecycle greenhouse gas emissions
