Esterification process catalyzed by ionic liquids for fatty acid methyl esters production

Ver documento

Detalhes bibliográficos
Resumo:Biodiesel is a mixture of fatty acid methyl esters (FAMEs), prepared from vegetable oils and animal fats through esterification of free fatty acids (FFAs) and/or through transesterification of triglycerides, that arises as a possible diesel substitute. It can be produced using basic or acid catalysts. However, these traditional catalysts present problems, so there is a need for the searching of more sustainable alternative catalysts. The ionic liquids (ILs) are molten salts which exist in liquid state at temperature below 100°C and as catalysts are an interesting alternative to the traditional catalysts because ILs can be reusable and are environmentally friendly.
