Abstract
A method of manufacturing a composition of alcohol esters of linear monocarboxylic acids with 6 to 26 carbon atoms from a vegetable or animal oil, neutral or acid, virgin or recycled, with monoalcohols having 1 to 18 carbon atoms, in the presence of a phosphate type catalyst or of an organophosphorous compound of a metal selected from the group made up of zirconium, hafnium and titanium, allows to directly produce, in one or more stages, an ester that can be used as fuel and a pure glycerin.
Claims18
A method of manufacturing a composition of alcohol esters of linear monocarboxylic acids with 6 to 26 carbon atoms and glycerin, comprising reacting a fatty substance of vegetable or animal origin with an aliphatic monoalcohol having 1 to 18 carbon atoms, in the presence of at least one basic heterogeneous catalyst comprising a phosphate, phosphonate, diphosphonate or organophosphorous compound of at least one group 4 metal selected from zirconium, hafnium and titanium.
