<p>Manufacturing a composition of 6-26C linear monocarboxylic acid alcohol esters and glycerin, comprises reacting fatty substances of animal or vegetable origin with 1-18C aliphatic monoalcohol in the presence of at least one acid-base heterogeneous catalyst based on metallophosphate (I). Manufacturing a composition of 6-26C linear monocarboxylic acid alcohol esters and glycerin, comprises reacting fatty substances of animal or vegetable origin with 1-18C aliphatic monoalcohol in the presence of at least one acid-base heterogeneous catalyst based on metallophosphate having a structure of formula (MP (1-y)O [3+5(1-y)]/2.nH 2O) (I). M : a metal cation of at least one member comprising aluminum, gallium or indium, preferably aluminum or gallium; y : 0-1, where y satisfies an equation of 3+5(1-y)>= 0; and n : number of associated water molecules, and optionally be zero.</p> |
