<p>Catalytic process for producing a composition of 6-26C linear monocarboxylic acid alcohol esters and glycerin, comprises reacting neutral or acidic, virgin or recycled vegetable oil or animal oil with 1-18C aliphatic monohydric alcohol, in the presence of a heterogeneous catalyst made of a zeolite (I), expressed on an anhydrous base in terms of oxide moles. Catalytic process for producing a composition of 6-26C linear monocarboxylic acid alcohol esters and glycerin, comprises reacting neutral or acidic, virgin or recycled vegetable oil or animal oil with 1-18C aliphatic monohydric alcohol, in the presence of a heterogeneous catalyst made of a zeolite of formula (XO 2:aY 2O 3:bM 2/nO) (I), expressed on an anhydrous base in terms of oxide moles. X : combination of at least two tetravalent elements comprising silicon, germanium, titanium, tin, zirconium and hafnium; Y1 : at least one trivalent element comprising aluminum, boron, iron, indium or gallium; a : number of moles of Y1 2O 3i.e. 0-0.5; M : at least one alkaline metal and/or alkaline earth metal comprising lithium, sodium, potassium, calcium or magnesium; n : 1 or 2; and b : the number of moles of M 2/nO i.e. 0 or 1.</p> |
