Abstract: The invention provides a process for producing a monoglyceride-containing composition by reacting glycerin with at least one kind of acyl-containing compound selected from fatty acid and glycerin ester, the reaction being conducted with a catalyst containing at least one metal selected from iron, cobalt and manganese in an amount of 0.1 to 60 ppm in terms of metal (weight ratio to the total weight of glycerin and the acyl-containing compound), as well as a process for producing a monoglyceride-containing composition by reacting glycerin with at least one kind of acyl-containing compound selected from fatty acid and glycerin ester, including a step of maintaining the amount of water at 500 to 5000 ppm in the reaction system after the degree of conversion in the reaction of glycerin with fatty acid reaches 90% or more based on the fatty acid, or during the ester exchange reaction of glycerin with glycerin ester.

Abstract: Procedimiento para producir una composición que contiene un monoglicérido, que comprende la etapa de hacer reaccionar glicerina con al menos una clase de un compuesto que contiene acilo seleccionado entre el grupo constituido por un ácido graso y un éster de glicerina, caracterizado porque la cantidad de agua se mantiene en 500 a 5000 ppm en el sistema de reacción después de alcanzar un grado de conversión en la reacción de la glicerina con el ácido graso de 90% o más sobre la base del ácido graso, o durante la reacción de intercambio de éster de la glicerina con el éster de glicerina.

Abstract: A process for producing a monoglyceride-containing composition which comprises reacting glycerol with at least one acylated compound selected among fatty acids and glycerol esters, wherein the reaction is conducted in the presence of a catalyst comprising at least one metal selected among iron, cobalt, and manganese, the catalyst being used in an amount of 0.1 to 60 ppm (of the total weight of the glycerol and the acylated compound) in terms of metal amount. Also provided is the process for producing a monoglyceride-containing composition which includes a step in which the amount of water contained in the reaction system is kept at 500 to 5,000 ppm either after the conversion in the reaction of glycerol with a fatty acid has reached 90% or higher in terms of the conversion of the fatty acid or during the transesterification of glycerol with a glycerol ester.
