Embodiment Construction

[0016] Next, the present invention will be described in detail.

[0017] According to the invention, a fat or oil is reacted with an alcohol using an insoluble solid catalyst. In the case of the manufacture of fatty acid alkyl esters, in addition to the above mentioned effects, the content of fatty acid alkyl esters in the ester phase is improved due to improved conversion and improved recovery of fatty acid alkyl esters from the glycerin phase , so that the purification cost can be reduced. Furthermore, unlike the conventional production method using a homogeneous catalyst, the step of removing the catalyst by washing with water is unnecessary; in this regard, the method of the present invention is an advantageous method. Also in the case of glycerol production, recovery of glycerin from the ester phase is improved and since dilution with water is unnecessary, glycerin of high concentration and high purity can be obtained in the glycerin phase, thereby reducing purification ...

Abstract

The method of producing fatty acid alkyl esters and / or glycerine of the present invention is a method of producing high-purity fatty acid alkyl esters and / or glycerine advantageously from the energy viewpoint while reducing the energy consumption of the production, and the products can be used in various fields of application, for example in biodiesel fuels, foods, cosmetics and pharmaceuticals. The above-mentioned method of producing fatty acid alkyl esters and / or glycerine by reacting a fat or oil with an alcohol using an insoluble solid catalyst in a reaction apparatus comprising at least one reactor, comprises (a) a step of obtaining low-boiling components removed liquid by removing low-boiling components or fraction from an effluent liquid of a reactor and (b) a step of separating the fatty acid alkyl esters and glycerine from the low-boiling components removed liquid, wherein an eluted active metal component of the insoluble solid catalyst in the effluent liquid of a reactor amounts to a level not higher than 1,000 ppm.

Description

technical field [0001] The present invention relates to a method for the production of fatty acid alkyl esters and / or glycerin and to compositions comprising fatty acid alkyl esters. More specifically, the present invention relates to methods for the manufacture of fatty acid alkyl esters and / or glycerol useful in fields such as fuel, food, cosmetics, and pharmaceuticals, and to compounds suitable for use in biodiesel fuel or as surfactant intermediates. Compositions comprising fatty acid alkyl esters. Background technique [0002] Those fatty acid esters derived from vegetable fats and oils can be used as edible oils, and in addition, they can also be used in fields such as cosmetics and pharmaceuticals. In recent years, it has attracted attention as an additive to fuels such as light oil. For example, they are added to light oil at a few percent as plant-derived biodiesel fuel to reduce CO 2 emissions. Glycerin is mainly used in various fields such as a raw material fo...
