This invention discloses a reaction system for producing fatty-acid alkyl esters using liquid film reactors, with countercurrent flow scheme based on the alcoholysis of fats and oils. Reaction system comprises a descending film reactor using semi-structured packing for generating interfacial area. It is fed through the bottom with oil or fat, and with a mixture containing alcohol, glycerol and catalyst through an intermediate stage. Products are a mixture of fatty-acid alkyl esters, alcohol and catalyst and alcohol, glycerol and catalyst, exit via the top and the bottom of the reactor, respectively. Volumetric packing fraction is between 2% and 50%, reaction temperature from 25 to 180° C., molar ratio alcohol to oil between 3:1 and 10:1, and CH3OH, NaOH, KOH, or their mixtures (0.5% to 3% based on the oil mass flow rate). Conversion and yield in a single reaction step are greater than 99.7% and 99.9%, respectively.

An ester of a phospholipid with conjugated linoleic acid for use in the therapeutic treatment of or as a food supplement for psychiatric disorders with neuroinflammatory and neurodegenerative basis, such as depression and schizophrenia.

The present invention relates to a method of producing fatty acid alkyl ester from an organic oil source containing at least one free fatty acid, wherein the oil source has an acid number of at least 30 mg KOH/g oil source and wherein the method comprises the steps of a) reacting the oil source with glycerol at a temperature, which does not exceed 180° C. during the reaction, in the presence of a catalyst comprising at least one alkyl or aryl sulfonic acid or an homoanhydride thereof; and b) transesterification of the reaction product from step a) with an alkanol; and c) isolating the fatty acid alkyl ester from the reaction product of step b).

The present disclosure relates to a synthetic vegetable oil and an environmental-friendly flame-retardant hydraulic oil composition including the same, and a preparation method thereof, and provides a method of preparing a glycerin-ester-based lubricating base oil through a catalyst-free and rinsing-free process, a glycerin-ester-based lubricating base oil that is a synthetic vegetable oil obtained by the method, and an environmental-friendly flame-retardant hydraulic oil composition that contains the glycerin-ester-based lubricating base oil and that is capable of reducing electricity consumption by 7 to 8% compared to mineral oil-based lubricating oils due to excellent flame retardancy (with self-extinguishing function) and lubricity.

Disclosed is a vegetable fat composition comprising at least two different triglycerides comprising fatty acids selected from saturated fatty acids and unsaturated fatty acids, wherein at least one of the triglycerides comprises C14-fatty acids. Additionally disclosed is a method of producing such a vegetable fat composition in addition to various uses of such a composition. A vegetable fat composition as disclosed has some of the properties from cocoa butter substitute and some of the properties from cocoa butter replacer, combined in one product, in addition to being a cost effective vegetable fat composition.

A hydrotreating and isomerization pre-treatment process in a biofuel production plant, which is characterized in that it occurs from a raw supply consisting of an organic feed comprising secondary materials such as frying oils, category 1 animal fats, residual oils or by-products consisting of monoglycerides, diglycerides, triglycerides and free fatty acids, which is added to a recycling stream consisting of a mixture of mono-, di- and triglycerides free of impurities and exiting an esterification unit, said process occurring by means of hydrolysis with excess water, under controlled pressure and temperature conditions, thus obtaining the partial or total conversion of the supply into glycerol and fatty acids, the excess water introduced into the hydrolysis process acting as a solvent for impurities of various nature present in ionic form, thus removing most of the heavy metals, as well as of the chlorides present in said supply.
