A new process for enriching triterpene esters comprising: providing a mixture comprising a non-distilled vegetable oil and/or a non-distilled vegetable fat, further comprising triterpene esters, performing a mild transesterification with a lower alcohol, removing lower alcohol esters by deodorization, physical refining, evaporation or distillation, and recovering the remaining fraction rich in triterpene esters. Triterpene esters enriched with the method as well as uses of the same are also provided. One advantage is that it is a more economically viable way of achieving higher concentration of triterpene esters. There is both the chance to fully keep the natural distribution of triterpene esters but in the other end also to replace the natural level of cinnamic and acetic acids-triterpene esters with a high level of long fatty acid triterpene-esters.

The invention provides a method for the preparation of an amorphous silicate of at least one metal from the Group 4 of the Periodic Table of Elements with a total pore volume of at least 0.3 mL/g. The method of preparation involves the use of pore shaping conditions, which can be the use of a pore shaper and optionally an increased precipitation temperature, e.g. at least 60° C. The silicate of the invention is especially suitable in catalytic reactions such as esterifications, Michael additions, transesterifications, (ep)oxidations, hydroxylations, or in adsorbance of small inorganic and organic molecules e.g. CO.sub.2 or aromatic compounds.

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.
