Abstract
A method is disclosed for the preparation of glycerol esters (triglycerides) of medium-chain length monocarboxylic fatty acids which consists of the reaction of the precursor free fatty acid and glycerol in the presence of a catalyst under partial vacuum. The process preferably uses a metal catalyst such as an oxide or a chloride of tungsten, molybdenum, calcium, zinc, chromium or magnesium. The method of the invention allows the preparation in high yield and high purity (>99.5%) of the final triglyceride. The present method allows the formation of triglycerides without solvent. Are also contemplated, the triglyceride obtained by the method, and the pharmaceutical composition containing the triglyceride as an excipient or as an active ingredient.
