It also provides an alternate process of direct esterification of fatty acid methyl esters and glycerol under catalytic condition for the production of MCT. Using a continuous or semi-continuous process or by batch processing, glycerol is reacted with C8-12 methyl ester fraction and refined glycerin at about 200°C-220°C with partial condenser to reflux the methyl esters during the course of reaction and total condenser to continually remove reaction by product such as methanol (Figure 2).</em></p><p><em> </em></p><p><em>The C8-12 methyl ester fraction is derived from the fractionation of whole cut coconut methyl ester and it is accomplished by means of a distillation unit commonly referred to as a "fractionation column" known to the person skilled in the art. The fractionation column maintained at temperature of tower top at 55-65 mbar pressure at 95°C-100°C and column bottom temperature of 170°C-180°C where the short chain lengths are collected referred as C8 to C12 (C8-C12) methyl ester cut. The bottom cut is a fraction of CI 2- 18 methyl esters in the crude form and can be further distilled or fractionated for other uses like oleochemicals and surfactants. The C8-12 methyl ester cut yields to about 16% to 18% of the total feed of coconut methyl ester and 84% to 88% of crude C12-18 methyl ester cut. The C8-12 fraction is composed of C8 (Caprylic) of 13-45%, CIO (Capric) of 8-35% and C12 (lauric) of 2-70%. The C8 to C12 alkyl group may contain C6 (Caproic) of 2% or less and C14 (myristic) of 8% or less. Preferably, the C8-12 fraction is composed of C6 1% or less, C8 of 35-45%, CIO of 25-31%, C12 of 20-30% and C14 of 0-4%. This composition is ideal for the preparation of the final MCT Oil. Alternatively, fractionation of different fatty acids or their ester can be accomplished by other means, such as using various solvents (Lindqvist et al. 1974)</em></p><p><em> </em></p><p><em>The C8-12 fraction can also be prepared in a similar fractionation column using coconut fatty acids as feedstock or palm kernel fatty acids or its methyl ester derivative. The resulting cut of the C8-12 fraction should be preferably made up also of C6 of 1% or less, C8 of 35-45%, CIO of 25-31%, C12 of 20-30% and C14 of 0- 4%.</em></p><p><em> </em></p><p><em>The MCT oil is then prepared by reacting the C8-C12 methyl ester fractions with glycerol and subsequently purifying such (Figure 2). The molar ratio of glycerol to the C8-12 methyl ester fraction is from 1 mole of glycerol to 3 to 4 moles of C8- C12 methyl esters, preferably at 1 mole of glycerol to:3.3 to 3.9 moles C8-12 methyl esters. According to the present invention, the reaction is performed in the presence of a catalyst. The reaction is undertaken at 140°C to 260°C, more preferably at 180°C to 220°C, and most preferably within 200°C to 220°C under vacuum at 60 to 80 mbar with regulated nitrogen blow until conversion to triglycerides reaches 95% or higher. Alternatively, such process can also be accomplished under atmospheric condition. The methanol as result of the condensation of glycerol and methyl esters is continually condensed and removed from the reaction mixture and the excess methyl ester is allowed to reflux in order to drive the reaction toward triglyceride formations. Skilled person in the art would know the correct balance of temperature, catalyst and applied vacuum to allow faster conversion and shorter reaction time of the esterification process. The excess C8-12 methyl ester is collected and can be re-used during the esterification stage.

The present invention of esterification of glycerol and C8-12 methyl ester fraction is integrated in a refinery plant in order to produce edible MCT Oil. The crude MCT resulting from the direct esterification of glycerol and C8-12 methyl esters can be characterized having unreacted C8-12 methyl esters from the excess molar ratio, traces of alcohol like methanol and higher levels of monoglycerides and diglycerides resulting from their incomplete condensation with C8-12 methyl esters.</em></p><p><em> </em></p><p><em>The refinery scale plant of the present invention can be characterized by having pressure leaf filters, bleaching tanks, steam deodorizers and collection tanks.

Majority of the unreacted methyl esters will be stripped off including residual methanol. The spent catalyst will be removed by passing the crude MCTs thru a pressure leaf filter heated at 50°C to 60°C and will be collected in the bleaching tank. In the bleaching tank, it will be heated to about 90°C to 110°C under vacuum of 60 to 80 mbar for about 30 to 60 minutes. The amount of bleaching earth and activated carbon is added, from 0.30 to 0.50% w/w of the total mixture. After the required residence time, vacuum is stopped. Spent bleaching agents are removed by passing through a pressure leaf filter at 50°C to 60°C. In the steam deodorization, the bleached MCTs will be heated at about 170°C to 200°C. Firstly, it will be heated at 170°C at 4 to 8 mbars for about 2 hours. Finally, it will be heated further to 200°C with applied vacuum of 4 to 8 mbars for another 4 hours.

For example, MCTs can be prepared with individual cuts of C8, CIO and C12 with trace amounts of C6 and C14. These individual cuts can be in the form of fatty acid methyl esters or fatty acids and blended to the desired ratios to arrive at the same MCT oil composition claimed by this current invention.
