TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Process: The esterification process in step (a) is carried out using at least 18C:1, 18C:2 fatty acids or their mixture at 110 degrees C and 160 degrees C with an acid catalyst. The acid catalyst is selected from concentrated sulphuric acid, concentrated hydrochloric acid and/or sulphonic acid at a concentration of 0.5-1% of the total mixture. The fractional distillation process in step (b) is carried out at a pressure of 5-30Pa. The crystallization process in step (c) and (d) where it is dry or solvent fractionation. The alcohol selected from methanol, ethanol and/or isopronol is used in solvent fractionation process. The transesteritication process (e) is carried out using palm oil, palm kernel and palm oil products with methanol or ethanol at 60-65 degrees C for 45 minutes to 1 hour and using 0.25-1% alkaline catalyst selected from sodium hydroxide or sodium methylate. Preferred Components: The 18C, 18C:l and 18C:2 methyl and/or ethyl esters are mixed in a proportion to yield a pour point between -12 to -21 degrees C. The proportion consist less than 10% saturated methyl esters and/or ethyl esters and at least 90% of 18C:1 and/or 18C:2 or their methyl or ethyl esters. The methyl esters consists (wt.%) of methyl myristate, methyl palmitate, methyl oleate or methyl linoleate. Methyl ester composition comprises (wt.%) of methyl myristate (0.5), methyl palmitate (5), methyl oleate (83.6) and methyl linoleate (11) to yield a pour point of -21 degrees C or comprises of methyl myristate (0.6), methyl palmitate (5.7), methyl stearate (2), methyl oleate (79) and methyl linoleate (12.7) to yield a pour point of -15 degrees C or methyl myristate (0.6), methyl palmitate (6.3), methyl stearate (2.9), methyl oleate (74.6) and methyl linoleate (15.7) to yield a pour point of -12 degrees C or methyl myristate (0.7), methyl palmitate (6.7), methyl stearate (0.4), methyl oleate (75.5) and methyl linoleate (16.7) to yield a pour point of -9 degrees C or comprises methyl myristate (1.64), methyl palmitate (5.04), methyl stearate (0.65), methyl oleate (72.85), methyl linoleate (19.38) and methyl arachidate (0.45) to yield a pour point of -33 degrees C. The total saturated methyl or ethyl esters consists of myristic acid, palmitic acid and stearic acid. EXAMPLE - One mole of technical grade of oleic acid (with fatty acid composition (wt.%) of stearic acid (0.5), palmitic acid (5.5), oleaic acid (80.2) and of linoleic acid (13.8)) was esterified with six moles of methanol at 160 degrees C. A concentrated sulphuric acid (0.5 wt.%) was used as catalyst. After 4.5 hours of reaction, the crude product was water washed until the decanted aqueous layer was neutral. The dried product was subjected to second stage of esterification (re-esterification). The esterification steps were similar to the first stage esterification, except catalyst (0.3 wt.%) was used. The resultant methyl esters from the first and second stage esterification exhibited pour point of -15 to -21 degrees C respectively.
