Abstract. Biodiesel plants are struggling to find value added applications for fatty acid methyl esters (FAME). One option for FAME valorization would be dibasic esters, which can be transesterified with 2-ethylhexyl (2EH) or other alcohols to produce lubricant basestocks and achieve the most widespread viscosity grades VG46 and VG32.

Acid oil obtained from Acidulation process having high FFA (50- 80 %) (Harwood et al., 2007). The cost of acid oil produced in the refining process is three times low as compared to the refined vegetable oil. Due to low-cost feedstock, this oil can be used for the production of fatty acid methyl ester (FAME).
Amplified distillation is a useful technique for the quantitative analysis of mixtures of fatty acid esters, especially for the detection and estimation of minor components and for the analysis of small samples. The amplified distillation of free fatty acids is largely limited to qualitative work on account of the formation of azeotropes with mineral oils.

Fatty acid methyl esters (FAME), valuable oleo-chemicals and main constituent of biodiesel, can be manufactured in a continuous process using reactive distillation. (Dimian, 3 2007) Reactive distillation (RD) is the process in which chemical reaction and separation are carried out simultaneously within a fractional distillation apparatus.
Fatty acids are the major component of lipids, and the physical, chemical, and physiological properties of a lipid class depend primarily on its fatty acid composition. The fatty acid composition is determined as the methyl esters of fatty acids by gas-liquid chromatography (GC) (1–3). Saponification followed by methylation is a classical ...
Fatty acids could be isolated by Colgate-Emery steam hydrolysis, hydrolysis of vegetable oils using inorganic base catalyst or lipase, and base-catalyzed hydrolysis of pure fatty acid methyl ester. There are three steps in the synthesis of pure fatty acid methyl ester which are neutralization, transesterification, and fractional distillation.
Fatty acids distillation. The distillers are towers with structured packing to fractionate heavy and light boiling impurities and to ensure that the fatty acids are distilled at the lowest possible temperature. Squeezing of the residue is carried out in a separate distiller.
For such experiments, any column and conditions may be used that provide separation of typical methyl esters of fatty acids in increasing order of the boiling points. As for the data acquisition system has a normal chromatographic software installed on a computer for measuring the RT and areas of eluting peaks (peak detection mode).
