The document discusses three topics:
1) The neutralization process for removing fatty acids from oil by heating it and agitating it with caustic soda, which settles the fatty acids.
2) That technical grade glycerin produced by biodiesel plants is refined and pure, containing no contaminants.
3) That catalytic hydrogenation is more attractive than traditional stoichiometric methods for reducing carboxylic acid esters to alcohols, due to lower costs and higher efficiency.

Neutralization of oil by removing fatty acids with the help of this process, the oil is neutralized also
known deacidification in the neutralizer to remove the fatty acids by agitation with caustic soda. Oil is
heated up to about 60C by thermic fluid coils and oil is stirred by the stirrer. The fatty acids are settled at
the bottom as alkali soaps which is called soap stock from where it is taken out into soap pan.
Technical grade glycerin is a refined, highpurity sweet-tasting and of low toxicity organic compound
product that is water white with the greater part of its contaminants totally removed. Technical grade
glycerin contains no methanol, cleansers, salts, and other foreign matter. Biodiesel plants acquired from
SRS Engineering, unlike many of our rival's plants,
deliver technical grade glycerin ideal from the
beginning.
The reduction of carboxylic acid esters into the
corresponding alcohols is an important reaction in
organic synthesis and has extensive practical
applications. Compared with traditional stoichiometric
procedures using inorganic hydrides, homogeneous
catalytic hydrogenation systems are more attractive
because of their low cost, high efficiency, and atom
economy. This Acid esterification reaction of mainly salicylic acid is treated with an alcohol and ethanol is
performed in nearness of disintegrated 12-tungstophosphoric Br淡nsted Lowry acid impetus, a Keggin-
type polyoxometalate (POM). The observing of the reaction with the scent and the recuperation of the
impetus with locate is presented. A further change of current impetuses and the outline of new, savvy
metal buildings for synergist hydrogenation of esters depend on a profound comprehension of related
reaction components. However, mechanistic insights into catalytic ester hydrogenation reactions are still
lacking.
