“The biodiesel reaction typically is a transesterification of soybean oil, canola oil
or palm oil (triglycerides) and methanol, producing fatty acid methyl esters or
biodiesel and a glycerol byproduct.”

The chemical formula is CH

-COOR", where R, R', and R"
are long
alkyl
chains. The three fatty acids RCOOH, R'COOH and R"COOH can
be all different, all the same, or only two the same.

Glycerol, also well known as glycerin and glycerine, and less commonly as
propane-1,2,3-triol, 1,2,3-propanetriol, 1,2,3-trihydroxypropane, glyceritol,
and glycyl alcohol is a colorless, odorless,
hygroscopic
, and sweet-tasting
viscous
liquid. Glycerol is a
sugar alcohol
and has three
hydrophilic
alcoholic
hydroxyl groups
(OH
