is non-edible and is commercially obtained after
extraction from rubber seeds. Methanol with a purity
of 99.5% and calcium oxide, CaO are purchased from
Chemind Chemicals Ltd. Fatty acid composition of
crude rubber seed oil has been obtained from GC-MS
data taken at CUSAT, Cochin. Physical and chemical
properties of crude rubber seed oil had been analysed.
Physical properties include density, viscosity, flash &
fire point, cloud & pour point and calorific value.
Chemical properties include acid value, iodine value
and saponification value.
