The maximum yield of ester is obtained at the
temperatures of 45G5 8C. The decrease in yield is observed
when the reaction temperature goes above 50 8C. However,
other researchers [3,4] achieved better results at temperatures
above 50 8C and up to 70 8C while using refined
linseed oil and brassica carinata oil, respectively. The
reaction temperatures greater than 60 8C should be avoided,
in the case of rubber seed oil, because they tend to accelerate
