Optimization for esterification of saturated palm fatty acid distillate by D-optimal design response surface methodology for biolubricant production
Optimization for esterification of saturated palm fatty acid distillate by D-optimal design response surface methodology for biolubricant production
The results have shown the ester products yields have been significantly increased up to 93% with selectivity of 99% SFA-TMP tri-ester after the optimization process by using D-optimal design. The results for lubrication properties have shown that the SFA PFAD-based esters have low-temperature properties with pour points value in the range of 18–35 °C, flash point (270–310 °C), onset oxidative stability temperature (251–322 °C) and viscosity indices (115–131), respectively. The results showed th
