Transesterification and Reactive Extraction of Castor Oil for synthesis of Biodiesel/Biolubricant
IOP Conference Series: Earth and Environmental Science, 2021 Abstract The use of non-edible vegetable oils as a substitute for petroleum fuel has gained popularity due to increased environmental contamination and depletion of petrochemical resources. There is high percentage of oil in castor seeds, that can be converted into biodiesel and biolubricant. Castor oil has high lubricity due to presence

SYNTHESIS OF TRIMETHYLOLPROPANE ESTER BASED ON CHICKEN FAT AS BIOLUBRICANTS
Revista Mexicana de Ingeniería Química, 2018 In this project, chicken fat was transesterificated to methyl esters of chicken fat (MECF) with an efficiency of 80%, subsequently added trimethylolpropane (TMP) to get as majority product esters of trimethylolpropane (biolubricants). Temperature, molar ratio MECF:TMP and catalyst were evaluated using a mixed-level factorial design.
