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.
