GC-MS data corresponding to: Methanol-Based Esterification of Palm Oil Sludge – Preparation of Fatty Acids (Palmitic and Oleic) Ethyl Esters via Ethyl Acetate Transesterification by Javier Chaparro-Acosta(1) and Juan-Manuel Urbina-González(2*) 1Escuela de Ingeniería Química, Universidad Industrial de Santander, Bucaramanga, 680002, Colombia 2Escuela de Química, Universidad Industrial de Santander, Bucaramanga, 680002, Colombia * Correspondence: jurbina@uis.edu.co Abstract Acid catalyzed Fischer esterification of fatty acids using methanol (as reagent and solvent) allow the preparation of long chain alkyl methyl esters. Transesterification of palm oil in basic media using methanol is also a known path to monoalkyl methyl ethers derived of fatty acids. In this work we report the Fischer esterification using methanol of a sample of local palm oil sludge (a fraction rich in fatty acids) and how during the extraction with ethyl acetate a transesterification reaction occurred, allowing the preparation of ethyl esters of oleic and palmitic acids as main compounds.
