N-methyl fatty hydroxamic acids (N-MFHAs) is a derivative of acid (FHA), were synthesized from ketapang seed oil (Terminalia catappa L.) with hydroxylamine enzymatically using immobilized lipase (Lipozyme TL IM). N-MFHAs that are still in mixed state triglycerides the oil. This research aims to determine optimum conditions for separation into their single components and percentage composition H...
