This study explores the production of biodiesel fuels using acorn kernel oil (AKO) as an alternative source of triacylglycerol (TAG). The AKO, derived from acorns of various oak tree species, was subjected to transesterification processes with methanol and ethanol in the presence of suitable catalysts (acid and base). The study also investigated the impact of a room temperature ionic liquid on the base-catalyzed transesterification process. Characterization of the resulting product mixtures was done using 1H-NMR spectroscopy, confirming the presence of transesterified products and providing percentage conversion data. The results showed high conversion rates, ranging from 96% to 98% for acorn kernel oil methyl esters (AKOME) and 96% to 97% for acorn kernel oil ethyl esters (AKOEE).
