Disclosed is a method of producing an estolide having high structural stability, including: a) preparing a fatty acid mixture from biomass-derived oil; b) separating the fatty acid mixture into a C16 fatty acid and a C18 fatty acid; c) converting the C18 fatty acid into a C18 or C17 linear internal olefin; and d) subjecting the C18 or C17 linear internal olefin and the C16 fatty acid to an estolide reaction, thus obtaining an estolide.

Provided is a method for producing an ethyl acetate production catalyst that has high producibility and exceptional catalytic performance, the catalyst being such that a heteropolyacid and/or a salt thereof is carried near the surface of a carrier. A method for producing an ethyl acetate production catalyst, the method including, in the stated order: (1) an impregnation step in which a silica carrier is impregnated with an aqueous solution of a heteropolyacid or a salt thereof, constituting 80-105 vol % of the saturation absorption capacity of the carrier, to form an impregnated body; and (2) a drying step in which the impregnated body is dried at a fixed-rate drying speed of 5-300 g.sub.H2O/kg.sub.supcat.Math.min.
