Abstract
The present invention relates to a method of preparing an ester-based composition, which includes mixing a dibenzoic acid and a carboxylic acid to prepare an acid mixture and reacting the acid mixture with an alcohol, wherein a product of the reaction includes a benzoic acid ester-based material and a carboxylic acid ester-based material. The preparation method can improve a reaction rate and a temperature rising rate, and can also reduce energy, by adding a carboxylic acid and/or a carboxylic acid ester-based material in a preparation process.
