    Abstract: A method of preparing a raw material mixture by mixing a dicarboxylic acid and a C4-10 mono-alcohol, and obtaining a product mixture including a diester-based material and water by reacting the raw material mixture in the presence of a catalyst. In the first step, at least one among a reactor temperature (Condition A), an alcohol input amount (Condition B), and an inert gas input amount (Condition C) is controlled, and the distinction between a beginning stage of a reaction and an ending stage of the reaction in Conditions A to C above is based on a reaction control point. The reaction control point is a point of time selected at which a conversion rate of the reaction is between 10% and 80%. This method produces a diester-based material with improved reactivity and improved energy expenditure.
