    摘要: The present invention includes (S1) preparing a raw material mixture by mixing a dicarboxylic acid and a C4-10 mono-alcohol, and (S2) obtaining a product mixture including a diester-based material and product water by reacting the raw material mixture in the presence of a catalyst, wherein in Step ( S2 ) , at least among a reactor temperature condition (Condition A), an alcohol input amount condition (Condition B), and an inert gas input amount condition (Condition C) is applied as a specific condition, 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, which is a point of time selected from points of time at which a conversion rate of the reaction is between 10% and 80%. According to the present invention, a method for producing a diester-based material with improved reactivity and improved energy expenditure is provided by controlling reaction conditions based on a specific conversion rate.

    摘要: The present invention relates to a plasticizer composition, a resin composition including the same, and a method of preparing the same. The plasticizer composition includes a cyclohexane 1,4-diester-based material; and an epoxidized alkyl ester-based material, wherein a weight ratio of the cyclohexane 1,4-diester-based material and the epoxidized alkyl ester-based material is 99:1 to 1:99, and the epoxidized alkyl ester-based material has an oxirane index (O.I.) of 1.5 or more. When the plasticizer composition is used as a plasticizer for a resin composition, properties such as plasticization efficiency, migration ability, tensile strength, elongation rate, migration upon stress, absorption rate, and the like may be improved.
