preparation Embodiment 1

[0142] Preparation Example 1: Diisononylcyclohexane-1,2-diester

[0143] Into a 3 L four-neck reaction vessel equipped with a cooler, condenser, decanter, reflux pump, temperature controller, stirrer, etc., were added 516.5 g of cyclohexane-1,2-dicarboxylic acid, 1,296 g of iso nonanol and 1.55 g of tetraisopropyl titanate as a catalyst, and the temperature of the reaction vessel was set at 230°C. Then, direct esterification was performed for about 6 hours while continuously introducing nitrogen gas, and was terminated when the acid value reached 0.1.

[0144] After the reaction, vacuum distillation and extraction were performed to remove unreacted raw materials. Thereafter, neutralization, dehydration, and filtration processes were performed to prepare 1,240 g of diisononyl cyclohexane-1,2-dicarboxylate (DINCH) (yield: 97%).

preparation Embodiment 2

[0145] Preparation Example 2: Bis(2-propylheptyl)cyclohexane-1,2-diester

[0146] 1,320 g (yield: 97 %) of bis(2-propylheptyl)cyclohexane-1,2-dicarboxylate (DPHpCH).

preparation Embodiment 3

[0147] Preparation Example 3: Tri(n-butyl) citrate

[0148] Except adding 384.2 g of citric anhydride and 670 g of n-butanol in the reaction vessel, 700 g (yield: 97%) of tri(n-butyl) citrate ( TnBC).

Description

technical field [0001] [Cross Reference to Related Application] [0002] This application claims the priority and rights of Korean Patent Application No. 10-2018-0067654 filed on June 12, 2018 and Korean Patent Application No. 10-2019-0063107 filed on May 29, 2019, both of which The disclosure content of this patent application is fully incorporated in this specification by reference. [technical field] [0003] The present invention relates to a plasticizer composition and a resin composition comprising the plasticizer composition, more particularly, to an environmentally friendly plasticizer composition having high stability and excellent basic properties and A resin composition comprising the plasticizer composition. Background technique [0004] Typically, plasticizers form esters through the reaction between alcohols and polycarboxylic acids such as phthalic acid or adipic acid. In addition, in consideration of domestic and foreign regulations on phthalate plasticiz...
