preparation Embodiment 1

[0119] To a 3-liter four-neck reactor equipped with a cooler, condenser, decanter, reflux pump, temperature controller and stirrer was added 516.5 g of cyclohexane-1,2-dicarboxylic acid, 1,296 g of iso-iso Nonanol and 1.55 g of tetraisopropyl titanate as a catalyst, and the reaction temperature was set to 230°C. The direct esterification reaction was carried out for about 6 hours while continuously feeding nitrogen, and the reaction was terminated when the acid value reached 0.1.

[0120] After completion of the reaction, distillation extraction was performed under reduced pressure in order to remove unreacted raw materials. After distillation extraction was performed, a neutralization process, a dehydration process, and a filtration process were performed to prepare 1,240 g of diisononyl cyclohexane-1,2-dicarboxylate (yield: 97%).

[0121]

preparation Embodiment 2

[0123] The same method as in Preparation Example 1 was carried out except that 384 g of trimellitic anhydride and 1,170 g of 2-ethylhexanol were charged into the reactor to prepare 1,060 g of tris(2-ethyl trimellitic acid) ethylhexyl) ester (TEHTM) (yield: 97%).

preparation Embodiment 3

[0125] The same method as in Preparation Example 1 was carried out except that 384 g of trimellitic anhydride and 1,296 g of isononyl alcohol were added to the reactor to prepare 1,140 g of triisononyl trimellitic acid (TINTM) ( Yield: 97%).

[0126] The cyclohexane-1,2-diesters prepared in Preparation Example 1, the trimellitic acid tris(2-ethylhexyl) ester prepared in Preparation Example 2, and the In triisononyl trimellitic acid, epoxidized oil, diisodecyl phthalate (DIDP) and phenyl alkyl sulfonate (ASPE, CAS No. 91082-17-6) prepared in 3 The plasticizer compositions of the Examples and Comparative Examples were prepared by mixing one or more of these, the details of which are summarized in Table 1 below. The evaluation of the physical properties of the plasticizer composition was performed according to the following test items. For substances other than those prepared in Preparation Examples, commercially available products were used.

Description

technical field [0001] CROSS-REFERENCE TO RELATED APPLICATIONS [0002] This application claims the benefit of Korean Patent Application No. 10-2018-0067653 filed in the Korean Intellectual Property Office on June 12, 2018, the disclosure of which is incorporated herein by reference in its entirety. [0003] The present invention relates to a plasticizer composition and a resin composition comprising the same, and to an eco-friendly plasticizer composition excellent in safety and basic physical properties and a plasticizer composition comprising the same resin composition. Background technique [0004] In the polyvinyl chloride compounding industry, which requires high heat resistance and low volatilization loss as the main desired physical properties, it is necessary to use plasticizers appropriately according to the application. For example, in the case of polyvinyl chloride compounds used in wires and cables, according to tensile strength, elongation, plasticization eff...
