preparation Embodiment 1
[0119] Into a 3-liter four-neck reactor equipped with a cooler, condenser, decanter, reflux pump, temperature controller and stirrer 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 reaction temperature was set at 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 performing distillation extraction, 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] Except that 384 g of trimellitic anhydride and 1,170 g of 2-ethylhexanol were added to the reactor, the same method as in Preparation Example 1 was carried out to prepare 1,060 g of trimellitic acid tris(2-ethylhexanol) Hexyl) ester (TEHTM) (Yield: 97%).
preparation Embodiment 3
[0125] Except that 384g of trimellitic anhydride and 1,296g of isononyl alcohol were added to the reactor, the same method as in Preparation Example 1 was carried out to prepare 1,140g of triisononyl trimellitate (TINTM) ( Yield: 97%).
[0126] Select the cyclohexane-1,2-diester substances prepared in Preparation Example 1, the trimellitic acid tris (2-ethylhexyl) ester prepared in Preparation Example 2, and the Triisononyl trimellitate, epoxidized oil, diisodecyl phthalate (DIDP) and phenyl alkylsulfonate (ASPE, CAS No. 91082-17-6) prepared in 3 One or more of the mixtures are used to prepare the plasticizer compositions of Examples and Comparative Examples, and the details 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.
