preparation Embodiment 1
[0040] Preparation Example 1: Preparation of bis(2-ethylhexyl) isophthalate (DEHIP)
[0041] 498.0 g of purified isophthalic acid (IPA), 1170 g of 2-ethylhexanol (2-EH) (molar ratio of IPA:2-EH=1.0:3.0) and 1.54 g (relative to 100 parts by weight of IPA 0.31 parts by weight) titanium-based catalyst (tetraisopropyl titanate (TIPT)) was added to a 3L four-neck reactor equipped with a cooler, condenser, decanter, reflux pump, temperature controller, stirrer, etc. , and slowly raise the temperature of the reactor to about 170 °C. Produced water starts to be produced at about 170°C, and the esterification reaction is carried out at a reaction temperature of about 220°C under atmospheric pressure for about 4.5 hours while continuously introducing nitrogen, and the reaction is terminated when the acid value reaches 0.01.
[0042] After the reaction is completed, vacuum distillation extraction is performed for 0.5 to 4 hours to remove unreacted raw materials. In order to remove unre...
preparation Embodiment 2
[0043] Preparation Example 2: Preparation of Epoxidized Fatty Acid Butyl Ester (eFABE)
[0044] Using 500 g of epoxidized soybean oil and 490 g of butanol as reaction raw materials, transesterification was carried out to finally obtain 510 g of epoxidized butyl soybean oil (yield: 95%).
preparation Embodiment 3
[0045] Preparation Example 3: Preparation of epoxidized fatty acid 2-ethylhexyl ester (eFAEHE)
[0046] 584 g of epoxidized 2-ethylhexyl soybean oleate (yield: 95%) was obtained in the same manner as in Preparation Example 2 except that 490 g of 2-ethylhexanol was used instead of 490 g of butanol.
