preparation Embodiment 1

[0039] Preparation Example 1: Preparation of bis(2-ethylhexyl) isophthalate (DEHIP)

[0040] 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 generated 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.

[0041] 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 unr...

[0042] Preparation Example 2: Preparation of Epoxidized Fatty Acid Butyl Ester (eFABE)

[0043] Using 500 g of epoxidized soybean oil and 490 g of butanol as reaction raw materials, a transesterification reaction was carried out to finally obtain 510 g of epoxidized butyl soybean oil (yield: 95%).

preparation Embodiment 3

[0044] Preparation Example 3: Preparation of epoxidized fatty acid 2-ethylhexyl ester (eFAEHE)

[0045] 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.

Abstract

Provided are a plasticizer composition, a method for preparing the same, and a resin composition including the plasticizer composition, the plasticizer composition comprising: an isophthalate-based material; and an epoxy-based alkyl ester compound represented by chemical formula 1, wherein the weight ratio of the isophthalate-based material to the epoxy-based alkyl ester compound is 99:1 to 1:99, and the epoxy-based alkyl ester compound comprises a single compound or a mixture including at least two kinds of compounds. (In chemical formula 1, R1 is an alkyl group having eight to 20 carbon atoms or an alkyl group containing at least one epoxy group, and R2 is an alkyl group having four or eight carbon atoms.) The present invention can provide: a plasticizer capable of improving physical properties required when used as a plasticizer for a resin composition, such as tensile strength, migration resistance, and heating loss, by ameliorating inferior physical properties caused by structural limitations; and a resin composition including the plasticizer.

Description

technical field [0001] Cross References to Related Applications [0002] This application claims the priority and benefit of Korean Patent Application No. 10-2015-0105324 filed on July 24, 2015 and Korean Patent Application No. 10-2016-0092874 filed on July 21, 2016, which The disclosure is incorporated herein by reference in its entirety. technical field [0003] The invention relates to a plasticizer composition, a resin composition and a method for preparing the plasticizer composition. Background technique [0004] Typically, plasticizers form esters through the reaction of alcohols and polycarboxylic acids such as phthalic acid or adipic acid. In addition, considering domestic and international regulations on phthalate-based plasticizers that are harmful to humans, plasticizer compositions that can replace phthalate-based plasticizers, such as based on Terephthalate-based plasticizers, adipate-based plasticizers and other polymer-based plasticizers. [0005] At...
