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...

[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%).

[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.

Abstract

The present invention provides a plasticizer composition, a method for preparing the plasticizer composition, and a resin composition comprising the plasticizer composition, the plasticizer composition comprising: isophthalate-based material; and an epoxy-based alkyl ester compound represented by the following 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 is a single compound or a mixture of two or more compounds. (In chemical formula 1, R 1 is an alkyl group having 8 to 20 carbon atoms or an alkyl group containing at least one epoxy group, and R 2 is an alkyl group having 4 or 8 carbon atoms. ) The present invention can provide a plasticizer capable of improving plasticization when used as a resin composition by improving poor physical properties caused by structural constraints and a resin composition comprising the plasticizer. Physical properties such as tensile strength, migration resistance, and heat loss are required in the formulation. [chemical formula 1]

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. [0003] technical field [0004] The invention relates to a plasticizer composition, a resin composition and a method for preparing the plasticizer composition. Background technique [0005] 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. [...
