preparation Embodiment 1

[0037] Preparation Example 1: Preparation of DPHP

[0038] To a 3 L four-neck reactor equipped with cooler, condenser, decanter, reflux pump, temperature controller, stirrer, etc. were added 498.0 g of purified phthalic acid (PA), 1,170 g of 2-propane Heptyl alcohol (2-PH) (the molar ratio of PA and 2-PH is 1.0:3.0) and 1.54g (based on 100 parts by weight of PA is 0.31 parts by weight) titanium series catalyst (tetratitanate) as catalyst isopropyl ester (TIPT)) and slowly heated to about 170°C. Produced water started to be generated around about 170°C, and the esterification reaction was performed for about 4.5 hours while continuously adding nitrogen gas at a reaction temperature of about 220°C under atmospheric pressure conditions. The reaction was terminated when its acid value reached 0.01.

[0039] After the reaction is finished, distillation extraction is carried out under reduced pressure for 0.5 hours to 4 hours to remove unreacted raw materials. In order to remove ...

preparation Embodiment 2

[0040] Preparation Example 2: Preparation of TBC

[0041] Using 384 g of citric acid and 580 g of butanol as reaction raw materials, 706 g of tributyl citrate was finally obtained (yield: 98%).

preparation Embodiment 3

[0042] Preparation Example 3: Preparation of TOC

[0043] Using 384 g of citric acid and 1,014 g of 2-ethylhexyl alcohol as reaction raw materials, 1,029 g of tris-2-ethylhexyl citrate was finally obtained (yield: 98%).

Abstract

The present invention relates to a plasticizer composition, a resin composition, and preparation methods therefor. The present invention can provide: a plasticizer capable of improving physical properties, such as plasticizing efficiency, migration, tensile strength, elongation, stress migration, and light resistance, which are required for sheet prescription when used as a plasticizer of a resincomposition, by improving poor physical properties caused by structural limitations; and a resin composition containing the same.

Description

technical field [0001] Cross References to Related Applications [0002] This application claims priority and benefit from Korean Patent Application No. 10-2015-00167862 filed on Nov. 27, 2015, the disclosure of which is incorporated herein by reference in its entirety. technical field [0003] The invention relates to a plasticizer composition, a resin composition and a preparation method thereof. Background technique [0004] Typically, plasticizers form esters corresponding to the plasticizers by reaction between alcohols and polycarboxylic acids, such as phthalic acid or adipic acid. In addition, considering domestic and foreign regulations on phthalate plasticizers that are harmful to the human body, compositions of plasticizers that can replace phthalate plasticizers such as terephthalate , adipates and other polymer plasticizers have been continuously studied. [0005] Meanwhile, among phthalate products, dipropylheptyl phthalate (DPHP) is a product that is no...
