Problems solved by technology

[0007] Meanwhile, diisononyl terephthalate has poor compatibility with PVC resin, so despite its excellent cost-competitiveness, it is limited in use, and although research has been conducted to remedy this weakness, so far not much progress yet

preparation Embodiment 1

[0042] Preparation Example 1: Preparation of Diisononyl Terephthalate

[0043] Into a 4-neck 3-liter reactor equipped with cooler, water stripping unit, condenser, decanter, reflux pump, temperature controller, stirrer, etc., 498.4 g of purified terephthalic acid (PIA), 1172.1 g Isononanol (KH Neochem) (the molar ratio of terephthalic acid:isononanol is 1:3) and 1.54 g of a titanium-based catalyst (TIPT, tetraisopropyl titanate) as a catalyst (based on 100 parts by weight The terephthalic acid is 0.3 parts by weight), and the temperature is slowly raised to about 170°C. Water began to be generated around 170°C, and the ester reaction was carried out at a reaction temperature of about 220°C under atmospheric pressure for about 4.5 hours while continuously feeding nitrogen, and when the acid value reached 0.01, the reaction was stopped.

[0044] After stopping the reaction, extractive distillation under reduced pressure was carried out for 0.5 hours to 4 hours to remove unreact...

Embodiment 1

[0046] In the reactor that is provided with stirrer, condenser and decanter, add 2000g diisononyl terephthalate and 340g n-butanol (based on 100 parts by weight DINIP being 17 weight parts) obtained in Preparation Example 1 parts), and then the resultant was subjected to a transesterification reaction at a reaction temperature of 160° C. for 2 hours under a nitrogen atmosphere, thereby preparing An ester-based plasticizer composition of butyl isononyl ester (BINTP) and 61.0% by weight diisononyl terephthalate (DINTP).

[0047] The reaction product was mixed distillation to remove butanol and 2-ethylhexanol and prepare the final ester-based plasticizer composition.

Embodiment 2

[0049] In addition to using 2000 g of diisononyl terephthalate and 340 g of isobutanol to finally prepare 5.0 wt % of diisobutyl terephthalate, 37.0 wt % of Except for the ester-based plasticizer composition of diisononyl terephthalate, the transesterification reaction was performed in the same manner as in Example 1.

Abstract

The present invention relates to an ester-based plasticizer composition, a method for preparing the same, and a resin composition containing the same. The ester-based plasticizer composition according to an embodiment of the present invention is a novel terephthalate-based ester compound for a plasticizer, prepared by a transesterification reaction, and the use of the composition for a resin composition can provide excellent resistance to stress, and excellent physical properties in view of tensile strength, elongation, migration resistance, volatility resistance, and the like.

Description

technical field [0001] This application claims priority and benefit from Korean Patent Application No. 10-2015-0067549 filed in the Korean Intellectual Property Office on May 14, 2015, the entire contents of which are incorporated herein by reference. [0002] The present invention relates to an ester-based compound, a composition comprising the same, a method for preparing the same, and a resin composition comprising the same, and in particular, to an ester-based compound comprising a terephthalate-based compound having three components. Plasticizer composition, method for its preparation and resin composition comprising same. Background technique [0003] Among common plasticizers, alcohols are reacted with polycarboxylic acids such as phthalic acid and adipic acid to produce their corresponding esters. Commercially important examples thereof include adipates of C8, C9 and C10 alcohols, such as bis(2-ethylhexyl) adipate, diisononyl adipate and diisodecyl adipate and phth...
