Embodiment 1

[0060] In a 2-liter four-necked round-bottom flask equipped with a stirrer, a separation column for removing generated water, and a condenser, add 332.2 g of terephthalic acid and 781.2 g of 2-ethylhexanol, and add p-toluene 8.1 g of sulfonic acid was then passed through nitrogen gas at a rate of 100 ml / min while raising the temperature to 200° C. to carry out an esterification reaction to obtain a reaction product.

[0061] The total reaction time is about 6 hours, by GC-Mass analyzer (Gas Chromatography-Mass, gas chromatography-mass spectrometer) (Agilent 7890, stay at the initial temperature of 70 ° C for 3 minutes, and then increase the temperature at a speed of 10 ° C per minute to 280° C., and then stay for 5 minutes. Chromatographic column: HP-5, carrier gas: helium) As a result of analyzing the product, it was confirmed that the product was composed of 3.358% of two (2-ethylhexyl) ether, and 96.642% of the dioctyl terephthalate compound represented by the following che...

Embodiment 2

[0066] The same process was repeated except that the amount of p-toluenesulfonic acid used in Example 1 was replaced with 16.2 g.

[0067] After the reaction, the total reaction time was 4.5 hours. As a result of analyzing the product using a GC-Mass analyzer, it was confirmed that the product was composed of 3.505% of two (2-ethylhexyl) ether, and 96.495% of The composition of the dioctyl terephthalate compound represented by the chemical formula 1.

Embodiment 3

[0069] The same process was repeated except that the p-toluenesulfonic acid in said Example 2 was replaced with methanesulfonic acid.

[0070] The total reaction time was 10 hours. As a result of analyzing the product using a GC-Mass analyzer, it was confirmed that the product was represented by 6.563% of bis(2-ethylhexyl) ether and 93.437% of the product represented by the following chemical formula 1 Composition of dioctyl terephthalate compound.

Abstract

The present invention relates to a plasticizer composition comprising an ester plasticizer and an ether compound, and the improvement of processability and heat loss is proportional to the content of the ether compound.

Description

technical field [0001] The present invention relates to a plasticizer composition, specifically, to a plasticizer combination comprising an ester plasticizer and an ether compound, wherein the improvement of processability and heat loss is proportional to the content of the ether compound things. Background technique [0002] Typically, plasticizers are prepared by esterification reactions between acids and alcohols. At this time, as catalysts generally used in the esterification reaction, organic metal compounds including titanium compounds, tin compounds, etc.; ion exchange resins; zeolites; heteropolyacids; sulfuric acid and p-toluene Sulfonic acid etc. [0003] Among the various catalysts mentioned above, there are differences in the characteristics, reaction speed, and by-product generation of the catalysts. Taking this into consideration, it is necessary to use an optimal catalyst to carry out the esterification reaction for the synthesis of plasticizers. In the sel...
