ESTER-BASED COMPOUND, COMPOSITION COMPRISING THE SAME, METHOD FOR PREPARING THE SAME AND RESIN COMPOSITION COMPRISING THE SAME (AS AMENDED)

The present invention relates to an ester-based plasticizer composition, a method for preparing the same and a resin composition comprising the same. The ester-based plasticizer composition according to one embodiment of the present invention is a novel terephthalate-based ester compound for a plasticizer prepared through transesterification. When the ester-based plasticizer composition is used in a resin composition, it is capable of providing excellent resistance for stress, and excellent physical properties such as migration resistance and volatility resistance as well as tensile strength and elongation rate.

Preparation method of low-melting-point mixture of diesters of terephthalic acid

The invention relates to a preparation method of terephthalate n-butyl.isobutyl ester and a preparation method of low-melting-point mixture of diesters of terephthalic acid. According to the preparation method, dimethyl terephthalate and mixed liquor of n-butanol and isobutanol are used as raw materials, and high-temperature-resistant acidic resin is used as a catalyst. The disadvantage that a product is hard to separate, separation processes are many, and there are lots of waste liquids in the prior art is overcome. Instruments and equipment used in the process by the method are simple. In addition, operation steps are simple, and yield of the target product is high.

Low-melting mixtures of di-n-butyl and diisobutyl terephthalate

Mixtures of terephthalate diesters having lowered freezing points and methods of making the terephthalic acid diesters. The method includes contacting a first alcohol, a second different alcohol and dimethyl terephthalate in the presence of a catalyst to thereby form the terephthalate diesters.
