摘要： A method for enhancing reaction efficiency of a terephthalate plasticizer involves using a homogenizer to fine PTA to slurry having a particle size of 80-110 μm, and esterifying the PTA slurry with a C6-C10 alcohol in the presence of a titanium-based catalyst. The reactivity is enhanced by more than 37.5%, and the terephthalate plasticizer so synthetized is low-odor and has a purity of more than 99.5% as well as good physical properties such as acid value, color, and index of refraction.

摘要： 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.

摘要： This invention relates to a process for preparing succinic acid and succinate ester from a succinic acid salt in fermentation broth. In the first stage of this invention, renewable carbon resources are utilized to produce succinic acid through biological fermentation. The succinic acid salt in the fermentation process is subjected to double displacement reaction with a strong acid leading to release of succinic acid. Succinic acid is recovered by fractional crystallization integrated with simulated moving bed chromatography to produce succinic acid and succinate ester.

摘要： A method for preparing an aromatic di-ester includes combining an aromatic di-acid and a linear or branched C4-C13 alcohol to form a mixture. The method also includes heating the mixture from a first temperature (T1) to a second temperature (T2) without a catalyst present in the mixture. The method further includes combining a titanium catalyst with the mixture after the mixture is at the second temperature (T2). The method further includes increasing pressure from a first pressure (P1) to a second pressure (P2) after the mixture is at the second temperature (T2). The method further includes increasing the temperature of the mixture from the second temperature (T2) to a third temperature (T3) while maintaining the second pressure (P2).
