Abstract: A polyester film for being embossed with a laser-engraved pattern and a manufacturing method thereof are provided. The polyester film includes a substrate layer and at least one surface layer formed on the substrate layer. The surface layer serves as an easy-to-press embossed pattern layer, and is formed from a polyester-based copolymer. The polyester-based copolymer includes residues derived from a diacid component and residues derived from a diol component. The diacid component includes 85 to 95 mol % of terephthalic acid and 5 to 15 mol % of isophthalic acid. The diol component includes 35 to 74 mol % of ethylene glycol, 1 to 15 mol % of neopentyl glycol, and 25 to 50 mol % of 1,4-butanediol.

Abstract: A hydrogenation method for increasing the yield of cyclohexane-1,4-dicarboxylic acid diisooctyl ester is provided. The hydrogenation method uses a hydrogenating reaction tank, which is equipped with a hollow-shaft gas-introducing mixer having air-extracting, air-exhausting and mixing functions, to allow hydrogen gas to be uniformly dispersed in a reaction solution. A ruthenium-on-alumina (Ru/Al2O3) hydrogenation catalyst can be used for carrying out a hydrogenation reaction under gentle conditions. Therefore, the hydrogenation catalyst can be used in a reduced amount, the risk of side reaction(s) can be reduced, and the yield of cyclohexane-1,4-dicarboxylic acid diisooctyl ester can reach at least 99% with a cis isomer proportion of at least 85.0%. The hydrogenation method shows extremely high economic benefit.

Abstract: 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.
