Preparation and catalysis of NaY-encapsulated Mn(III) Schiff-base complex in presence of molecular oxygen
The new NaY zeolite (DMY). whose cages’ size had been expanded, was used as supports for encapsulating the large Schiff-base complexes. The catalysts were used in the aerobic epoxidation of 1-octene. The catalyst showed high activity and selectivity for the substrate and products. These catalysts proved to be more active than other kind of metal ion or supports. The effect of temperature, or...

Studies on the phase separation of polyetherimide modified tetrafunctional epoxy resin. III. Morphology development of the blend during curing.
Using scanning electron microscope (SEM), differential scanning calorimetry (DSC) and time-resolved light scattering (TRLS) methods, the morphology development of novel polyetherimide modified tetreglycidyl-4,4'-diaminodiphenylmethane (TGDDM) epoxy resin was investigated. The phase separation took place early in the blend and morphology was fixed in the first 10 minutes of curing. Then, the diffus...

Synthesis and Characterization of Liquid Crystal Polyesters with T-Shaped Two-Dimensional Mesogenic Units(III)
A new series of liquid crystal polyesters with T-shaped two-dimensional mesogenic units were synthesized by melt polycondensation of the diacetates of 2-(4`-alkoxy-phenyl)-hydroquinones with 4,4`-alkylenedioxydibenzoic acid. The polymers were characterized by usin polarized microscopy,DSC and X-ray diffraction.It was relized that all the polymers have nematic thermotropic liquid crystalline charac...

Phenolic rigid organic filler/isotactic polypropylene composites. III. impact resistance property
A novel phenolic rigid organic filler (KT) was used to modify isotactic polypropylene (iPP). The influence of KT particles on the impact resistance property of PP/KT specimens (with similar interparticles distance, 1.8 μm) was studied by notched izod impact tests. It was found the brittle-ductile transition (BDT) of the PP/KT microcomposites took place at the filler content of about 4%, and the...

Synthesis of the complex of lanthanum (III) with N-(2-amino ethyl) maleamic acid radical and its application to PVC as thermal stabilizer
关键字：N-(2-amino ethyl) maleamic acid radical；Lanthanum (III)； Polyvinyl chloride (PVC)； Heat stabilizer； Thermogravimetric analysis (TGA)
The complex (LaL3) of lanthanum (III) with N-(2-amino ethyl) maleamic acid radical (L) was synthesized and characterized by Fourier infrared spectrum (FT-IR), elemental analysis and melting point measure-ments. The complex LaL3 was a chelate, in which lanthanum (III) ion was coordinated with the carboxylate oxygen and amide nitrogen atoms of N-(2-amino ethyl) maleamic acid radical (L). The sta...

聚苯乙烯负载氨基甘油对水中Au（III）的吸附性能研究
关键字：聚苯乙烯，3-氨基-1,2-丙二醇，吸附，Au(III)
作为稀有资源的金、铂等的回收利用一直受到人们的极大关注。由于树脂法提取金具有负载能力大、金的回收率高、解吸较易等优点，近年来吸附树脂在金的提取中的应用研究一直非常活跃。
