  摘要：

  研究了具有不同电荷分离，刚性和形状的有机阳离子和阴离子的缔合常数，并将其与无机阳离子与有机阴离子的缔合常数以及无机离子的缔合常数进行了比较。Bjerrum的离子对形成理论适用于球形无机离子，但不适用于具有各向异性电荷分布和形状的离子。对于后者，电荷匹配成为缔合的重要因素，并且在离子为刚性离子时最有效。

  coordinated DEF molecules. Heating 1 to 400 °C provides a porous DEF-free MOF (3), as confirmed by thermogravimetric analysis (TGA), elemental analysis, powder X-ray diffraction (PXRD) and BET surface area. Remarkably, removing the coordinated DEF molecules from 1 while retaining the porosity might lead to the formation of open metal sites, which are favorable for the adsorption of various gas molecules

  Poly(butylene terephthalate) is prepared in a two-stage process wherein terephthalic acid and 1,4-butanediol are esterified in the presence of a catalytic amount of a catalyst having an organo-metallic component which is an organo-titanate compound, an organo-tin compound or a combination thereof and a salt component which is an organic acid salt or an inorganic salt. In a second step, the esterification product is subject to polycondensation. By following the foregoing procedure, the formation of tetrahydrofuran is significantly suppressed and the percent conversion of esterification products increased.

  Calcium aluminum hexahydrate is a useful curative-stabilizer for halogenated rubbers such as chloronated polyethylene, chlorosulfonated polyethylene and polychloroprene as it can yield vulcanizates free of leachable lead. Also, these vulcanizates with about 1 to about 30 or more parts with about 3 to about 15 parts calcium aluminum hexahydrate being highly desirable give satisfactory to improved heat ageing properties as well as oil ageing properties.
