Two-dimensional double metal cyanide complexes: highly active catalysts for the homopolymerization of propylene oxide and copolymerization of propylene oxide and carbon dioxide.
The synthesis of two-dimensional double metal cyanide complexes of the formula Co(H2O)2[M(CN)4].4H2O (M=Ni, Pd or Pt) and the X-ray crystal structure of Co(H2O)2[Pd(CN)4].4H2O are presented. The anhydrous forms of these complexes were found to be effective catalyst precursors for the homopolymerization of propylene oxide as well as the random copolymerization of propylene oxide and carbon dioxi...
متن کاملInterplay of reversible chain transfer and comonomer incorporation reactions in coordination copolymerization of ethylene/1–hexene
Coordinative chain transfer polymerization (CCTP) has opened a new path for the development of novel products like olefin block copolymers and chain-end functional polyolefins. However, conflicting results are frequently reported on the catalyst performance including activity and comonomer selectivity under CCTP conditions. Here we have selected two catalysts including rac-ethylenebis(1-η5-inde...
متن کاملThe Effect of 1-Butanol Co-Feeding on Propylene Production in the MTP Reaction
The propylene production with 1-butanol co-feeding for methanol in relation to propylene process (MTP) at 440-490 ̊C temperature range and at 0.9-15 hr-1 WHSV range over H-ZSM-5 zeolite catalyst is assessed in a isothermal fixed-bed reactor. The feedings here are of: pure 1-butanol, pure methanol and a 1-butanol and methanol mixture. The effect of 1-butanol co-feeding on selectivity of propylene...
متن کاملPropylene polymerization to high molecular weight atactic polypropylene and copolymerization with 1-hexene using monocyclopentadienyl titanium catalysts.
A number of cyclopentadienyltitanium aryloxide complexes, 1-Ar-2,3,4,5-Me(4)-Cp(2,6-(i)Pr(2)C(6)H(3)O)TiCl(2) (Ar = 4-Me(3)SiPhenyl (5), 4-(i)PrPhenyl (6), 4-MePhenyl (7), 3,5-(CF(3))(2)Phenyl (8)) and (1-Ar-2,3,4,5-Me(4)CpTiCl(2))(2)(OAr'O) (Ar' = 4,4'-(3,3',5,5'-(i)Pr(4)C(6)H(2)-C(6)H(2)), Ar = 4-SiMe(3)Phenyl (9), 4-MePhenyl (10)) were synthesized from the reaction of a corresponding cyclope...
متن کاملStructure and reactivity of propylene on clean and hydrogen-covered Pd(1 1 1)
The adsorption of propylene on clean and hydrogen-covered Pd(1 1 1) has been studied by using temperatureprogrammed desorption (TPD) and reflection-absorption infrared spectroscopy. Propylene adsorbs in a di-r configuration on clean Pd(1 1 1). At high exposures, it forms second and subsequent layers. Upon heating, propylene desorbs molecularly at 200 and 280 K and, in contrast to ethylene adsor...
