aromatic ring, was evaluated over three of the prepared rod-like Fe–Al composite oxides (FeAl-1, FeAl-5 and FeAl-10). The results showed that their reactive activities were in the order of FeAl-5 ≈ FeAl-10 ≫ FeAl-1, which could be attributed to their different pore structural properties and reactive sites caused by the different phase interaction between iron species and the γ-Al2O3. The generation of
在制备的三种棒状Fe-Al复合氧化物(FeAl-1,FeAl- 5和FeAl-10)。结果表明,它们的反应活性约为FeAl-5≈FeAl-10≫ FeAl-1,这可能归因于它们的孔结构性质和反应位点不同,这是由于铁物种与γ-之间的不同相间相互作用引起的。 Al 2 O 3。三氯萘(1,2,3-TrCN和1,2,4-TrCN,即CN-13和CN-14),二氯萘(1,2-DiCN,1,3-DiCN,1,4-DiCN)的生成和2,3-DiCN,即CN-3,CN-4,CN-5和CN-10)和一氯萘(1-MoCN和2-MoCN,即CN-1和CN-2)提示发生了连续的加氢脱氯反应。在三个不同的系统中,CN-14的含量从CN-13的71.5%增至77.7%,这表明在β位置发生了第一个加氢脱氯步骤是优选的。这与八氯萘(CN-75)脱氯过程中在微/纳米Fe 3 O 4上观察到的在α-位置的偏好不同。。一侧和

Die Erfindung betrifft ein halogenhaltiges Copolycarbonatgemisch. das verbesserte kritische Dicke und verbesserts Flammwidrigkeit und Feuerwiderstandsfähigkeit aufweist und das Reaktionsprodukt eines aromatischen Diphenols, eines aromatischen Thiodiphenols und eines Kohlensäurederivats wie Phosgen oder Carbonylbromid in Mischung mit einer wirksamen Menge einer halogenhaltigen Verbindung enthält. Bei einer bevorzugten Ausführungsform enthält das Copolycarbonatgemisch außerdem geringe Mengen wines Perfluorsulfonsäure- oder -carbonsäuresalzes.
An organic halide activator component is used in combination with a halogen-free organoammonium molybdate or tungstate catalyst and a halogen-free trialkylaluminum cocatalyst in the ring-opening metathesis polymerization of norbornene functional monomers. The activator component is characterized by having 1 or 2 halogen substituents per molecule with the proviso that said halogen substituent(s) is not bonded to a carbon that contains a double bond. The organic halide activators of this invention enhance the conversion of monomer to polymer without the corrosion problems inherent with prior activated metathesis catalytic systems.
