    摘要: A pre-catalyst is formed by reacting butylethylmagnesium with an alcohol to form a magnesium alkoxide compound, followed by contacting the magnesium alkoxide compound with a phosphorous compound to form a magnesium alkoxide phosphorous compound mixture. The magnesium alkoxide phosphorous compound mixture is subsequently reacted with TiCl4 to form a MgCl2 support. The MgCl2 support is then contacted with an internal donor while being heated to form a first catalyst slurry, which is then contacted with TiCl4 while being heated to form a second catalyst slurry. The second catalyst slurry is next contacted with TiCl4 while being heated to form a third catalyst slurry, which is washed and dried, resulting in a highly active pre-catalyst with controlled morphology. The pre-catalyst may be combined with one or more co-catalysts and optionally one or more external electron donors to form an active catalyst system, which may be used for the polymerization of olefins.

    摘要: A method for the oxidative coupling of hydrocarbons, such as the oxidative coupling of methane to toluene, includes providing an oxidative catalyst inside a reactor, and carrying out the oxidative coupling reaction under a set of reaction conditions. The oxidative catalyst includes (A) at least one element selected from the group consisting of the Lanthanoid group, Mg, Ca, and the elements of Group 4 of the periodic table (Ti, Zr, and Hf); (B) at least one element selected from the group consisting of the Group 1 elements of Li, Na, K, Rb, Cs, and the elements of Group 3 (including La and Ac) and Groups 5-15 of the periodic table; (C) at least one element selected from the group consisting of the Group 1 elements of Li, Na, K, Rb, Cs, and the elements Ca, Sr, and Ba; and (D) oxygen.

    摘要: It has been discovered that using di-sec-butyldialkoxysilanes, such as di-sec-butyldimethoxysilane (DSBDMS), as external electron donors for Ziegler-Natta catalysts can provide a catalyst system that may prepare polypropylene films with improved properties and processing. The catalyst systems of the invention provide high activity, high bulk density, moderate hydrogen response, moderate donor response and high polydispersity (MWD). Suitable di-sec-butyldialkoxysilanes have the formula (SBu)2Si(OR″)2, where R″ is independently a straight or branched alkyl group of 1–5 carbon atoms.
