摘要： Granules/pastilles of unadulterated brominated anionic styrenic polymer are prepared and provided. They are made by forming a downward plug flow from an orifice in a manifold or nozzle in proximity to a cooled traveling planar member. Such member is impervious to cooling liquid. There is a gap between the lower end of the orifice and the planar member. A portion of a plug of the molten polymer either (i) bridges such gap or (ii) freely drops from the orifice and falls upon the planar member, in either case forming an individual granule/pastille on the planar member and solidifies thereon. The traveling member is cooled by a mist or spray of cooling liquid applied to the underside of the planar member. The granules/pastilles have superior properties.

摘要： 4-Fluorobenzaldehyde is produced by a commercially feasible process. The process comprises heating a mixture of fluorobenzene and a strong Lewis acid with dissolved hydrogen halide in an atmosphere of carbon monoxide at about 45 to about 100° C. and at a total pressure of about 150 psig up to the maximum pressure rating of the reactor. Formed is a reaction mass containing a Lewis acid complex of 4-fluorobenzaldehyde and at least a halobis(fluorophenyl)methane by-product. The complex is broken by quenching the reaction mass with a Lewis acid-solvating liquid to liberate 4-fluorobenzaldehyde. By-product halobis(fluorophenyl)methane is converted to di(fluorophenyl)methanol to avoid potential corrosion problems and formation of light sensitive color bodies in the recovered 4-fluorobenzaldehyde.

摘要： A metallocene having one or two hydrocarbyl groups bonded to a Group 4 metal are produced from a crude impure pasty or non-wet mixture containing at least 50% by weight of a metallocene having two halogen atoms bonded to a Group 4 metal atom, by (a) mixing liquid aromatic hydrocarbon with the crude impure pasty or non-wet mixture; (b) mixing a solution of an organolithium compound in a suitable anhydrous ether or paraffinic hydrocarbon solvent or a mixture thereof, with the mixture from (a) and agitating the resulting mixture so that lithium halide solids are formed; and (c) separating the solids and recovering the resultant liquid portion which is mainly a solution of the metallocene having one or two hydrocarbyl groups bonded to a Group 4 metal. Additional optional steps include (d) replacing the original solvent from the solution from (c) with a liquid paraffinic hydrocarbon diluent to form a slurry of product solids; and (e) recovering the product metallocene solids. Preferred organolithium compounds have the formula, RLI.nLiX, where R is tert-alkyl, aryl, alkaryl, benzyl, or alkyl-substituted benzyl, or most preferably, methyl, and X is Br or I.

摘要： Bridged metallocene compounds are produced by a process of promising commercial utility for plant-sized operations. One of the key steps of the process involves converting a deprotonated silicon-, germanium- or tin-containing ligand into the metallocene. Preferably, and in accordance with an embodiment of the invention, this is accomplished to great advantage by adding a diamine adduct of a Group IV, V, or VI metal tetrahalide to a solution or slurry formed from a deprotonated silicon-, germanium- or tin-containing ligand and an organic liquid medium so as to form a metallocene. The overall process of the invention involves the direct conversion of benzoindanones to benzoindanols which, without isolation, are converted to benzoindenes. Thereupon the benzoindenes are bridged by deprotonating the benzoindenes with a strong base such as butyllithium and reacting the resultant deprotonated product with a suitable silicon-, germanium- or tin-containing bridging reactant such as dichlorodimethylsilane. The resultant bridged product is deprotonated with a strong base such as butyllithium and reacted with a suitable Group IV, V, or VI metal-containing reactant such as ZrCl.sub.4 to provide a silicon-, germanium- or tin-bridged Group IV, V, or VI metal complex, such as a dihydrocarbylsilyl-bridged zirconocene complex.

摘要： A continuous process for the hydrocarbylthiation of aromatic amines is disclosed. The process involves forming an admixture of aromatic amine, hydrocarbyl disulfide and an effective amount of a Lewis acid catalyst and subsequently allowing such admixture to flow as a thin film along a column. An inert gas is passed in a counter-current manner through the admixture. The liquid thiohydrocarbyl aromatic amine product is then separated from the gaseous effluent
