Different methods for the preparation of high purity NaAlClare disclosed. The methods includes charging a feed having an intimate mixture of aluminum chloride, sodium chloride, and aluminum metal, to a reactor at an initial temperature less than about 80&#xb0; C., carrying out a solid state reaction to form a solid NaAlClat an intermediate temperature less than about 145&#xb0; C., melting the formed solid NaAlClat an elevated temperature greater than about 150&#xb0; C. to produce molten phase NaAlCl, holding the reactor at a raised temperature greater than about 165&#xb0; C. to substantially complete formation of colorless NaAlCland filtering the reactor contents at a final temperature greater than about 165&#xb0; C.

The present invention is generally directed to core/shell nanoparticles, wherein such core/shell nanoparticles comprise a nanoparticle core and a nanoshell disposed about the nanoparticle core such that, in the aggregate, they form a core/shell nanoparticle that is operable for use as an imaging agent in X-ray/computed tomography (CT). Typically, such core/shell nanoparticle-based X-ray CT imaging agents further comprise a targeting species for targeting the imaging agent to diseased sites. Included herein are methods for forming such agents, comprising forming an ensemble of core/shell nanoparticles, wherein the mean diameter of the ensemble of core/shell nanoparticles is selected so as to render the nanoparticles in the ensemble substantially clearable by a mammalian kidney.

An activation system for optical media in one embodiment includes a tag having at least one pair of conductors with at least one heating element coupled to the conductors. The heating element is oriented proximate one or more activation regions on the optical media, and wherein the heating element activates the optical media. The tag in one embodiment is an elongate flexible tag material with a number of conductors that couple on one end to heating elements wherein the heating elements are disposed within a media case such that they are proximate activation regions on a media article.

The present invention relates to an interfacial method of preparing ester-substituted diaryl carbonates. The method includes the steps of: forming a reaction mixture comprising phosgene, an ester-substituted phenol, an organic solvent, and a catalyst selected from the group consisting of a tertiary amine catalyst and a phase transfer catalyst, said reaction mixture having an organic phase and an aqueous phase, wherein said aqueous phase has a brine strength; allowing the reaction mixture to react wherein during the reaction, (i) the aqueous phase has a pH, and the pH is adjusted, if necessary, by the addition of an alkali metal hydroxide solution in amounts such that the pH is greater than or equal to 9.0 during at least some portion of the reaction, and (ii) the brine strength of the aqueous phase is adjusted, if necessary, by varying the concentration of the alkali metal hydroxide solution being added to maintain the pH such that the brine strength is between 15% and a saturated brine solution during at least some portion of the reaction: thereby forming an ester-substituted diaryl carbonate, wherein the reaction mixture is formed with less than 15% water of formulation, and wherein the brine strength is maintained at or above 15% and the pH is maintained at or above 9 for a sufficient portion of the process that the ester-substituted diaryl carbonate is formed with a conversion of at least 90% and a selectivity of at least 98%.

Method of preparing ester-substituted diaryl carbonates

An improved method for the preparation of ester-substituted diaryl carbonates prepared by reacting phosgene with recycle streams of ester-substituted phenols from reaction processes using a tetraalkyl ammonium hydroxide catalyst, a tetraalkyl phosphonium hydroxide catalyst, or both, where at least one alkyl group of the tetraalkyl ammonium hydroxide or the tetraalkyl phosphonium hydroxide is a methyl group. The improvement includes the step of treating the recycle stream to reduce the concentration of a trialkyl amine, trialkyl phosphine, or both, if present, from the recycle stream prior to reacting it with phosgene to form the ester-substituted diaryl carbonate.

A method is disclosed to prepare a polymeric material by filtering solutions of poly(arylene ether) and/or poly(alkenyl aromatic) through one or more filtration systems to provide a material having reduced levels of particulate impurities. The polymeric material prepared is suitable for use in data storage media applications.

Methods of preparing a polymeric material

A method of separating a polymer-solvent mixture is described wherein a polymer-solvent mixture is heated prior to its introduction into an extruder comprising an upstream vent and/or a side feeder vent to allow flash evaporation of the solvent, and downstream vents for removal of remaining solvent. The one-step method is highly efficient having very high throughput rates while at the same time providing a polymer product containing low levels of residual solvent.

Method of separating a polymer from a solvent

Methods to prepare a poly(arylene ether) and poly(alkenyl aromatic) polymeric material having reduced levels of particulate impurities are described. The polymeric material prepared is suitable for use in data storage media applications.

Methods of preparing a polymeric material composite

Polymer are removed from organic solvent-polymer mixtures by preparing a liquid-liquid dispersion of finely dispersed solvent droplets containing polymer in water, adding this liquid-liquid dispersion to a stirred vessel containing water or other suitable liquid and rapidly evaporating the solvent to produce a slurry of the polymer in a liquid from which the solid polymer particles are recovered.

Polycarbonate isolation through homogenization devolatization

A method for dispersing solid forms of additives in polymers involves adding dispersions or solutions of additive(s) to a solution of polymer in a tubular mixer (preferably in the presence of a stationary mixer). The mixer leads to a steam precipitation step wherein all fluid ingredients in the mixture are volatilized leaving the solid additive and resin in the desired ratio. This results in a uniform dispersion of the additives in the polymer matrix. As a result of the high dispersion, physical properties of a thermoplastic resin, to which the polymer matrix has been added are preserved. In one illustration, PTFE as a drip inhibitor additive, is added to polycarbonate to obtain a highly dispersed PTFE concentrate of improved-drip-inhibition without loss of mechanical properties when added to a thermoplastic molding resin.

Injection of even very small amounts of supplemental water to the spent-air stream at points upstream from the heat exchanger cooler(s) used in processing spent-air streams from a cumene-to-phenol process allows these heat exchanger coolers to act as both extractors and condensers. It is therefore possible to recover from the heat exchanger cooler a methanol/water condensate, thereby substantially reducing the amount of methanol in the spent-air stream prior to discharge. Thus, known methods for manufacture of phenol from cumene in which an oxygen-containing gas stream is passed through liquid cumene to produce an oxidate product and a spent-air stream comprising methanol and cumene and a saturating amount of water; and in which the spent-air stream is passed through one or more heat exchanger coolers and a carbon bed prior to discharge can be improved.
