09/659352

International Classification:

B01D 5000

US Classification:

95 92, 568749, 95228

Abstract:

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.

International Classification:

C08K 904

US Classification:

Abstract:

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.

Abstract:

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.

International Classification:

C08F006/10

US Classification:

528481, 528499, 528500, 528501, 528203

Abstract:

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.
