Phillips Insoluble

The process implications of equation 3 go beyond the weU-known properties (27—29) of NMP to faciUtate S Ar processes. The function of the aminocarboxylate is also to help solubilize the sulfur source anhydrous sodium sulfide and anhydrous sodium hydrogen sulfide are virtually insoluble in NMP (26). It also provides a necessary proton acceptor to convert thiophenol intermediates into more nucleophilic thiophenoxides. A block diagram for the Phillips low molecular weight linear PPS process is shown in Eigure 1. [Pg.442]

The first step in the biochemical analysis of the receptor, isolation from the cell membrane, was difficult the membrane-associated protein is present in only small amounts and is insoluble in aqueous solution. Sensitivity and selectivity would be improved by radiolabeling under conditions that maintain cell viability so that only proteins associated with the surface and not those within the cell become labeled. A procedure that met these conditions was iodination catalyzed by lactoperoxidase in the presence of hydrogen peroxide (Marchalonis, 1969 Phillips and Morrison, 1970 Marchalonis et al., 1971). It was also necessary to find conditions for solubilizing membrane proteins that would not interfere with subsequent specific immunoprecipitation. [Pg.55]

See Table 1 of the 1956 paper by Clark, Hogan, Banks, and Lanning, Ind. Eng. Chem. 48,1152, which contained this statement about the earliest polypropylene made from Phillips catalyst "Contains a solid fraction, insoluble in hydrocarbons, which is identical in X-ray diffraction and infrared absorption to the isotactic polymer described by Natta."... [Pg.137]

In the Phillips process, polyphenylene sulfide (PPS) is obtained from the polymerization mixture in the form of a fine white powder, which, after purification, is designated Ryton V PPS. Characterization of this polymer is complicated by its extreme insolubility in most solvents. At elevated temperatures, however, Ryton V PPS is soluble to a limited extent in some aromatic and chlorinated aromatic solvents and in certain heterocyclic compounds. The inherent viscosity, measured at 206°C in 1-chloronaphthalene, is generally 0.16, indicating only moderate molecular weight. The polymer is highly crystalline, as shown by x-ray diffraction studies (9). The crystalline melting point determined by differential thermal analysis is about 285°C. [Pg.92]

Poly(p-phenylene sulfide) was first reported in 1897 by Genvresse [92] who reported an insoluble resin prepared by the reaction of benzene with sulfur in the presence of aluminum ehloride. A variety of other procedures were reported to yield similar resins. Macallum [93] in 1948 reported a novel procedure that yielded an improved resin. Lenz and co-workers [94-96] modified the procedure and Edmonds and Hill [97] of the Phillips Petroleum Co. developed a commercially successful process. The material is now marketed under the trade name Ryton [98]. The crystallinity of the polymer has recently been reported [99-101]. [Pg.103]

Desmaison et al. conducted studies on Arabian crudes and noted the emulsion formation was correlated with two factors - photo-oxidation exposure and amount of asphaltenes (16). The photo-oxidation was found to occur on the aromatic fractions of the oil. Asphaltenes were found to become structured with time and this was associated with emulsion formation. Miyahara reported that the stability of emulsions was primarily controlled by the composition of the oil, specifically that which resided in flie hexane-insoluble fraction of the oil, but he did not define what fliis content was (17). Miyahara also reported that salt and freshwater emulsions showed relatively similar stabilities, alfliough in one case the salt-water emulsion appeared to be more stable. Payne and Phillips reviewed the subject in detail and reported on their on experiments of emulsification wifli Alaskan cmdes in fire presence and absence of ice (18). Their studies showed fliat emulsion formation could occiff in an ice field, thus indicating that fliere was sufficient energy in this environment and that the process could occur at relatively low temperatures. [Pg.410]

Slurry polymerization is often used in the manufacture of polyolefins. Initially, the reaction system consists of the catalyst dispersed (or dissolved as in the case of soluble metallocene catalysts) in a continuous medium, which may be a diluent in which the monomer is dissolved or pure monomer. The polymer is insoluble in the continuous medium, therefore it precipitates on the catalyst forming a slurry. High-density polyethylene (HOPE) is produced in a slurry of isobutane (Chevron-Phillips process) [22 ]. Liquid propylene is used in the Spheripol process to produce i-PP [22]. [Pg.18]
