Philips process

Catalysts used in the polymerization process. For example, commercial isotactic polypropylene is polymerized from a hetereogenous organo-aluminium-titanium complex (Ziegler-Natta process) [110,1260], or less frequently from metallic oxides of chromium, vanadium or molybdenum bonded to an inert support (e.g. the Philips process) [447]. Transition metal ion contents vary in different commercial samples (Table 2.4). [Pg.64]

The Phillips triolefin process [56] developed at Phillips Petroleum, used a heterogeneous WOj/SiOj catalyst in metathesis reaction to convert propene 127 into mixture of ethene 125 and 2-butene 126. As it is a reversible reaetion (Scheme 9.32) and the price of propene rose high, the reverse reaction of Philips process offered is now by using Lummus teehnology to produce propene known as Olefin Conversion Technology (OCT). [Pg.351]

Obviously, however, someone needs to do more research on that topic. I contacted Philip Brown and asked him about this topic. Unfortunately, linearity per se is not of interest to him the emphasis of the paper he wrote was on role of linearity in the wavelength-selection process, not the nonlinearity itself. Furthermore, in the years since that paper appeared, his interests have changed and he is no longer pursuing spectroscopic applications. [Pg.468]

Expose the solution to long wavelength UV light at about 365 nm (Philips TL 20W/09 UV light works well) for 10-30 minutes. The solution may be cooled on ice to prevent heating during the irradiation process. [Pg.533]

Two catalyst systems were developed by Standard Oil and Philips petroleum. Standard Oil process uses metal catalyst such as molybdenum trioxide on supports like alumina or titanium or zirconium dioxide. The process is carried out at 200-300°C at Organisation and Qualities... [Pg.150]

The nicotine content in tobacco from cigarettes sold worldwide shows a wide variation (lARC 2004). Counts and coauthors reported on the nicotine content in the tobacco tiller of 48 Philip Morris USA and Phihp Morris International commercial filtered cigarettes from numerous international market regions (Counts et al. 2005). The majority contained blends of bright flue-cured (Virginia), hurley air-cured, and sun-cured oriental tobaccos, with inclusions of expanded tobaccos, processed tobacco, or processed stems. Four cigarettes contained primarily bright tobaccos. Nine brands contained carbon (also known as charcoal ) in their filter construction. [Pg.66]
