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... 

The pyrolysis properties of four model compounds were examined. Their molecular structures are shown in Table II. The three and four-ring molecules, containing a benzo [b] thiophenic unit were synthesized by Dr. Cagniant (L.S.C.O., Metz University). A polycyclohexanesulfide is an aliphatic sulfide synthesized by Dr. N. Spassky (Laboratory of Macromolecular Chemistry, Paris VI University). Polymeric aromatic sulfide was represented by a polybenzosulfide provided by Philips Petroleum.

P. pastoris was first described by Guilliermond as Zygosaccharomyces pastori [8], and named P. pastoris by Phaff [9]. The first isolate worldwide was from the exudate of a chestnut tree in France (strain CBS704, NRRL Y-1603, [8]). For long, only few isolates existed, of which the strain NRRL Y-11430 (CBS7435), isolated from black oak tree in California, was developed as a platform for single-cell proteins by Philips Petroleum. This strain then served as the basis for the development of the protein production system [10]. 

Rexene Co. and Philips Petroleum Co. first developed the bulk polymerization process with the first-generation TiCU catalyst [8,11,70]. It was then commercialized by Dart Industries in 1964. The reactor feed contains 10-30% propylene in the liquid phase. A mixture of hexane and isopropanol was employed for the removal of catalyst residue as well as the amorphous polypropylene. The process step of removing residual catalyst was later eliminated after the high-efficiency catalyst was adopted, constituting the so-called liquid pool process. Subsequently, Philips and Sumitomo companies further developed the liquid-phase polymerization process. This process enhances the reaction rate, catalyst efficiency, monomer conversion, and therefore results in high productivity. It also eliminates the need for solvent recovery and reduces environmental pollution. However, the process is somewhat complicated by the unreacted monomer, which has to be first vaporized and then liquefied before it is reused. The reaction vessel must be designed to operate under high pressures. In most cases, this process employs autoclaves for batch operation and tubular reactors for continuous operation. 

The first industrial metathesis of propylene was introduced by Philips Petroleum in 1966 (two years after the discovery of the metathesis reaction) and termed the triolefin... 

As a result of the relatively high cost of cycloolefins, large-scale metathesis leading to polymers is not utilized for these alkenes. Philips Petroleum also applies metathesis of Me2C = CHCMe3 with an excess of ethylene to synthesize CH2 = CHCMe3, which is employed in the perfume industry.
