N.E.C. is the major manufacturer with a complete range of explosives and accessories, with factories in Scotland, Wales and England. Explosives and Chemical Products Ltd., with factories in England, is the other manufacturer of explosives for sale. The major commercial manufacturer of ammunition is Imperial Metal Industries (Kynoch) Ltd. at Witton near Birmingham. The British Government has of course a number of Royal Ordnance Factories and establishments to cover all aspects of military explosives.

In order to perform NMR studies on compressed supercritical steam, which exhibits a number of unusual properties, de Fries and Jonas developed an NMR probe working in the temperature range 25-700 °C and at pressures up to 200 MPa. The design of this probe, consisting of two high-pressure bombs, is given in Fig. 4.29. Both bombs have a 76 mm outer diameter and a 38 mm inner diameter and are made of IMI-680 titanium alloy (Imperial Metal Industries). The primary bomb at the top contains a furnace, the RF coil and two thermocouples. The sample extends from the ceramic tube in... 

Esterification ofTerephthalicAcid. Esterification of terephthaUc acid is also used to produce dimethyl terephthalate commercially, although the amount made by this process has declined. Imperial Chemical Industries, Eastman Kodak, Amoco, Toray, Mitsubishi, and Mitsui Petrochemical have all developed processes. Esterification (qv) generally uses a large excess of methanol in a Hquid process at 250—300°C. The reaction proceeds rapidly without a catalyst, but metal catalysts such as zinc, molybdenum, antimony, and tin can be used. Conversion to dimethyl terephthalate is limited by equiHbrium, but yields of 96% have been reported (75,76). 

Figure 13.14. A centrifugal packed fractionator, trade name HIGEE, Imperial Chemical Industries. Units have been operated with 500 times gravitational acceleration, with 3-18 theoretical stages, up to 36 in. dia, employing perforated metal packing. For distillation, one unit is needed for rectification and one for stripping. Units have been used primarily for gas stripping and on offshore platforms because of compactness [Ramshaw, Chem. Eng., 13-14 (Feb. 1983)].

Subsequently, to minimize corrosion and metallic copper deposits on the equipment walls, dilorine ions were superseded by those obtained from weaker organic acids (formic, acetic etc.) ICl process imperial Chemical Industries). 

The timing of this volume is appropriate. Last year was the 50th anniversary of Gibson and Fawcett s polymerization of ethylene, an accidental discovery that led eventually to the commercial manufacture of polyethylene by England s Imperial Chemical Industries. Parenthetically, Carl S. ( Speed ) Marvel made linear polyethylene with a metal catalyst 54 years ago. However, the opportunity presented by his discovery was not exploited by industry. 

The sodium reduction process is favoured by Imperial Chemical Industries Ltd. for the manufacture of titanium metal sponge. It was first operated commercially by their General Chemicals Division, at Wilton, but similar plants have since been installed in the United States. 

New promoted ammonia synthesis catalyst precursor composition contains metal oxides, e.g., iron, cobalt, aluminum, and specified alkali metal, prepared by precipitation and subsequent calcination. J. R. Jennings (Imperial Chemical Industries pic). EP200315 (1986) US 4689317 (1987).
