British Oxygen

Materials NaGeX zeolite was kindly supplied by Dr. G. Poncelet (Universite Catholique de Louvain) and the mixed tin-antimony oxide catalysts (SnSbO) by I.C.I. Ltd. The H-Z is the acidified form of commercially available Norton mordenite. The ZSM-5 and ZSM-11 zeolites were synthesized following the patent literature (15,16). 1-Butene (Prochem) was a natural abundance compound, while methanol (95 % l C, British Oxygen Corporation (B.O.C.)), ethanol (95 % C, B.O.C.) and ethylene ( 90 % C, Prochem) were JC-enriched compounds. For the latter a 30 % v/v dilution was realized prior to adsorption. 

Hydrogen of 99.99% purity, supplied by the British Oxygen Company, was employed. 

Chemicals. Synthesis gas, as an equimolar mixture of carbon monoxide and hydrogen, was purchased from either Air Products Ltd or British Oxygen Company Ltd. Ru(acac)3 was purchased from Johnson Matthey Chemicals Ltd and used without further purification Ru3(C0)j2 Rh6(C0)i6 and Rh(C0)2acac were prepared according to literature procedures (10-12). Glacial acetic acid and the various additives/promoters were purchased from BDH Ltd and used without further purification. Tetraglyme (ex-Aldrich Chemical Company Ltd) was dried over activated 3A molecular sieves before use. 

Oxygen (British Oxygen Co., Ltd.) was obtained from cylinders and purified by fractionation from traps cooled to —196°C.

The Thermal Syndicate Ltd., makers of Vitreosil, recommend the British Oxygen Co. s No. 109616 lead welding torch for working tube up to 38 mm diameter, and the same company s No. 35069 lead welding torch for very small silica work. These torches burn oxy-hydrogen or oxy-propane. Oxy-coal gas may be used if the gas pressure is not less than 15.25 cm water gauge. 

Question by D. H. Tantam, British Oxygen Company, Ltd. The efficiencies given appear high, bearing in mind (1) the high gas inertia in the flow passages within the piston and (2) the throttling which occurs with piston-operated parts. Are the efficiency values for the gas expansion process alone, or for the overall machine ... 

Odda Smelteverk never used the process itself, however, but licenced it to I.G. Farben, Staatsmijneh of the Netherlands, as well as to Norsk Hydro. Odda stayed in its oldest businesses, that of producing calcium carbide and cyanamide. Neither did Odda s owner, the Hafslund group, use the Odda process. In 1937 it sold Odda Smelteverk along with the Odda process to the British Oxygen Company. 

It all benefitted Norsk Hydro, however. While Odda was completely honest about its technical knowledge, Norsk Hydro tried to circumvent the Odda process patent. After negotiations fell through in 1933, three leaders of Odda summed up their bitter experiences Norsk Hydro had not made any serious offer, but seemed to have wanted to postpone the matter and to get hold of all possible information, information that is now used to circumvent the Odda process. " " Even though Norsk Hydro clearly exploited the economic difficulties of Odda at the time, it is possible to understand why, since Odda s real plans had been to collaborate with American Cyanamid Company, in all probability as a competitor to Norsk Hydro. In any case, Norsk Hydro was in a very vulnerable position itself, also hit by the crisis it was only in 1929 that it completed restructuring to produce nitrogen fertiliser by the Haber-Bosch process. In the end, Odda did very little. Odda Smelteverk was sold to the British Oxygen Company in late 1937, and the Odda process was licenced to I.G. Farben in 1938, to Dutch Staats Mijnen in 1939, and eventually to Norsk Hydro after the war.
