The Ziegler process, based on reactions discovered in the 1950s, produces predorninandy linear, primary alcohols having an even number of carbon atoms. The process was commercialized by Continental Oil Company in the United States in 1962, by Condea Petrochemie in West Germany (a joint venture of Continental Oil Company and Deutsche Erdid, A.G.) in 1964, by Ethyl Corporation in the United States in 1965, and by the USSR in 1983. 

This process is currentiy used by Vista Chemical, successor to Continental Oil Company s chemical business, and by Condea. In the Ethyl Corporation process dilute sulfuric acid is used in place of water in the hydrolysis step producing alum rather than alumina.

Mesitylene. One of the principal derivatives of mesitylene is the stericaHy hindered phenol of the stmcture shown in Eigure 4. Its trade name is Ethanox 330 and it is produced by Albemarle Corporation (formerly Ethyl Corporation) (31). Ethanox 330 is an important noncoloring antioxidant and thermal stabiHzer for plastics, adhesives, mbber, and waxes (qv) (32,33) (see Antioxidants). The oral toxicity of Antioxidant 330 is extremely low (oral LD q in rats >15 g/kg) since its large size, C H gO, effectively eliminates absorption from the gastrointestinal tract.

The major source of raw materials for the preparation of fatty amines is fats and oils such as tallow, and coconut, soya, and palm oils. Ethyl Corporation uses petrochemicals as raw materials to prepare alkyl dimethyl and dialkylmethyl tertiary fatty amines, trademarked as AE)MA and DAMA products, which can be suppHed as single-carbon chain-length cuts or custom blends (13). Commercially available high purity fatty amines are Hsted in Table 3. Cost of the amines can vary owing to supply of raw materials.

Facilities for manufactuting bromine are primarily located near sources of natural brines or bitterns containing usable levels of bromine. In 1990, the United States had seven bromine plants owned by four companies. Six of the plants are in southern Arkansas and are operated by two U.S. producers Great Lakes Chemical Corporation and Ethyl Corporation. 

The submitters used trimethylalane available in a cylinder from Ethyl Corporation. Both neat trimethylalane and its 2 M solution in toluene gave comparable results. The toluene solution of trimethylalane is also available from Aldrich Chemical Company.

The rubber has a very low of -68°C, excellent hydrolytic stability and excellent resistance to ozone, solvents and acids. In addition the rubber does not bum even in an oxidising atmosphere. Although its properties are virtually unchanged in the range -75 to + 120°C it does not possess the heat resistance of other fluoroelastomers. This polymer was marketed by Firestone in the mid-1970s as PNF rubber, but in 1983 the Ethyl Corporation obtained exclusive rights to the Firestone patents and the polymer is now marketed as Eypel F. 

A recently marketed fuel additive is MMT (methyl cyclopentadienylmanganese tricarbonyl). MMT was first developed by the Ethyl Corporation in 1957 as an octane enhancing agent and has experienced a growth in demand in the 1990s. MMT was Ethyl Corporation s first major new antiknock compound since TEL. 

Tetraethyllead fluid in four gasolines supplied by the Ethyl Corporation was determined by the comparative method on weighed samples, aluminum serving as standard. These tetraethyllead fluids could have contained dibromo- or dichloroethane, or both, in addition to the lead compound. 

The values of x in column 4 were obtained by the Ethyl Corporation by a chemical method, for which the estimated precision is 0.02 ml of tetraethyllead fluid per gallon. Comparison of columns 4 and 5 shows agreement within these limits for all samples except B62M-3 the reason for the considerably greater discrepancy here is unknown. The precision of the x-ray work is better than was expected. (The precision is sufficiently great to warrant consideration of the difference in the x-ray absorption of the base stocks, samples AOT-1 and B62M-1.) Further-...
