Katz method

Thus, 4,5-benzo-3-thiatricyclo[4.1.0.02 7]heptene (46), which is regarded as a valence isomer of benzo[8]thiepin (4), appears to be an attractive precursor to 4. The most obvious method for the synthesis of 46 would be the application of the elegant Katz method 37> to the benzvalene synthesis. The well established success of the preparation of 43 36) by the Katz method makes this a likely route to 46.

The parameters A, B, and C are dependent on the particular nature of the gas. Katz developed a simple method for gas mixtures that takes the composition of the gas into account [942,1086]. Furthermore, a graphic method is available that permits the estimation of the hydrate-forming temperatures at pressures for natural gas containing up to 50% hydrogen sulfide [129].

The tetracycline which may be present is then converted to an anhydro derivative by heating in acid and is measured spectrophotometrically. Feldman et al. (84) developed the alkaline degradation method to measure CTC in fermentation mash and Spock and Katz (85) used this method to determine CTC in animal feed premixes.

Saidel and Katz (97) have used an extension of the method of moments to calculate MJMn for a batch polymerization with transfer to polymer, and with termination exclusively by combination, but with restriction to mono-radicals. As the equations for the second and higher moments contain terms involving still higher moments it is necessary to approximate them in terms of lower moments, but this requires assumptions about the form of the distribution that may not be justified.

There are many methods of hardness testing, fairly widely used, depending on tradition and laboratory equipment. Moreover, the materials to be tested vary in nature owing to their particular structure, chemical properties and texture. A proper choice of test method for a given type of materials is therefore a fundamental problem in petrotechnical estimation of materials, rocks and products of their technological processing, chiefly ceramic materials (Katz and Lenoe, 1976).
