Even in the case of an organometallic compound par excellence, namely ferrocene, the situation is somewhat confused. The most extensive study of the electronic spectrum of this molecule is that of Scott and Becker (75), and the main observed bands are given in Table III where N— V denotes... 

TAMREAC is part of a wider study being developed by our group (5a-5d) and by others (6). This effort attempts to take advantage of the best characteristic of the computer relieving the chemist of the burden of some repetitive tasks so that he may concentrate on tasks in which he excells, namely, creation of new steps and reactions, selection of the most sensible mechanistic schemes, and selection of the most lively materials to illustrate his lectures. 

Clinical trials show that patients who adhere to a low-calorie diet and take orlistat lost on average 9-10 kg after one year (compared to 6 kg in those who took placebo) in the following year those who remained on orlistat regained 1.5-3.0 kg (4-6 kg with placebo). Orlistat has found a place in the management of obesity in the UK but, not surprisingly, this is subject to stringent guidance from the National Institute for Clinical Excellence, namely that it be initiated only in individuals ... 

If the leaving group is excellent, namely N=N in diazonium ions, an Sis[l-like path may occur. The many mechanisms for substitution on these diazonium ions are complex some involve electron transfer, radical intermediates, or copper catalysis (Chapter 11). 

Nastasya Petrovna An excellent name that. My aunt, my mother s sister, is also called Nastasya Petrovna. And what is your name she asked. You are probably a tax-assessor ... 

Homologous mono-alkyl ethers of ethylene glycol, such as monoethyl glycol (or 2-ethoxyethanol), HOC2H4OC2H5, form excellent solvents as they combine to a large extent the solvent properties of alcohols and ethers. The monoethyl and the monomethyl members have the technical names of ethyl cellosolve and methyl cellosolve respectively. Dioxan... 

This recrystallised acid is pure in the norm y accepted sense of the word, namely it has a sharp m.p. and gives on analysis excellent values for carbon, hydrogen and nitrogen. If however it is subjected to one-dimensional paper chromatography (p. 53), the presence of traces of unchanged anthranilic acid can be detected, and repeated recrystallisation is necessary to remove these traces. 

An excellent manostat, based on the Cartesian diver principle, is marketed under the name of Cartesian manostat. 

On the whole it is better to employ the activated decolourising charcoal prepared from wood. Excellent decolourising carbons are marketed under the trade names Norit (from birch wood), Darco and Nuchar. ... 

The last-named reaction provides an excellent method for the preparation of a-substituted glutaric acids the intermediate alkyl (aryl) -2-cyanoethyl-malonate is both hydrolysed and decarboxylated re ily by boiling with an excess of 48 per cent, hydrobromic acid solution. 

There have been many more basis sets developed, but the list above enumerates the most widely used ones. Some of these sets were the work of many different authors and later improved. This sometimes results in different programs using the same name for two slightly different sets. It is also possible to combine basis sets or modify them, wliich can result in either poor or excellent results, depending on how expertly it is done. How to customize basis sets is discussed in Chapter 28. 

Because the chemical stmcture of poly(phenylene sulfide) [9016-75-5] (PPS) does not fall into any of the standard polymer classes, the Federal Trade Commission granted the fiber the new generic name of Sulfar. The fiber has excellent chemical and high temperature performance properties (see... 

Nylon-11. Nylon-11 [25035-04-5] made by the polycondensation of 11-aminoundecanoic acid [2432-99-7] was first prepared by Carothers in 1935 but was first produced commercially in 1955 in France under the trade name Kilsan (167) Kilsan is a registered trademark of Elf Atochem Company. The polymer is prepared in a continuous process using phosphoric or hypophosphoric acid as a catalyst under inert atmosphere at ambient pressure. The total extractable content is low (0.5%) compared to nylon-6 (168). The polymer is hydrophobic, with a low melt point (T = 190° C), and has excellent electrical insulating properties. The effect of formic acid on the swelling behavior of nylon-11 has been studied (169), and such a treatment is claimed to produce a hard elastic fiber (170). 

Electrical Properties. Polysulfones offer excellent electrical insulative capabiUties and other electrical properties as can be seen from the data in Table 7. The resins exhibit low dielectric constants and dissipation factors even in the GH2 (microwave) frequency range. This performance is retained over a wide temperature range and has permitted appHcations such as printed wiring board substrates, electronic connectors, lighting sockets, business machine components, and automotive fuse housings, to name a few. The desirable electrical properties along with the inherent flame retardancy of polysulfones make these polymers prime candidates in many high temperature electrical and electronic appHcations. 

Many methods for chemical synthesis of a-amino acids have been estabUshed. Because excellent reviews have been pubUshed (25,38), weU-known reactions are introduced here only by their names and synthetic pathways. 

Carboxjiates with a fiuorinated alkyl chain ate marketed by the 3M/Industrial Chemical Products Company under the trade name Fluotad surfactants. They also include other functional derivatives of fiuorinated and perfluorinated alkyl chains. Replacement of hydrogens on the hydrophobe by fluorine atoms leads to surfactant molecules of unusually low surface tension. This property imparts excellent leveling effectiveness. 

This article discusses the main diseases caused by protozoa and the important chemotherapeutic antiprotozoal agents currently ia use or ia an advanced state of development. Not all alternative proprietary names are given for each dmg. There are excellent sourcebooks on protozoology and parasitology (2—8). 

Tetrachloroethylene [127-18-4] perchloroethylene, CCl2=CCl2, is commonly referred to as "perc" and sold under a variety of trade names. It is the most stable of the chloriaated ethylenes and ethanes, having no flash poiat and requiring only minor amounts of stabilizers. These two properties combiaed with its excellent solvent properties account for its dominant use ia the dry-cleaning iadustry as well as its appHcation ia metal cleaning and vapor degreasiag. 

Wood Preservation. The use of chromium compounds ia wood preservation is largely because of the excellent results achieved by chromated copper arsenate (CCA), available ia three modifications under a variety of trade names. The treated wood (qv) is free from bleeding, has an attractive ohve-green color, and is paintable. CCA is widely used, especially ia treating utility poles, bull ding lumber, and wood foundations. About 62% of all the chromic acid produced ia the United States is consumed by the wood preservation industry (77,167) (see Building materials, survey). 

Mordant dyes have hydroxy groups in their molecular stmcture that are capable of forming complexes with metals. Although a variety of metals such as iron, copper, aluminum, and cobalt have been used, chromium is most preferable as a mordant. Alizarin or Cl Mordant Red 11 [72 8-0] (1) (Cl 58000), the principal component of the natural dye obtained from madder root, is the most typical mordant dye (see Dyes, natural). The aluminum mordant of alizarin is a well-known dye by the name of Turkey Red and was used to dye cotton and wool with excellent fastness. However, as is the case with many other mordant dyes, it gave way to the vat or the azoic dyes, which are applied by much simpler dyeing procedures.
