Subsidiary topics

THE CHEMICALS 400 is our unique grouping of the biggest, most successful corporations in all segments of the chemicals, coatings and plastics industry. Tens of thousands of pieces of information, gathered from a wide variety of sources, have been researched and are presented in a unique form that can be easily understood. This section includes thorough indexes to THE CHEMICALS 400, by geography, industry, sales, brand names, subsidiary names and many other topics. (See Chapter 4.)... 

The latter is outside the scope of organometallic chemistry, but within the first two topics the work involved three main themes olefin and acetylene complexes, alkyl and aryl complexes, and hydride complexes. As continuous subsidiary themes throughout ran the complex chemistry of tertiary phosphines and such ligands, the nature of the trans effect, and the nature of the coordinate bond. All the work from 1947 to 1969 was carried out in the Butterwick Research Laboratories, later renamed Akers Research Laboratories, of Imperial Chemical Industries Ltd., and I am indebted to that Company and particularly to Mr. R. M. Winter, the Company s Controller of Research, and Sir Wallace Akers, its Director of Research, who in 1947, made available to me the opportunity to develop my research in my own way, in those laboratories. 

Radial distributions determine the energy of an electron in an atom. As the average distance from the nucleus increases, an electron becomes less tightly bound. The subsidiary maxima at smaller distances are not significant in hydrogen, but are important in understanding the energies in many-electron atoms (see Topic A3). 

Since the topic of this book deals particularly with agglomeration it was found, however, that in Australia, India, the Near East, South America as well as Africa and in many smaller countries, sources of agglomeration equipment are primarily local subsidiaries or foreign and home office representatives of those that are mentioned in the list below. Other sources are international engineering companies, their local subsidiaries and representatives which are specifying and using European, North American, and Japanese equipment.
