摘要:

AbstractThe use of nuclear magnetic resonance as the basis of a spectroscopic method in organic analysis is steadily growing.K. H. Hauser, Angew. Chem.68, 729 (1956).J. D. Roberts, Angew. Chem.75, 20 (1963); Angew. Chem. internat. Edit.2, 53 (1963).. The object of the present article is to present a general picture of the classification and interpretation of the NMR spectra obtained at high resolutions. In simple cases complete interpretation is possible with the aid of only a few equations; otherwise it is often necessary to use a laborious mathematical procedure, which is discussed here. For a more profound study, the reader is referred to more detailed publications.J. A. Pople, W. G. Schneider, andH. J.

摘要:

AbstractA brief account of the functions and chemical structures of the principal iron compounds found in the human body is followed by a discussion of the physiology of iron metabolism, starting with its resorption, continuing with its transport and assimilation by the body cells, and concluding with its elimination. Special attention is paid to the problems of intracellular and extracellular transport of iron. A number of diseases with characteristic disturbances of the iron metabolism are also briefly described.

摘要:

AbstractAcrylonitrile was produced in pilot plant from propylene, ammonia, and atmospheric oxygen in a fixed‐bed reactor in the presence of Bi/Mo/Si oxide shell catalyst. The propylene conversion, which can amount to about 70% under optimal conditions, was studied as a function of structural properties and the chemical composition of the catalyst, and of the composition of the starting mixture. Acrylonitrile of adequate purity for use in polymerizations could be obtained by multi‐stage processing of the crude prod

摘要:

AbstractEfficient processes have been developed in recent years for the large‐scale manufacture of alcohols from petrochemicals. These allow production of aliphatic alcohols both with short and with long alkyl groups more economically than was previously possible by fermentation. In this paper the most important principles and the technical execution of the hydration of olefins, the air oxidation of paraffins, and especially the synthesis reactions (e.g. the catalytic hydroformylation of olefins with carbon monoxide and hydrogen according to Roelen, the Reppe synthesis, and the Ziegler growth reaction with ethylene and triethylaluminum) are describe

摘要:

AbstractThe preparation of organic substances with the aid of the enzyme systems of micoorganisms has become competitive as a result of recent progress in the technology of fermentation. The relatively high cost of apparatus and the lower production capacity of microbiological plants in relation to the plants used in purely chemical processes are offset in many cases by the advantages of biological methods (reactions at conventionally inactive positions in the molecule, stereospecific substitutions, coupling of several reactions, mild reaction conditions, possible use of waste products).
