In the investigation of any chemical reaction, the main points of interest are the conditions of equilibrium, the rate at which equilibrium is approached, and the mechanisms by which the reaction occurs. The first of these is determined by the standard free energy change, a thermodynamic quantity which depends only upon the initial and final states of the system. However, two reactions having the same value of the standard free energy change may approach equilibrium at radically different rates, one being practically instantaneous and the other almost infinitely slow. The field of chemical kinetics is concerned with the study of …

No exchange work prior to this dissertation has been reported on the Americium system. Neptunium exchange is presently being studied by J. C. Hindman and co-workers at the Argonne National Laboratory, but has not been completely reported. Study of uranium exchange, which is still in an unsatisfactory state, has been limited to the U(IV)-(VI) exchange.

In 1953 Cook, Hewett, and Rieger found a highly carcinogenic hydrocarbon in coal tar. By a variety of solvent extraction methods, fractional distillation, and crystallization several pure hydrocarbons were isolated from the crude pitch. Two new pentacyclic aromatic hydrocarbons were isolated and since only small quantities of them were available it was decided to ascertain their structures by synthesis instead of degradetive experiments. The hydrocarbon samples were obtained with great difficulty from two tons of crude pitch. The problem was simplified since ten of the possible fifteen pentacyclic hydrocarbons were known. From certain similarities of these hydrocarbons to perylene its …
