(Basic properties of coals and other solids)
Two kinds of coal, CMEV Rawhide subbituminous obtained from Exxon and Illinois {number sign}6 obtained from the Argonne Coal Bank have been compared through their heats of immersion in a series of strong protonic acids and boron trichloride, a strong Lewis acid. There are generally good correlations between the heats of immersion values for the two coals with each other, and with previous measurements of the heats of immersion of polyvinylpyridine in the same acids. However, the heats of immersion in solutions of boron trichloride and benzenesulfonic acid are separated widely from the correlation lines. The liquid acids used in this study were also compared as bases through their heats of immersion in concentrated sulfuric acid. Two papers are in preparation and hopefully will be submitted during the coming quarter. 4 figs., 2 tabs.
