Abstract : A fuel composed principally of C11 to C14 hydrocarbons, JP-8, is too volatile to produce a persistent smoke cloud. Gas phase catalytic oxidation of the hydrocarbon components would yield new compounds (alcohols, carboxylic acids, and diols) that have lower vapor pressures. This report describes experiments to determine the merit of long chain alcohols for obscuration. Dodecanol (C12) produced effective smoke at ambient temperatures but was ineffective above 100 deg F. Decanol (C10) was less effective at ambient temperatures. Thus, it appears that the oxidation products of the C11 through C14 components in JP-8 will be useful for obscuration purposes. The program now shifts to identifying catalysts to effect the required oxidation without consuming the entire carbon chain. jg p.3
