THE THERMAL DECOMPOSITION OF PERCHLORIC ACID VAPOR
ATLANTIC RESEARCH CORP ALEXANDRIA VA
The thermal decomposition of perchloric acid vapor has been studied from 200 to 439 C. The reaction products over this temperature range have been found to be chlorine, water and oxygen. From 200 to 350 C the kinetics of the decomposition reaction have been studied by determining the rate of chlorine formation colorimetrically from 350 to 439 C the kinetics were determined by a flow system technique. The results of the kinetic measurements are interpreted in terms of a heterogeneous reaction at the lower temperatures and a homogeneous one at the higher temperatures. A mechanism for the homogeneous reaction is proposed. Author
