SOLID STATE CHEMICAL REACTIONS (WITH SPECIAL REFERENCE TO THE KINETICS OF THE REACTION OF INORGANIC OXIDANTS WITH POLY-DIVINYLBENZENE)
Abstract
The heterogeneous reaction in the solid phase of various high melting organic substances with solid oxidants in the presence of catalysts was investigated. The oxidants were KClO4, KBrO3, KNO3, KClO3, KIO3, chloranil and SeO2. The substrates were polycyclic aromatic compounds and polymers, in particular a co-polymer of p-divinylbenzene and p-ethylstyrene. A large number of high-melting substances, including inorganic salts, oxides, and metal powders were tried as catalysts. Generally, Lewis acids (Al2(SO4)3, FeCl2, etc.) catalyzed the reaction, while basic substances (Na2CO3, LiOH, etc.) inhibited it. The empirical equation dx/dt = k (a-x)/x to the 2nd power/3 fitted the kinetic curves for the catalyzed KClO4, KIO3 and KBrO3 oxidations of pDVB; and the zero order equation dx/dt = k fitted the kinetic data for the catalyzed KClO3 oxidation of pDVB.
