Abstract
A p-dimethylaminobenzenesulfonate (MSE) polycrystalline powder is converted to the zwitterionic product p-trimethylammoniumbenzenesulfonate (ZWT) by a chemical thermally induced reaction at T=55,5 degrees C. Experimental resu lts obtained by differential scanning calorimetry and C-13 solid-stare NMR indicate that reaction-induced stress gives rise to a ferroelastic lattice instability during the thermally enhanced solid state reaction of methyl p- dimethylaminobenzenesulfonate (MSE).
