PROCEDURE

实验过程

Halstead (J. Appl. Chem., 1970, 20:129-132) describes the decomposition of ammonium sulfate at 400° C. The first reaction converts ammonium sulfate to ammonium bisulfate and ammonia. In a second reaction, the ammonium bisulfate dehydrates to form a water molecule and ammonium pyrosulfate, (NH4)2S2O7. Further heating of the ammonium pyrosulfate to form sulfur dioxide and nitrogen, which are not desired products from ammonium sulfate, is also carried out.
