• (1) In the study of the equilibrium pressure of the CO<SUB>2</SUB>-NH<SUB>3</SUB>-Urea-H<SUB>2</SUB>O system, it was experimentally found that the equilibrium pressure of the system is a function of loading, density of reactants in the reaction vessel at a given temperature.<BR>(2) The experimental equations that show the relation between temperature and equilibrium pressure were studied at various loading densities, under conditions that loading mol ratio of carbon dioxide to ammonia was one by two, and at the temperature range 130° to 170°.<BR>(3) It was verified that the diversity of the equilibrium pressure of the system is reasonable.
