摘要

A thermodynamic analysis of CsHSO₄ in oxygen and hydrogen atmospheres has been carried out. In an oxygen atmosphere, the phase relationship for the dehydration of CsHSO₄ as a function of H₂O partial pressure was established. It is concluded that CsHSO₄ is stable in a humidified oxygen atmosphere, p_H2O
