PROCEDURE

实验过程

Nitrogen is produced as a result of the reaction between phosphorus pentoxide (P2O5) and fuming nitric acid (HNO3). P2O5is placed in flask 12. Fuming nitric acid is placed in dropping funnel 14 and is slowly dropped into the P2O5 in flask 12. Hafnium tetrachloride is placed in flask 20, with stirring bar 22, and is cooled using liquid nitrogen bath 26. When fuming nitric acid is dropped into flask 12 and quickly reacted with P2O5, N2O5 is produced, and condensed into flask 20. When sufficient N2O5 is generated, flask 20 is disconnected from flask 12, and warmed up to about 30° C. After refluxing in N2O5 for a while, e.g., about 30 minutes, hafnium nitrate is produced in high yield. P2O5+2HNO3→N2O5+2HPO3  (5) 4N2O5+HfCl4→Hf(HNO3)4+4NO2Cl  (6)
