Liquid-Vapor Equilibrium in the Nitric Acid-Water-Praseodymium Nitrate--Neodymium Nitrate System

摘要

The liquid-vapor equilibrium was studied under pressure (101,325 +- 800 N/m exp 2 ) at 10, 20, 30, 45, 50, 60, 70, 80% salt. The dehydrating capability of Pr--Nd nitrate was found to lie between Mg(NO sub 3 ) sub 2 and La (NO sub 3 ) sub 3 . The equation was derived: 1/y = a + b (1/(x sub 1 - x sub 1 x sub 2 ) exp 2 ), where y = mass of nitric acid in vapor phase, x sub 1 and x sub 2 = masses of nitric acid and water in liquid phase.
