Titrimetric Analysis of Han-Based Liquid Propellants

Abstract

Liquid propellants that are aqueous mixtures of hydroxylammonium nitrate (HAN) and triethanolammonium nitrate (TEAN) are analyzed using a combination of acid-base and Karl Fischer titrimetry, procedures that quantitatively determine the three major propellant components. The method developed converts HAN to acetoxime and nitric acid by reaction with acetone and then uses either tetrabutylammonium hydroxide or n-butylamine in ethanol or aqueous sodium hydroxide as titrant for both HAN and TEAN. Water is determined by Karl Fischer titration using the proprietary reagent Hydranal . Each major propellant component is, therefore, determined separately. Keywords: Liquid propellants, Triethanolammonium nitrate, Titrimetry, Butylamine, Hydroxylammonium nitrate.
