Use of the 'Markham' Semi-Micro Still for the Determination of Stabilisers in Propellants. Part 1. Determination of Ethyl Centralite at the 3-8% Level.

Abstract

The use of the 'Markham' semi-micro still in the determination of ethyl centralite in propellants is described. The new procedure gives results which compare well with those from the traditional steam distillation-gravimetric method, so that continuity can be assured for propellants undergoing extended accelerated thermal ageing. A determination can be completed within thirty minutes by the new method, compared with 24 hours by the existing method. The apparatus is more compact, and smaller amounts of sample and reagents are required. The ethyl centralite is determined by direct spectrophotometry of the steam distillate, thus eliminating solvent extraction and subsequent chemical operations involved in the gravimetric method.
