Abstract:

Octylferrocene is often used as a burning rate catalyst for solid rocket propellants because of its excellent catalytic performance and good compatibility. However, so far, there is no its reference material, which makes it difficult to trace and unify the magnitude of the weapons and equipment quality monitoring process, and the quality of related products can not be guaranteed. The reference material of n-octylferrocence in relative purity greater than 99.5% was prepared from industrial product as primary substance by re-crystalization from mixed solvent at low temperature, and its uniformity and stability was investigated by gas chromatography. The purity of n-octylferrocence reference material was certified by the method of mass balance. Other homologues were controlled by self-contrast method. The result shows that the certified result is 99.6% and the expanded uncertainty is 0.2%(k=2).

Key words: n-octylferrocene, certified reference material, mass balance method, uncertainty
