Preliminary Assessment of p-Nitro-N-Methylaniline as Stabiliser in CDB Propellants

Abstract

A review has been made of the results of tests on cast double-base propellants containing para-nitro-N-methylaniline (NMA) as a stabiliser. The review is based on 80 deg C Silvered Vessel (SV) tests and stabiliser consumption trials carried out at both ICI and ERDE. The available evidence shows that NMA is adequate as a replacement for 2-nitrodiphenylamine (NDPA) for some uses although not as good in ultimate stabilising power. An initial 1% minimum of NMA may be suitable as sole stabiliser in conventional double-base propellants but slightly more may be required for unfavourable compositions or where a Service Chemical Life much in excess of 10 years at 32 deg C is required. It is found that composite modified compositions require resorcinol in addition to NMA for adequate chemical stability. Clarification is needed of Land Service requirements to enable the required figures for Service Chemical Life to be specified.
