Abstract

Munitions become obsolete due to expiration of their shelf life, storage or inappropriate conditions during use. In this study, it was aimed to recover and purify RDX from waste Composition-B (Comp-B) explosive, which is a mixture of 2,4,6-trinitrotoluene (TNT), hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX), which is the most commonly used as the main fusing agent in military munitions. Waste Comp-B samples were obtained from the munition in two different ways and different RDX recovery percentages and purity were achieved. Comp-B was obtained both mechanically directly from the ammunition and from the recycling process by melting the main filling of the ammunition with hot water and steam method. TNT was removed from the samples obtained by both methods by utilizing the solubility differences of TNT and RDX in Toluene and RDX was obtained (rRDX). The recovery efficiency was 94% for Comp-B obtained by the mechanical method and 77% for the hot water/steam melting method. As a result of the subsequent purification process, RDX purity for both methods was calculated as It was determined to be more than 99%.

Kullanım Ömrünü Tamamlamış Mühimmatlardan RDX Geri Kazanımının Araştırılması

Abstract

Mühimmatlar, raf ömürlerinin dolması, depolama veya kullanım esnasında uygun olmayan koşullarda muhafaza edilmesi sebebiyle kullanım dışı kalmaktadır. Bu çalışmada, askeri mühimmatlarda ana imla maddesi olarak en fazla kullanılan ve 2, 4, 6-trinitrotoluen (TNT), heksahidro-1, 3, 5-trinitro-1, 3, 5-triazin (RDX) karışımı olan atık Komposizyon-B (Comp-B) patlayıcısından RDX’in geri kazanımı ve saflaştırılması amaçlanmıştır. Atık Comp-B numuneleri mühimmattan iki farklı yol ile elde edilmiş ve farklı RDX geri kazanım yüzdelerine ve saflığına ulaşılmıştır. Comp-B hem mekanik yolla direk mühimmat bünyesinden, hem de mühimmatın ana dolgusunu sıcak su ve buhar yöntemi ile eriterek geri dönüşüm prosesinden elde edilmiştir. Her iki yöntem ile alınan numunelerden TNT ve RDX’in toluen içerisindeki çözünürlük farklılıklarından yararlanılarak TNT uzaklaştırılmış ve RDX elde edilmiştir (rRDX). Geri kazanım verimi, mekanik yöntemle elde edilen Comp-B için % 94 iken, sıcak su/buhar ile eritme yöntemi için % 77 olarak hesaplanmıştır. Daha sonra uygulanan saflaştırma işlemi sonucunda, her iki yöntem için RDX saflığı % 99’dan daha fazla olduğu belirlenmiştir.
