Spectroscopic studies of explosives

Spectroscopic studies of explosives. 1. Detection of nitro compounds on silica gel and carbon by nonresonant Raman spectroscopy. Carver, F. W. S.; Sinclair, T. J. (Minist. Defence, RARDE, Sevenoaks TN14 7BP, UK). J. Raman Spectrosc., 14(6), 410-14 (English) 1983. CODEN: JRSPAF. ISSN: 0377-0486.There are some commonly used reagents with their cas registry numbers 121-82-4 and 55-63-0 in this article. DOCUMENT TYPE: Journal CA Section: 50 (Propellants and Explosives) Raman spectra were obtained from trace amts. of nitroglycerin [55-63-0], PETN [78-11-5], RDX [121-82-4], and TNT [118-96-7] adsorbed on silica gel and on activated charcoal. The detection limits for these nitro compds. were 1-10 mg on silica gel and 20-40 ng on activated charcoal. .

Oxidative pretreatment accelerates TNT metabolism in soils

Oxidative pretreatment accelerates TNT metabolism in soils. Kearney, Philip C.; Zeng, Qiang; Ruth, John M. (Agric. Environ. Qual. Inst. 7659-29-2 and 108-73-6 are also occured in this study., Beltsville Agric. Res. Cent., Beltsville, MD 20705, USA). Chemosphere, 12(11-12), 1583-97 (English) 1983. CODEN: CMSHAF. ISSN: 0045-6535. DOCUMENT TYPE: Journal CA Section: 4 (Toxicology) The combined effect of UV light and ozonation of aq. 14C-labeled TNT (I) [118-96-7] solns. followed by direct addn. of the solns. to aerobic soils was examd. as a method of disposal. The effect of TNT concn. was studied on both UV-O3 and soil metab. The amt. of TNT degraded by either process decreased as the concn. increased. UV-O3 of a 1-ppm soln. of TNT using a lab. 450 W lamp for 10, 20, and 30 min resulted in substantial fragmentation of the ring and an increase in polarity of the resultant products. Soil metab., as measured by metabolic CO2 evolution, increased as the time of prior UV-O3 increased. A large amt. of the 14C assocd. with [14C]TNT recovered from soil was in the nonextractable fraction. When a Pseudomonas putida, adapted to metabolize o-nitrophenol or picric acid as a sole source of C and N, was substituted for the soil phase, ~25% of the added 14C appeared as 14CO2. 1,3,5-Trinitrobenzene [99-35-4], 2,4,6-trinitrobenzaldehyde [606-34-8], 3,5-dinitrophenol [586-11-8], 3,5-dinitrocatechol [7659-29-2], 3,5-dinitrohydroquinone [13985-45-0], and oxalic acid [144-62-7] were identified as products of UV-O3. Rapid destruction of TNT took place in a large 66 lamp unit, and the resultant distribution of 14C was similar to the results from the lab. studies. .
