nitrated
1.Mono-substituted aromatic hydrocarbons were selectively nitrated with NO_2 in the presence of molecular imprinted polymers(MIPs).
2.Production manager: nitrated puerility control resulting in a reduction in working hours by 2028528le increasing pro-ductility by 25%.
3.Poirier Marc-Andre,Steere David E,Drogh James A.Cetane improver compositions comprising nitrated fatty acid derivatives[P].USP 5 454 842,1995-10-03.
4.A new method is developed to preparate HMX by nitrolysis of DPT with nitrating agent HNO_3-P_2O_5-NH_4NO_3.The content of HMX in HMX/RDX mixture obtained from the nitrated products were determined by means of Hitachi 635 type HPLC.
5.When anthraquinone (AQ) is nitrated by mixed acid or O 3 NO 2 system, different product distribution would be got. To give an explanation of it, density functional theory was used to investigate the two kinds of AQ nitration.
6.Acenaphthene is nitrated by fumic nitric acid,the resultant is then oxidized by diluted nitric acid(65%)to produce 6?7 dinitro 1H?3H naphtho[1?8 cd]pyran 1?3 dione(Ⅰ),which is condensed with 2?4 dimethylanilin to form 6?7 dinitro 2 (2′?4′ dimethyl)phenyl 1H benzisoquinolin 1?3(2H) dione(Ⅱ). The title compound is obtained by the reduction of Ⅱ with stannous chloride in acidic media.
7.Di-(3′-chlorostyryl)-2,4,6-trinitrobenzene,which may be used as the intermediate for the synthesis of new high explo-sives,is nitrated to form 1,3-di-(3′chloro-4′-nitrostyryl)-2,4,6-trinitrobenzene by HNO3-H2SO4.Oxygen content and explosive pow-er have been improved in molecular,and the meIting point has increased bv 71℃。
