| titleOfInvention | N-nitro-5-azidomethyloxazolidine-1,3 synthesis method |
| abstract | FIELD: chemistry. ^ SUBSTANCE: invention relates to a method for synthesis of N-nitro-5-azido-methyloxazolidine-1,3 which can be used as an energetic plasticiser for polymers. The starting compounds used are potassium sulphamate and epichlorohydrin. The reaction for bonding potassium sulphamate to epichlorohydrin takes place at 50Ç53C and holding time of 50Ç55 hours with threefold excess of potassium sulphamate. Without extraction, the formed N-(3-chloro-2-hydroxypropyl)-potassium sulphamate is condensed in form of a water-alcohol solution with formaldehyde and the water-alcohol solution of N-(5-chloro-methyloxazolidine1,3)-potassium sulphamate obtained after evaporation is suspended in acetic anhydride without extraction from the reactor and nitrated with nitric acid at 10Ç25C. The formed N-nitro-5-chloromethyl-oxazolidine-1,3 is extracted with organochlorine solvents, purified by treating with aqueous sodium hydroxide solution at 70Ç75C and undergoes azidation with sodium azide in dimethyl formamide medium in the presence of activated carbon at 100C. ^ EFFECT: improved method. ^ 1 cl, 5 ex |
