专利号:US-4698446-A 优先权日:1986-07-01 标题:Synthesis of polyamines and mixture formed thereby, of diprimary polyalkylene polyamines with disubstituted N-adjacent terminal carbon atom(s) 发明人:LAI JOHN T; SON PYONG N 权利人:GOODRICH CO B F 摘要:A nitroamine is formed from an aliphatic amine reactant + a nitroalkane + an aldehyde with better conversion, and faster, if the aldehyde is added last, and gradually, so as not to form an alkanolamine intermediate with the aldehyde as in the prior art reactions. In particular, a diamine such as ethylene diamine (EDA) has the unique ability, even among diprimary amines, to react with nitroalkane, to form a salt intermediate to which is added an essentially solvent-free aldehyde such as paraformaldehyde to produce a reaction product consisting essentially of a mixture of (i) a mononitrodialkylenediamine with a disubstituted N-adjacent terminal C atom and (ii) a dinitrotrialkylenediamine with each N-adjacent terminal C atom being disubstituted; and the mixture is obtained in an yield of at least 90 mol %.

专利号:US-7713401-B2 优先权日:2007-08-08 标 题 :Methods for performing electrochemical nitration reactions 发明人:LISTER TEDD EDWARD; FOX ROBERT VINCENT 权利人:BATTELLE ENERGY ALLIANCE LLC 摘要:A method for the electrochemical synthesis of dinitro compounds is disclosed. The method comprises using an anode to oxidize an inactive chemical mediator, such as a ferrocyanide (Fe(CN) 6 −4 ) ion, to an active chemical mediator or oxidizing agent, such as a ferricyanide (Fe(CN) 6 −3 ) ion, in the presence of a differential voltage. The oxidizing agent reacts with a nitro compound and a nitrite ion to form a geminal dinitro compound. The anode may continuously oxidize ferrocyanide to regenerate active ferricyanide, thus keeping sufficient amounts of ferricyanide available for reaction.
