Bis(dinitroalkyl)acetals and formals having the formula (1)
particularly bis(2,2-dinitropropyl)acetal and bis(2,2-dinitropropyl)formal are produced by oxidative nitration of compounds having the formula (2):
preferably via a sodium or other alkali metal, or alkaline earth metal, salt of compounds of Formula (2). Certain of the compounds of formula (1) are novel. All of the intermediates of formula (2) are novel and form another aspect of this invention, as does a process for their production by reacting an aldehyde with a nitroalkanol. The process can readily produce a mixture of the dinitro compounds known as BDNPA and BDNPF (also known as A/F) using the non-explosive intermediates, BNPA and BNPF, both of which are novel.
具有公式(1)的Bis(二硝基烷基)乙缩醛和缩甲醛,特别是Bis(2,2-二硝基丙基)乙缩醛和Bis(2,2-二硝基丙基)缩甲醛,通过化合物的氧化硝化制备,该化合物具有公式(2)的化合物,优选通过化合物的钠或其他碱金属或碱土金属盐的方式制备。公式(1)中的某些化合物是新颖的。公式(2)的所有中间体都是新颖的,并构成本发明的另一个方面,还包括通过将醛与硝基醇反应制备它们的过程。该过程可以轻松地使用非爆炸性中间体BNPA和BNPF(均为新颖化合物)产生BDNPA和BDNPF(也称为A / F)的二硝基化合物混合物。
