A process for the preparation of monovalent or divalent organo guanidinium salts is described. If the product is a monovalent organo guanidinium salt, the process comprises mixing together a halohydrocarbon, an inorganic base, and a salt of unsubstituted guanidine. If the product is a divalent organo guanidinium compound, the process comprises mixing together a first halohydrocarbon, an inorganic base, and a salt of unsubstituted guanidine, followed by mixing of a second halohydrocarbon with the mixture so formed; this is followed by the mixing of a third halohydrocarbon with the mixture formed from the mixing of the second halohydrocarbon. Both processes do not require the absence of water; the use of an organic solvent is optional.
描述了一种制备一价或二价有机胍盐的工艺。如果产物是一价有机胍盐,该工艺包括将卤代烃、无机碱和未取代胍盐混合在一起。如果产物是二价有机胍化合物,则工艺包括将第一卤代烃、无机碱和未取代的胍盐混合在一起,然后将第二卤代烃与这样形成的混合物混合;接着将第三卤代烃与第二卤代烃混合形成的混合物混合。这两种工艺都不要求没有水;有机溶剂的使用是可选的。
