The invention concerns a process of preparation of the polyazido alcohols by reaction of a polysubstituted oxirane having in position .beta. a nucleofuge group with a metal nitride, characterized in that the reaction is performed in an aqueous medium. The oxirane formula is: ##STR1## in which X represents a nucleofuge substituent, R1 represents an atom of hydrogen, a lower alkyl group substituted or not by a halogen, an aryl group possibly substituted, R2 and R3 represent an atom of hydrogen, a lower alkyl radical possibly substituted, an aryl group possibly substituted, R4 represents an atom of hydrogen, a lower alkyl group possibly substituted, an aryl group possibly substituted by an alkoxy group. Application to the preparation of polyamino alcohols, ureas, polyazidothiols and binding compositions for propergols.
本发明涉及一种制备多氮杂醇的方法,通过将具有位于β位置的亲核离子基团的多取代环氧烷与金属氮化物反应,其特征在于反应在水性介质中进行。环氧烷的化学式为:##STR1## 其中X代表亲核离子取代基,R1代表氢原子,一个低级烷基取代物或未取代的卤代烷基,可能取代的芳基基团,R2和R3代表氢原子,可能取代的低级烷基基团,可能取代的芳基基团,R4代表氢原子,可能取代的低级烷基基团,可能由烷氧基取代的芳基基团。应用于制备多氨基醇,脲,多氮杂硫醇和适用于推进剂的粘合组合物。
