Compounds of the formulas ##STR1## WHEREIN: X represents oxygen or sulfur; Z represents the residue of a hydroxyl-containing moiety; R.sub.1 and R.sub.2 in formula (1) may be the same or different and individually represent alkyl, cycloalkyl or aryl and, together with the common nitrogen atom, represent a 5 or 6 member ring containing oxygen, sulfur or nitrogen or combination thereof; Nr.sub.1 r.sub.2 in formula (2) represents a 5 or 6 member ring containing oxygen, sulfur or nitrogen or combination thereof; n represents an integer having a value of 2 or greater and is equal to the number of hydroxyl groups on the orginal hydroxyl-containing moiety, the residue of which is now represented by Z. are prepared by reacting a phosphorohalidate with an amine in an organic solvent containing aqueous alkali metal or ammonium hydroxide. The compounds are useful as flame retardants for natural and synthetic materials.
根据以下公式制备的化合物:##STR1## 其中:X代表氧或硫;Z代表含羢基团的残基;公式(1)中的R.sub.1和R.sub.2可以相同也可以不同,分别代表烷基、环烷基或芳基,并且与共同的氮原子一起代表含氧、硫或氮或其组合的5或6元环;公式(2)中的Nr.sub.1 r.sub.2代表含氧、硫或氮或其组合的5或6元环;n代表一个整数,其值大于或等于2,并等于原含氢氧基团上的氢氧基团数量,其残基现在由Z代表。通过在含水碱金属或铵氢氧化物的有机溶剂中与胺反应来制备这些化合物。这些化合物可用作天然和合成材料的阻燃剂。
