The following new compounds were prepared from cyanoguanidine or guanylurea as potential flame retardants for cellulosic textiles -2-cyano-1-[bis-(dimethylamino)phosphinyl]guanidine, 2-cyano-1-(diethoxyphosphinyl)guanidine, and 2-carbamoyl-1-(diethoxyphosphinyl) guanidine. The successful phosphorylation of guanylurea required use of a dry, aprotic solvent.
以下新化合物是从氰胍或脲胍制备而成的,作为纤维素纺织品的潜在阻燃剂:2-氰基-1-[双-(二甲氨基)磷基]胍胍,2-氰基-1-(二乙氧基磷基)胍胍和2-氨基-1-(二乙氧基磷基)胍胍。成功对脲胍进行磷酸化需要使用干燥的无极性溶剂。
