1,264,049. Phosphonopropionic acid amides. CIBA-GEIGY A.G. 1 Jan., 1970 [7 Jan., 1969], No. 121/70. Heading C2P. [Also in Division D1] The invention comprises compounds of formula where R 1 , R 2 , R<SP>1</SP> 1 and R<SP>1</SP> 2 are each C 1-4 alkyl, alkenyl or halogenalkyl, X and X<SP>1</SP> are each methyl or hydrogen, A is C 2 or C 3 alkylene which may be substituted by C 1-4 alkyl or alkoxy, or hydroxyl, Z is oxygen or sulphur and Y is C 1-4 alkyl, or hydrogen. The compounds of Formula I may be prepared by reacting (a) 1 mol. of a condensation product of 2 mols. of at least one compound (a<SP>1</SP>) of Formula II and one mol. of a compound (b<SP>1</SP>) of Formula III where the nitrogen atoms of component (a<SP>1</SP>) or component (b<SP>1</SP>) are monomethylolated and optionally etherified, with (b) 2 mols. of formaldehyde or of a formaldehyde releasing agent at elevated temperature, optionally in the presence of a basic catalyst, and optionally etherifying with 1 or 2 mols. of a C 1-4 alkanol (c). The products are used as flameproofing and creaseproofing agents for cellulosic fibre materials. |
