Abstract | Title cpds. are of formula (I):- (where R1 and R2 are H or CH3; R3-R6 and R8 are H or 1-4C alkyl; R7 is 8-18C alkyl or alkenyl; n is 2 or 3; m is 0-4; when m is 1-4, R2 is H and when m is 0, R3 and R4 must be H if R1 and R2 are CH3, and R4 must be H if R3 is propyl or butyl), e.g. phosphorous acid 3- 2-(2-dodecylaminoethyl)-aminoethylammonium -2:2-dimethylpropyl ester. They are obtd. by reacting corresp. substd. cyclic phosphites with amines at 60-150 degrees C. |
