| titleOfInvention | N-SULFOALKAN AMINOALKANE PHOSPHONIC ACIDS, THEIR ALKALINE SALT AND METHOD FOR THEIR PRODUCTION |
| abstract | N-sulphoalkane-aminoalkanephosphoric acids are new cpds. of general formula R1C(PO3H2)(R2)NR3R4, where R1, is H, Me, Et, Ph, CH2NH2 or C2H4PO3H2; R2 is H or PO3H2; R3 is CnH2nSO3H or CH2PO3H2, n being 1-11; and R4 is H when R3 is not CH2PO3H2, or CnH2nSO3H. Alkali metal salts of these cpds. can be formed. They can be prefd. by reacting, in alkaline medium: (a) alkali metal salts of amino-phosphoric acids with: (b) chloroalkane-sulphonic or hydroxyalkane-sulphonic acids (or their alkali metal salts); or with: (c) cpds. having hydroxyalkane sulphonates; by heating in the molar properties 1:1 to 1:2. These acids are differentiated from known phosphonic acids in that H atoms on the N atoms are replaced by alkanesulphonic acid gps. They are easily prepd. in good yield, and have excellent solubility in aqs. media (>=100g/100ml). They complex well with bi- or multi-valent metallic ions, and have good resistance to hydrolysis, even above 100 degrees C. They can be used to counteract water hardness e.g. in textile treatment, paper making, and tanning. |
