| titleOfInvention | Process for the production of organic sulphonic acids or their salts containing sulphur and nitrogen |
| abstract | The invention comprises substituted sulphonic acids and their salts, containing at least one dithiocarbamate residue which is disubstituted on the nitrogen and to which the sulphonic group is linked via an aliphatic residue, and at least one thiourea or thiosemicarbazide residue linked via an aliphatic residue containing 2-18 carbon atoms, and in which the sulphonic group or groups is or are in the nonacid esterification component or components of the dithiocarbamate ester residue or residues, especially those of the formulae <FORM:0990882/C2/1> <FORM:0990882/C2/2> where R1 and R2 are hydrogen, aliphatic, cycloaliphatic or araliphatic hydrocarbon residues, which may be linked together, interrupted by hetero-atoms or hetero-atom groups or be substituted, and in the second formula R1 and R2 may also be aromatic residues; R3 is a hydrocarbon residue which may be aliphatic, cycloaliphatic or araliphatic and may contain heteroatoms, hetero-atom groups and/or substitutents; R4 and R5 are alkylene residues; and X is hydrogen, a metal, or a salt-forming organic base. R1, R2 and R3 may also be linked to further thiourea, thiosemicarbazide or dithiocarbamic acid ester S-alkane sulphonic groups; the invention also comprises the production of such compounds by reacting an alkane polyamine containing at least one primary and at least one secondary amine group but no tertiary amine group with amounts of CS2 and alkali equivalent to the primary and secondary amine groups to produce an alkane polydithiocarbamate, further reacting this with an equivalent amount of a salt of a reactive haloalkane sulphonic acid or a sultone to produce an alkane polydithiocarbamate S-alkane sulphonate, further reacting this with an equivalent amount of ammonia or a primary or secondary aliphatic, cycloaliphatic or araliphatic amine or hydrazine and, if necessary, making alkaline with an alkali or, where an amine was used in the previous step, with excess amine, and isolating the resulting salt. Examples prepare the following compounds <FORM:0990882/C2/3> <FORM:0990882/C2/4> <FORM:0990882/C2/5> <FORM:0990882/C2/6> <FORM:0990882/C2/7> <FORM:0990882/C2/8> Many suitable reaction components are listed. Reference has been directed by the Comptroller to Specifications 764,340, 764,613 and 778,263. |
