Abstract
4 : 41 - Diaminodiphenylsulphone derivatives which are soluble in water and which are less toxic than the parent material are obtained by treating 4 : 41-diaminodiphenylsulphone containing at least one unsubstituted amino group with an acetaldehyde disulphonic acid or a salt thereof. One of the amino groups may, if desired, be substituted by the residue of an acid such as acetic acid or carbamic acid. In examples: (1) the disodium salt of acetaldehyde disulphonic acid is reacted with 4-amino-41-acetylaminodiphenylsulphone in aqueous alcoholic solution; (2) the barium salt of acetaldehyde disulphonic acid is reacted with sodium sulphate in aqueous solution and the resulting sodium salt reacted with 4 : 41-diaminodiphenylsulphone.
