Abstract: 1384091 N-Substituted diamine-maleic acid semi-amide adducts HOECHST AG 3 March 1972 [5 March 1971] 9989/72 Heading C2C [Also in Division C5] Anti-microbially active compounds having surface-active properties are of formula in which R 1 is C 8-18 alkyl or alkenyl, x is 2 or 3, and R 2 and R 3 are (where Y is H or an alkali metal) or one of R 2 and R 3 may be hydrogen, or are in the form of the corresponding betaine, and are prepared by reacting one or more compounds with maleic acid semi-amide or a salt thereof in an aqueous or aqueous alcoholic medium. Use of the ammonium salt gives the compounds in betaine form. Alkali metal salt products can be converted to the betaine form by treatment with an acid to a suitable pH. The ammonium salt of maleic acid semiamide is prepared from maleic anhydride and gaseous NH 3 in chloroform.
