Abstract: New saturated fluoroalkylamines and carboxyalkylbetaines and alkylsulfobetaines derived therefrom, and mixtures containing the new fluoroalkylamines and mixtures containing the new fluorobetaines are described. The saturated fluoroalkylamines conform to the formula below in which n is an integer from 3 to 17 and R1 and R2 are C1 to C4-alkyl, C1 to C4-hydroxyalkyl or hydrogen, with the proviso that only one of the two substituents R1 and R2 is hydrogen. The carboxyalkylbetaines and sulfobetaines and the mixtures thereof are highly effective products for reducing the surface tension of water/air systems and the interfacial tension of water/hydrocarbon systems.

Abstract: NEW BENZOFURAN DERIVATIVES, PROCESS FOR THEIR MANUFACTURE AND THEIR USE AS OPTICAL BRIGHTENERS of the disclosure: Furanyl-(2)-1,2,4-oxadiazoles of the formula wherein A represents an aromatic mononuclear or binuclear ring system which with two adjacent carbon atoms is fused with the furan nucleus in the manner indicated, R represents hydrogen, a lower alkyl group, an optionally substituted phenyl group, as well as an optionally functionally modified carboxy group, X represents a direct bond, as well as the following divalent radicals , , , , , , B represents a straight-chained or branched, optionally substituted alkyl group or an optionally substituted aryl or heteroaryl group. These compounds are suitable for the optical brightening of high molecular weight organic substances, especially for textile materials of synthetic polymers. - 1a

Abstract: NOVEL BENZOFURAN DERIVATIVES, PROCESS FOR THEIR PREPARATION AND THEIR USE AS OPTICAL BRIGHTENERS Compounds of the formula A (1) , in which A stands for aromatic mono- or polynuclear ring systems which are fused with the furan nuclei in the manner indicated above by means of two adjacent carbon atoms, R represents hydrogen or halogen atoms, lower alkyl groups, phenyl groups which are optionally substituted by lower alkyl, lower alkoxy groups or halogen atoms, as well as optionally functionally modified carboxy or sulfo groups, and D is a direct bond or a divalent aliphatic, aromatic or heteroaromatic connecting member continuing the conjugation, group A may be substituted by lower alkyl, alkenyl, alkoxy, aryl groups, preferably phenyl groups, optionally functionally modified carboxy or sulfo groups, acyl, acylamino or sulfonyl groups, as well as by halogen atoms. These compounds are valuable optical brighteners and can be applied by the methods known in this field.
