    Abstract: Brightener for textile was prepd. by mixing 0.05-lwt. % I [e.g.; R1, R2 = H; R3 = -COOC6H5, COOCH3, -CONH2, -COOH, -C(O)OCH2CH2OCH3, -CONR3, -CH3, -C6H4CH3, -C6H5, -C(O)NO, naphthalenyl, -C(O)O(CH2)11CH3 and 1-0.05wt.% II(e.g.; R4, R5, R6, R7 = H; X = 0;A1, A2 = -CH:CH-CH:CH-, -CH;C(COOH)-C(COOH): CH-, -CH:C(COOCH3)-C(COOCH3):CH-). When the polyester/cotton (50/50) textile was treated with brightener soln. which was contained 0.025 g/l I(R1, R2 = H; R3 = -COOC6H5) and 0.025g/l II(R4, R5, R6, R7 = H; X= 0; A1, A2 = -CH:CH-CH-), the brightness of Berger and Stenby was 136 and 137, resp.

    Abstract: 1399509 Bis-benzofuran derivatives HOECHST AG 11 Aug 1972 [13 Aug 1971] 37574/72 Heading C2C [Also in Division C3] The invention comprises compounds of the formula wherein A and A 1 each represents an aromatic, mono- or polynuclear ring system in which two adjacent C atoms are linked to the furan nucleus as indicated, R and R 1 each represents H, halogen, C 1 to C 4 alkyl, phenyl which may be substituted by C 1 to C 4 alkyl or alkoxy, halogen or COOH or SO 3 H or their functional derivatives, and B represents a continuously conjugated chain of C atoms, which may be completely or partly a constituent of a carbocyclic or heterocyclic ring system and which is conjugated with the adjacent double bonds of the two furan nuclei ; the ring systems A and A 1 may bear one or more non-chromophoric substituents. They may be obtained by (I) condensing intramolecularly a compound of the formula (II) condensing, intramolecularly, a compound of the formula wherein B 11 is a continuously conjugated chain of C atoms, (III) condensing, intermolecularly, a compound of the formula with a compound of the formula wherein D and E represent direct bonds or are continuously conjugated chains of C atoms which may be completely or partly constituents of a carbocyclic or heterocyclic ring system and which are conjugated with the adjacent double bonds of the furan nucleus, and R 6 represents an alkyl, cycloalkyl, aralkyl or aryl radical ; and (IV) condensing, intramolecularly, a compound of the formula whereby the radical B 11 migrates to the 2- position of the furan rings. Examples are given for the preparation of the compounds. They are useful as optical brightening agents. Compounds of Formula IV are obtained by reacting compounds of formula wherein M is an alkali or alkaline earth metal, with compounds of the formula wherein X is the anion of an inorganic acid.
