    Abstract: Thiophene azo dyes I … … where the substituents have the following meanings:… R = cyano or C1-C4-alkoxycarbonyl; R = halogen; C1-C6 alkyl whose carbon chain may be interrupted by one or two oxygen atoms in ether function; C1-C6-alkoxy or C1-C6-alkylthio which may each carry phenyl as substituent; phenylthio or phenylsulphonyl which may each carry halogen, C1-C4-alkyl or C1-C4-alkoxy as substituents; R = cyano; C1-C4-alkanoyl, benzoyl, C1-C4-alkylsulphonyl or phenylsulphonyl; R = hydrogen; cyano; C1-C4-alkoxy which may carry hydroxyl or C1-C4-alkoxy as substituents; C1-C4-alkoxycarbonyl, aminocarbonyl, mono- or di- C1-C4-alkylaminocarbonyl; R = hydrogen; C1-C4-alkyl or C1-C4-alkoxy which may each carry hydroxyl, C1-C4-alkoxy or C1-C4-alkanoyloxy as substituents; C1-C4-alkanoyloxy which may carry hydroxyl, chlorine, cyano, C1-C4-alkoxy or phenoxy as substituents; C1-C6-alkanoylamino which may carry hydroxyl, chlorine, cyano, C1-C4-alkoxy, phenoxy or C1-C4-alkanoyloxy as substituents; benzoylamino which may carry chlorine, cyano, nitro, C1-C4-alkyl, C1-C4-alkoxy, C1-C4-alkoxycarbonyl or C1-C4-alkylsulphonyl as substituents; C1-C4-alkoxycarbonylamino or di-C1-C4-alkylaminocarbonyloxy whose alkyl groups may be bonded together to form a 6- or 7-membered ring containing the nitrogen atom of the amino group; R = hydrogen; C1-C10-alkyl whose carbon chain may be interrupted by one to three oxygen atoms in ether function and which may carry hydroxyl, halogen, cyano, C1-C4-alkanoyloxy or C1-C4-alkoxycarbonyl as substituents; C3-C5-alkenyl which may carry hydroxyl, halogen, C1-C4-alkoxy or C1-C4-alkanoyloxy as substituents; R = hydrogen; halogen; cyano; one of the alkyl groups R of the type defined; C1-C4-alkoxy; amino or mono- or di-C1-C4-alkylamino; R = one of the radicals R . … The thiophene azo dyes I are chiefly used as disperse dyes for dyeing textile material, in particular polyesters.

    Abstract: Stabilised aqueous C14- to C22-alkyldiketene emulsions containing, as essential components, (a) 10 to 60 % by weight of at least one C14- to C22-alkyldiketene, (b) 1 to 10 % by weight of at least one protective colloid and (c) 0.1 to 20 % by weight of at least one ester of the formula in which R , R are C14- to C22-alkyl, in which case R and R must differ in the alkyl group by at least 4 C atoms, and/or denote identical or different C14- to C22-alkenyl groups, an ester of the formula R -O-CO-O-R (II), in which R and R are alkyl or alkenyl radicals having 2 to 22 C atoms or a urethane of the formula in which R , R and R are identical or different alkyl or alkenyl radicals having 2 to 22 C atoms, and the use of the compounds of the formula I to III as stabiliser for the preparation of alkyldiketene emulsions containing at least 10, preferably 16 to 40 % by weight of alkyldiketene in emulsified form.

    IPC: C07D277/66

    Abstract: The invention relates to a process for the preparation of compounds of the general formula I in which R to R independently of one another denote hydrogen, alkyl, alkoxy, hydroxyl or halogen, which is characterised in that compounds of the formula II are reacted with compounds of the formula III in the presence of sulphur or sulphur-releasing compounds at elevated temperature. The compounds prepared according to the invention are suitable, for example, as diazocomponents.
