标题 :Process for the synthesis of azobenzene compounds having a cyano group in one or both of the ortho positions of the diazo component radical
发明人：BUECHELER PAUL
权利人:SANDOZ LTD
摘要:A process for the synthesis of an azobenzene compound having a cyano group in one or both of the ortho positions of the diazo component radical comprising reacting the corresponding azobenzene compound having a chloro, bromo or iodo substituent in one or both of the ortho positions of the diazo component radical with a copper thiocyanate or copper thiocyanate-forming mixture of salts in the presence of an oxidizing agent (e.g., oxygen and sodium perborate), whereby the or at least one of the chloro, bromo and iodo substituents is replaced by a cyano group.

标题:New water-insoluble azo dyes
发明人：DEFEO FRANCESCO; CIPOLLI ROBERTO
权利人:ACNA
摘要:The present invention relates to the synthesis of new dyes having the following general formula: wherein: D is the residue of a diazotizable component of the carbocyclic or heterocyclic series X is an ethylene group, optionally substituted by halogen-methyl, alkyl C1-C4, aryl, aralkyl or CH2OCO(HN)nR (wherein R and n have the meanings hereinafter defined); R is alkyl C1-C8 optionally substituted by halogen, CN,COOH; aryl optionally substituted by one or more atoms of halogen, alkyl C1-C4, alkoxyl C1-C4; alkoxyl C1-C4; alkoxyl C1-C8; Aryloxy; aralkoxy; cycloalkoxy; aralkyl; naphthyl optionally substituted by halogen; alkenyl C2-C8, optionally substituted by halogen, CN, COOH; R1 and R2, either like or unlike each other, may be alkyl C1-C4 optionally substituted by halogen or CN groups; aralkyl; R3 is H; halogen, alkyl C1-C4; alkoxyl C1-C4, optionally substituted. n is 0 or 1.

标题 :Process for preparation of azo dyestuffs by coupling in presence of aromatic sulphonic acid-formaldehyde reaction product
发明人：MOLLS HANS-HEINZ; SCHIWY WILLY; HORNLE REINHOLD; NEBELING REINHARD
权利人:BAYER AG
摘要:Dyestuff dispersions and dyestuff solutions free from salt or at least having a low salt content are obtained in that the diazotization is carried out with addition of free dispersing agent acid to which, after the synthesis, either no basic agents are added or basic agents are added only up to a pH value of 3. The disclosed process gives dyestuff compositions of low salt content and results in readily dispersible dyestuffs when water insoluble dyestuffs are prepared and stable solutions when water soluble dyestuffs are prepared. The process is widely applicable and chemical constitution of the dyestuffs is conventional.
