摘要:The invention “Method for selective synthesis of N-methyl-para-anisidineâ€? relates to chemical technology processes, namely to catalytic alkylation of aromatic amines and nitro compounds. n The invention relates to the method for synthesis of N-methyl-para-anisidine (N-methyl-para-methoxyaniline; N-methyl-para-amino anisole) from para-anisidine (para-amino anisole; para-methoxyaniline) or para-nitro anisole (1-methoxy-4-nitrobenzene) and methanol in the presence of hydrogen or without hydrogen on heterogeneous catalyst. n Proposed method permits to use existing process plants used for obtaining aniline and 14-methylaniline. n The invention purpose is to provide the possibility to produce N-methyl-para-anisidine with purity at least 98% and high output that allows arrangement of highly profitable industry-scale manufacturing process.

摘要:A process for preparing a 1-alkyl-3-secondary or tertiary alkyl-4-cyano-pyrazol-5-yl azo dye or a 1-alkyl-3-aryl-4-cyano-pyrazol-5-yl azo dye comprising: n a) reacting a 3-secondary or tertiary alkyl-4-cyano-5-amino pyrazole or a 3-aryl-4-cyano-5-amino pyrazole with a diazotizing reagent to form a pyrazol-5-yl diazonium salt; n b) allowing said diazonium salt to react with an aromatic coupling component to form a 3-secondary or tertiary alkyl-4-cyano-pyrazol-5-yl azo dye or a 3-aryl-4-cyano-pyrazol-5-yl azo dye; and n c) reacting the product of step b) with an aklylating agent in the presence of a base to form a 1-alkyl-3-secondary or tertiary alkyl-4-cyano-pyrazol-5-yl azo dye or a 1-alkyl-3-aryl-4-cyano-pyrazol-5-yl azo dye.

标 题:Process for the preparation of water-soluble azo dyestuffs by reacting an aromatic amine and a coupling component with alkali metal nitrite or alkyl nitrite in the absence of acid
发明人：LANDLER JOSEF; WORFEL ERHARD
权利人:HOECHST AG
摘要:A new and very advantageous Process had been found for the preparation of azo dyestuffs by diazotation and coupling in which the synthesis is carried out without the hitherto usual addition of an acid, with the proviso that at least one of the diazo and coupling components contains at least one acid group. Besides the saving of reaction material and subsequently of alkali for neutralization of the reaction medium and isolation of the dyestuff, highly concentrated solutions of the dyestuff and salt-free or practically salt-free dyestuffs can be obtained, and waste-water is no longer charged with big amounts of salts.
