N-alkylated aromatic amines are produced by reductively alkylating an aromatic amine with pressurized hydrogen in the presence of a ketone, a noble metal catalyst and a promoter acid having a pKa between 0.3 and 1.5.

Reductive alkylation of substituted anilines

The invention relates to a method for the denitrosation of organic nitrosamines with aliphatic and cycloaliphatic ketones or aliphatic aldehyes in the presence of a strong acid, and optionally an inert organic solvent.

Amino J Acid is reacted with alkali to produce J Acid. The use of a phenolic compound as a fluxing agent for the reaction mixture permits the use of higher temperatures to produce high yields of J Acid in shorter reaction times.

There is provided a process for the preparation of 3,5-disubstituted pyrazoles which involves: A. the reaction of a methyl ketone, such as acetophenone or an appropriate derivative thereof, with an appropriate aldehyde, such as benzaldehyde in the presence of base to form a 1,3-disubstituted .alpha.,.beta.-unsaturated ketone, such as chalcone or a substituted chalcone, B. the acidification of said .alpha.,.beta.-unsaturated ketone, followed by treatment of the acidified reaction mixture with hydrazine to form a disubstituted pyrazoline, and C. the catalytic dehydrogenation of said pyrazoline to yield the desired 3,5-disubstituted pyrazole.

Catalytic dehydrogenation process for the preparation of

A novel process for producing 2-amino-6,8-naphthalenedisulfonic acid (Amino G Acid) and 2-amino-5,7-naphthalenedisulfonic acid (Amino J Acid) which comprises heating 2-amino-1-naphthalenesulfonic acid (Tobias Acid) in 100% sulfuric acid, sulfonating the heated mixture with sulfur trioxide at a temperature in the range of 90.degree.C. to 150.degree.C. and hydrolyzing the sulfonation product.
