Catalytic reaction coupling of propane dehydrogenation with nitrobenzene hydrogenation over Pt/Al2O3

Catalysis Communications, 2022
Reaction coupling between propane dehydrogenation and nitrobenzene hydrogenation over a commercial Pt/Al2O3 catalyst is presented. The effects of coupling, use of the catalyst, and reaction temperature were studied using a fixed-bed reactor. The coupling

Synthesis and Spectroscopic Properties of New Azo Dyes Derived from 3-Ethylthio-5-cyanomethyl-4-phenyl-1,2,4-triazole

Molecules, 2014
New 1,2,4-triazole colorants were obtained, in high yields, by coupling 3-ethylthio-5-cyanomethyl-4-phenyl-1,2,4-triazole (1) with diazotized aniline derivatives 2, 4 and 6. The azo dyes prepared in this work may exist in three tautomeric forms.
