The phenol conversion is more than 99% and the yield of aniline is more than 96%. Catalyst stability, no regeneration, but also a diphenylamine production. Therefore, this method is suitable for large-scale continuous production and can produce diphenylamine according to need. But the cost of ...
To convert aniline to benzoic acid, we can follow a series of chemical reactions. Here’s a step-by-step breakdown of the process:Step 1: Diazotization of Aniline 1. Starting Material: Aniline (C6H5NH2) 2. <str
According to the different raw materials, the synthesis methods of diphenylamine can be divided into: aniline-aniline hydrochloride condensation, aniline-phenol condensation, aniline condensation, cyclohexylamine method, cyclohexanone method, phenylhydroxylamine method, etc. There are three main industrialized ...

This process has the characteristics of high conversion rate of benzene and good selectivity. Aniline was synthesized from benzene with 25% ammonia and oxygen at 140~160 ℃ under 1.5MPa, the total selectivity of aniline is 94% (approximately 5% of phenol and 1% of benzene), aniline was ...
aniline is produced in the U.S., several European countries and Japan by the catalytic hydrogenation of nitrobenzene in either the vapor phase or solvent system. This chemical is also produced by reacting phenol with ammonia (HSDB 1989). Production in 1982 amounted to 331,000 tons (HSDB 1989...
to oxidant stress. Pollutant tolerance seems to correlate with the ability to deposit large quantities of pollutant metabolites in the ‘bound’ residue fraction of plant cell walls compared to the vacuole. In this regard, particular attention is paid to the activities of peroxidases, laccases, ...
