Picric acid may be made by gradually adding a mixture of phenol and sulfuric acid at 90—100°C to a nitration acid containing a small excess of nitric acid. The picric acid crystals are separated by centrifugiag, washed, and dried. The wash water is reused to decrease losses owiag to the water solubiUty of the picric acid. A yield of about 225% of the weight of phenol is commonly obtained. [Pg.18]

The nitration of cellulose is unusual in that uniform reaction takes place even though the fibrous structure is retained. This is explained by the fact that nitration is an equilibrium reaction unaffected by fibre structure, the extent of nitration being determined by the strength of the nitrating acid. [Pg.615]

They may require pH adjustment and settling. These effluents should preferably be recycled or reused. Spent catalysts are usually sent for regeneration or disposed of in a secure landfill. Air emissions should be monitored aimually, except for nitrate acid plants, where nitrogen oxides should be monitored continuously. [Pg.67]

Nitric acid in any concentration attacks lead steadily, but mixtures of nitric and sulfuric—nitration acids—are not as active and can be handled in lead. [Pg.86]

Radical and ionic nitrations are often competitive pathways in strong nitrating acid rmxtures. The predominant reaction pathway is determined by the composition of the nitrating medium. Oxides of nitrogen in the nitrating medium add to... [Pg.389]

While concentrated nitric acid passivates steel, the phenomenon is too unreliable to permit cast irons to be used with confidence, even for strong nitric acids. The evidence available in relation to mixed nitrating acids. [Pg.594]

In both stages, turbulent flow of the impinging streams is very desirable. The spent acid of the second stage, upon separation of the TNT, is fortified with aq nitric acid and is reused as the nitrating acid for the first stage... [Pg.238]
