At the same time, 6O% p -nitrophenol is collected in the upper part of the reactor and the pump is pumped through the upper descent into the crystallizer.

The bottom layer, which is a resinous mass containing 40% of the remaining p-nitrophenol, is pumped through the bottom fitting into the container and taken out to the store.

Wastes from the production of P-nitrofenetol Polyvinyl chloride

As dinalkyl phthalate, the composition contains dibutyl or dioctyl or didecyl phthalate.

And-Nitrofenetol is obtained by saponification of P-nitrochlorobenzene with caustic soda in ethanol. In addition, p-nitrophenol is formed as a by-product.

The regeneration of p-nitrophenol is last decomposed with sulfuric acid.
