Open Data Verified Data

with p-cresol as raw material, nitric acid, sulfuric acid mixed acid with a certain concentration for nitration, reaction completion, separation of waste acid, after washing and distillation with sulfide alkali reduction, and finally after acid precipitation, crystallization, drying to obtain the finished product.

The hydroreduction method is the same as the 1 method, but is carried out in the presence of a catalyst. Hydrogen reduction was used instead of the alkali sulfide reduction.
