| titleOfInvention | The process for refining of paranitrobenzoyl chloride |
| abstract | The invention belongs to fine chemistry industry separation technology field, and in particular to a kind of process for refining of paranitrobenzoyl chloride.The process for refining of paranitrobenzoyl chloride of the present invention, synthesize paranitrobenzoyl chloride mainly for thionyl chloride method, it comprises the concrete steps that and is first reacted paranitrobenzoic acid and excess thionyl chloride, after completion of the reaction, again through air-distillation, vacuum distillation removal thionyl chloride, meta-xylene and paraxylene mass ratio 1 are added:1 organic solvent, it is last sliced to obtain sheet paranitrobenzoyl chloride product by vacuum distillation by solvent and the light component Impurity removal of residual.The technique avoids traditional long-time high vacuum high temperature rectifying purification process, and production efficiency is substantially improved, and product quality stabilization, and high income, energy consumption is low. |
