Storage method
Storage Precautions[19] Store in a cool, ventilated warehouse. Keep away from fire and heat sources. Keep container tightly sealed. They should be stored separately from oxidants, reducing agents, acids, alkalis, and food chemicals, and avoid mixed storage. Equipped with the appropriate variety and quantity of fire equipment. The storage area should be equipped with emergency release equipment and suitable containment materials.
Synthesis method
Methoxylation reaction between o-nitrochlorobenzene, caustic soda and methanol is carried out to obtain a crude product. The crude product is distilled, washed and dried to obtain the finished product. Raw material consumption quota: o-nitrochlorobenzene 1120kg/t, methanol 270kg/t.
Refining method: Repeated vacuum distillation in the absence of air.
