P-Nitro chloro benzene - Preparation Method
Open Data Verified Data
after nitric acid and sulfuric acid were mixed into mixed acid, nitration reaction was carried out with chlorobenzene to produce nitrochlorobenzene (para 65%, Ortho 34%, Meta 1%), and then nitrochlorobenzene and waste acid were separated. After separation, the nitrochlorobenzene was washed with water and neutralized to obtain neutral nitrochlorobenzene, which was then dried and crystallized. The product P-nitrochlorobenzene was separated, and the co-dissolved oil was subjected to rectification, de-coking and crystallization to obtain the product O-nitrochlorobenzene.

P-Nitro chloro benzene - Safety
Open Data Verified Data
- This product is highly toxic. Absorption through the skin or inhalation of its vapor can cause poisoning, especially when used together with ethanol, due to the formation of methemoglobin, can cause acute poisoning death. Alcohol can accelerate the central nervous and blood poisoning, the formation of allergies. Production Workshop should have good ventilation equipment, to be closed, to prevent running, run, drip, leakage. Operators should wear protective gear.
- sealed in iron drum, 200kg or 250kg net weight per drum. Store in a cool, ventilated place. During the storage and transportation, it shall be protected from fire, sun and moisture. According to the provisions of the storage and transportation of toxic chemicals.
