Usage

General Description

Ortho-Dichlorobenzene (o-Dichlorobenzene) is a volatile, colorless, non-flammable, liquid organic compound that belongs to the family of aromatic hydrocarbon compounds, with the chemical formula C6H4Cl2. Known for its strong, distinctive smell, it is commonly used as an industrial solvent, degreasant, chemical intermediate, and is found in some insecticides. Exposure to o-Dichlorobenzene can occur through inhalation, skin contact, or ingestion, and may cause harmful health effects such as irritation of the eyes, skin, and throat, dizziness, and liver damage in higher concentrations. It is considered to be potentially carcinogenic by several health organizations.

A method for producing o-dichlorobenzene by one-pot method of o-nitrochlorobenzene as raw material

The present invention relates to a method for producing o-dichlorobenzene by a pot method of producing o-nitrochlorobenzene as raw material. Based on a continuous reactor, the continuous reactor is a reaction device connected to the reaction kettle and the catalyst packing tower, the opening of the reaction kettle is directly connected to the inlet at the bottom of the tower, the reaction kettle is provided with a feeding port and an aeration port, the catalyst packing tower top is provided with a gas inlet outlet, o-nitrochlorobenzene and continuously passed chlorine as raw material, with peroxide and azode complex catalyst as the catalyst, at 225-255 ° C, 0.11- Under the condition of 0.15Mpa, the denitrochlorination reaction was carried out in a continuous reactor to generate o-dichlorobenzene and tail gas nitrate chloride, and o-dichlorobenzene was elicitated from the top outlet of the tower along with the tail gas nitrate chloride, and the liquid o-dichlorobenzene, o-dichlorobenzene and tail gas nitroyl chloride were condensed to a residence time of 5-20min in the catalyst packing column. The high-temperature, short-term synthesis of o-dichlorobenzene, energy consumption is significantly reduced, there are few by-products, no isomers, and the conversion rate is high, up to 95%.
