Diechlorophenol Manufacturing :
Diechlorophenol Manufacturing :
2-4- Diechlorophenol is a white, low melting point solid, having a boiling point 210 digri and melting point 45 digri C. It has a flash point 237 digri F . It is highly combustible . It is soluble in water, alcohol and carbon tetra chloride.
At present eight big company are engaged in manufacturing this product, beside few small scale units, So there is good scope to manufacturing this product in small scale sector. It is mainly used in organic synthesis. Most important use of this chemical is in the manufacturing of 2-4-D ( 2-4-dichlorophenoxy acetic acid ) and its derivatives.
Requirement Raw Material :(Basic 500 kgs. per day)
Phenol 1250 kgs.
Colorine 400 kgs.
Manufacturing Process :
It is prepared by continued chlorination of phenol, with gradual elevation of the temperature above the setting point of the intermediate cholophenol unites pentachlorination has been effected.
The chlorination is carried out in a steam jacket glass lined steel reaction equipped with an agitator and condenser. Phenol is charged into the reactor from the charging aperture on the top of the reactor and chlorine gas is bubbled through molten phenol. Chlorine gas can be controlled from the bottom of the reactor., and bubbling continues until weight of reaction mixture increases by 36 : 50 for every gram of phenol added. The time required for chlorination is about 4-5 hours. The product is then distilled in a fractionation columm. The fraction boiling between 210-215 digri C is collected. The fraction readily crystallizer upon cooling. Finally the product is packed in drums and to different consumers.
Equipment & Machinery:
1. Still reactor with agitator and motor. 1 no.
2. Condenser 1 no.
3. Distillation tank 1 no.
4. Boiler. 1 no.
5. Liquid chlorine storage tank. 1 no
6. Mini boiler 100 kgs/ hour at a pressure of 150 psi. 1no.
7. Miscellaneous tools and equipments.
