Market price:The products of this project are mainly used for pesticides and pharmaceutical intermediates. The market pull point will be mainly in the downstream water treatment agent, pesticide glyphosate and phosphate ester flame retardant.
Route of Synthesis:The project uses yellow phosphorus and chlorine as raw materials, and under certain temperature and pressure conditions, yellow phosphorus and chlorine gas are chlorinated to obtain phosphorus trichloride. This reaction is an exothermic reaction.
Wastes:A small amount of waste water, waste gas and waste residue.
The project uses yellow phosphorus and chlorine as raw materials, and under certain temperature and pressure conditions, yellow phosphorus and chlorine gas are chlorinated to obtain phosphorus trichloride. This reaction is an exothermic reaction.
In the phosphating pool, yellow phosphorus is melted into liquid yellow phosphorus after heating, and is input into the yellow phosphorus metering tank through the submerged pump, and is quantitatively added to the chlorination reactor according to the process requirements. After entering the vaporizer and the buffer tank at the required flow rate, the liquid chlorine enters the reaction tank and reacts with phosphorus, and the generated vapor enters the condenser after passing through the phosphorus washing tower, thereby obtaining a phosphorus trichloride product. The HC1 produced during the production process is absorbed to form hydrochloric acid.
