Phosphorus trichloride plays an important role in the field of chemical production raw materials, and its upstream and downstream related products are widely used. The following is a detailed description of the upstream and downstream associated products of phosphorus trichloride.

upstream products:

1. Phosphate rock: Phosphate rock is one of the main raw materials of phosphorus trichloride, which is used to produce yellow phosphorus and then prepare phosphorus trichloride.
2. Coke: Coke is used as a reducing agent in the smelting process of phosphate rock and reacts with phosphate in phosphate rock to generate yellow phosphorus.
3. Chlorine: Chlorine reacts with yellow phosphorus to generate phosphorus trichloride, so chlorine is also an important raw material in the production of phosphorus trichloride.

downstream products:

1. phosphorus oxychloride: phosphorus trichloride reacts with oxygen to generate phosphorus oxychloride, which is an important chemical raw material and can be used to produce pesticides, pharmaceutical intermediates, etc.
2. Organic phosphorus compounds: phosphorus trichloride can react with organic compounds such as alcohols and phenols to generate corresponding organic phosphorus compounds, such as phosphate esters, phosphate triesters, etc. These compounds are widely used in plastics, rubber, coatings and other fields.
3. Phosphate: Phosphorus trichloride can react with alkali metal or alkaline earth metal hydroxides to generate corresponding phosphates, such as sodium phosphate, potassium phosphate, etc. These phosphates can be used as food additives, fertilizers, etc.

From the above introduction, it can be seen that phosphorus trichloride has a wide range of upstream and downstream related products in the field of chemical production raw materials, which plays an important role in promoting the development of the chemical industry. At the same time, it should also be noted that in the process of production and use, safety management and environmental protection measures need to be strengthened to ensure product quality and environmental safety.

above is only a brief introduction of some phosphorus trichloride upstream and downstream related products, in fact, phosphorus trichloride is widely used in the chemical field, there are many upstream and downstream related products, specific products need to be determined according to different production processes and market demand.
