Downstream Industrial Chain of Phosphorus Chemical Industry
Product details
Industrial POCl3 production line using phosphorus trichloride and oxygen oxidation process. Automatic continuous synthesis, distillation and purification for high-purity phosphorus oxychloride liquid.
Product Overview
Our POCl3 production line is a professional fine phosphorus chemical manufacturing system. It adoptsmature PCl3 liquid-phase oxygen oxidation process, using phosphorus trichloride and pure oxygen as core raw materials. Through continuous low-temperature oxidation reaction, rectification purification and sealed packaging, the plant produces high-purity industrial-grade phosphorus oxychloride. The whole line runs fully sealed with stable output and can be perfectly connected with PCl3 and yellow phosphorus production lines.
Core Reaction Principle
Phosphorus oxychloride is directly synthesized by oxidation of phosphorus trichloride with oxygen:
The reaction is stable and easy to control. Precise oxygen proportion effectively avoids by-products, ensuring high-purity finished POCl3.
Production Process Flow
Raw Material Dosing Qualified PCl3 liquid is precisely metered and sent into sealed oxidation reactor.
Continuous Oxygen Oxidation Pure oxygen is injected proportionally for low-temperature oxidation reaction under constant pressure.
Distillation & Purification Crude POCl3 enters rectification tower to remove residual PCl3 and trace impurities.
Condensation & Collection High-purity POCl3 vapor is condensed into transparent liquid and collected.
Sealed Storage & Packaging Finished product is stored in anti-corrosion sealed tanks and packaged for transportation.
Core Equipment Advantages
Stable Oxidation Process – Precise gas-liquid ratio control ensures high product purity and low impurity rate.
Fully Sealed Negative Pressure Operation – No leakage, safe and environmentally friendly continuous production.
Anti-Corrosion Material Configuration – Resistant to strong corrosive media, long service life.
PLC Automatic Control – Stable reaction parameters, less labor, consistent product quality.
POCl3 is a key fine phosphorus chemical intermediate, widely used in pesticide manufacturing, pharmaceutical synthesis, flame retardant production, dye industry and chemical auxiliary processing.
FAQ：
Q1: How to produce phosphorus oxychloride?
POCl3 is produced by oxidizing phosphorus trichloride (PCl3) with pure oxygen, followed by distillation and purification.
Q2: What is POCl3 used for?
It is mainly used as an important chemical intermediate for pesticides, pharmaceuticals and flame retardant materials.
Q3: Is POCl3 production safe?
Our fully sealed negative pressure system and automatic parameter interlock ensure safe and stable production.
