What is the reason why the vaporization pressure of liquid chlorine in fine chemical reactions at atmospheric pressure is generally maintained at around 0.3 MPa?

The reason why the pressure remains at around 0.3 MPa after liquid chlorine is vaporized is likely that at this pressure, liquid chlorine can be effectively vaporized, which also facilitates control and utilization during subsequent reaction processes. Too high or too low pressure can affect the efficiency and safety of the reaction. Ensuring that the pressure remains stable at 0.3 MPa can be achieved through the following methods: 1. Using a pressure control valve: automatically or manually adjusting the pressure of liquid chlorine entering the vaporizer to maintain a stable output gas pressure. 2. Use pressure sensors and control systems: Monitor the pressure of chlorine gas after vaporization in real time, and adjust it through a feedback system to maintain a constant pressure. 3. Control the flow rate of liquid chlorine: Ensure a constant flow rate of liquid chlorine supplied to the vaporizer, in order to avoid pressure fluctuations caused by changes in flow rate. 4. Maintain a stable temperature: The temperature of the vaporizer affects both the rate of vaporization of liquid chlorine and the gas pressure; therefore, it is necessary to keep the vaporizer’s temperature stable. .
