三聚氯氰

1.1. The saturated salt water is electrolyzed. Except for sodium hydroxide, the cathode produces hydrogen and the anode produces chlorine.


The equation is as follows: 2NaCl + 2H2O → 2NaOH + Cl2 ↑ + H2 ↑


2. Pass hydrogen gas and chlorine gas to a quartz burner in the reactor to ignite and burn, generating hydrogen chloride gas, and emitting a lot of heat.


H2 + Cl2 → 2HCl


3.The hydrogen chloride gas is absorbed into water and becomes hydrochloric acid after cooling.
