Sodium hypochlorite, phosphine oxide, available chlorine

2017-01-20View Original

Thread Content

In the acetylene gas purification system, what can the sodium hypochlorite solution and the effective chlorine level in the cleaning tower tell us? When the flow rate of acetylene gas increases, the effective chlorine level decreases; conversely, what happens? The question bank states that excessive effective chlorine can lead to the formation of chloroacetylene, which can cause explosions. However, despite searching through many sources, I still couldn’t find any evidence supporting the idea that chloroacetylene can explode Not even in equations? Each time, the effective chlorine content of sodium hypochlorite delivered in tankers ranges from 12 to 15, with a deviation from the alkaline value of around 0.3 to 0.5, which is the general range. Actually, what I want to know is whether the chloride ions in sodium hypochlorite play an oxidizing role? Sodium hypochlorite removes hydrogen sulfide and phosphine. It can still be understood in this way: effective chlorine is directly related to the amount of sodium hypochlorite remaining.
