Why does arginol sulfuric acid wash turn pink/how to deal with it

2008-01-01View Original

Thread Content

Our methanol plant has been running for one year and three months. It may be that the negative reaction of synthesis has increased. What is the reason why the finished product of methanol and sulfuric acid has recently turned pink after washing with sulfuric acid? How to deal with it? Can someone give me some advice?

Is this the case every time? Is the colorimetric tube used correctly?
