Methanol potassium permanganate experiment
Thread Content
The analysis of distilling methanol using potassium permanganate takes a short time, and the result does not meet the standards for premium quality. What substance in methanol distillation is having an impact? How should it be adjusted?
There are many reducing impurities, which reacted with the oxidizing potassium permanganate, resulting in a shorter testing time for potassium permanganate. In operation, it is necessary to ensure the complete removal of the light components from the pre-tower, the timely discharge of the non-condensable gases from the pre-tower, and the control of the cooling temperature of these gases; if necessary, the amount of extraction water should be increased.
The answer to this question is on the forum; give it a search. I need to find some time to sort through the materials from each section as well as the representative typical questions, compile them into a summary post, and make it visible at the top for easy reference. The problem is that I’m not sure if I have the time and energy for this; it’s a huge amount of work.
Check the distillation temperature; some unsaturated compounds have not been distilled out.
It is related to both methanol synthesis and distillation
