Producing methanol
Thread Content
I would like to ask what by-products are generated during the industrial production of methanol?
Do you mean the methanol synthesis process? Due to limitations in catalyst selectivity, as well as the effects of synthesis conditions such as pressure, temperature, and syngas composition, numerous trace organic impurities are generated alongside methanol; these include aldehydes, ketones, ethers, acids, esters, alkanes, amines, and iron carbonyl.

Then methanol sold from factories should contain propylene as well; how much is that usually?
The propylene content is generally around 5PPM
You’re a product, right? It contains fusel oils and fusel alcohols.
