Development trends of silver-formaldehyde and iron-molybdenum-formaldehyde
Thread Content
Any unique insights on future trends? It seems that the iron-molybdenum method is developing well at present
Each has its advantages and disadvantages, but overall, the iron-molybdenum method is the direction of development
There is a huge difference between operational economics and region. If the downstream products are designed to tolerate slightly higher acidity and have lower requirements regarding methanol content, such as phenolic resins, polyformaldehyde, POM, polyols, etc., then iron-molybdenum is suitable. If the downstream product is of the urea-formaldehyde type or similar, it has a slightly higher alcohol content and a lower formic acid content; there are also many processes suitable for this
With the current environmental situation, it’s becoming increasingly difficult to operate in the silver industry
