Can polyformaldehyde replace aqueous formalin in the synthesis of melamine resin or urea-formaldehyde resin?
Thread Content
Our company currently uses 37% formaldehyde to react with melamine and urea in order to produce polymers. However, after the reaction is complete, a large amount of water must be removed from the reaction products, which requires a significant amount of steam. If solid formaldehyde could be used instead of an aqueous formaldehyde solution to achieve the same results, it would be possible to significantly reduce energy consumption and save costs. I would be very grateful if experts could help find a solution to this issue.
This should work. It just requires a solvent, and ultimately the solvent also has to be removed
Are there relevant **guiding documents as a basis? Currently, project reviews are very sensitive to substances containing the word \"formaldehyde\".
Polymerization also produces water, which needs to be separated as well. The synthesis of triomethylenemethane also requires the generation of water, as well as its separation; energy consumption is incurred either in this process or in that one. Besides, if your resin is a monomer, how can you use trimerization?
