Methacraldehyde polymerization inhibitor, deep dehydration
Thread Content
Has anyone here experience with the inhibition of acraldehyde or methacraldehyde? Methacraldehyde tends to polymerize during hydrogenation to methallyl alcohol at 80–90°C or during distillation; it is not clear which inhibitor would be effective for preventing this polymerization. Additionally, how is methacraldehyde deeply dehydrated?

Can hydroquinone be used at high temperatures?
Deep dehydration can be achieved using molecular sieves, but polymers affect the lifespan of these molecular sieves.
To what extent can molecular sieves achieve dehydration?
Dehydration using molecular sieves can achieve levels below 100PPM
