Activation conditions for molecular sieves used for water removal
Thread Content
In my work, I need to use molecular sieves to remove water from solvents, but I am not very clear about the activation conditions for molecular sieves. I would appreciate it if someone with more experience could give me some guidance: at what temperature should the molecular sieves be activated, how long does this process take, and what is the appropriate ratio between molecular sieves and solvents? Thank you, and wish everyone a pleasant workday in advance!
According to the manufacturer’s requirements, we use UOP 4A molecular sieves that do not need to be activated before use; regenerating them 2–3 times is sufficient
400 degrees, activation for one hour – this ensures that the water content in the molecular sieve is less than 1.5%
What device do you use to dry solvents? Thank you!
