Hi Everybody!
Could you please tell me someone, what is your experience with drying of solid phase after reaction work-up. It means, filtering and thoroughly washing with more organic solvents, and then drying in vacou.
My question is, how long does it take minimally to dry my Solid Phase (cross linked polystyrene with 1% divinyl benzene- derivatized Wang resin, 100-200 mesh), till constant weight at 40°C in vacuo. My last solvent for washing was dichloromethane. It is a long time for me to wait entire night to dry it.
Thank you in advance!
Peter
