90:10 PVOH Clay Microsphere Preparations*Reaction should be carried out using a reflux condenser and a thermostatic water bath of 55°C.
* 1,2-dichloroethane * acetone * hot water * cold water * methanol
* The following procedure was adapted from the article Poly(vinyl alcohol) microspheres with pH- and thermosensitive properties as temperature-controlled drug delivery [1]
Important 1,2 Dichloroethane and Glutaraldehyde Safety
Clay Exchanged Solutions & Vacuum Filtration ProceduresThe clays being filtered are the clays that were prepared on 2/1/13 Setup of a vacuum filtration system: * Clean 250mL Erlenmeyer Filter Flask * Large Buchner Funnel * Whatman #42 Filter Paper * Long Secure Rubber Hose
