Description

CH3CHCH2O [75-56-9] FW 58.08 
1,2-epoxypropane. Must use under hood, and with all caution. Extremely low vapor pressure. "Since epoxy resins are soluble in ethanol and acetone, dehydration is commonly carried out with one of these solvents. Because epoxy resins are more readily soluble in propylene oxide. This solvent is frequently used immediately prior to infiltration with the resin. Most resins are not readily miscible with ethanol". Propylene Oxide does not separate from the epoxy resin during curing, thus small amounts left in the resin do no harm.

Luft introduced Propylene Oxide into epoxy mixtures with his landmark paper and helped bring about improved embedding cures, better ultrastructural research results with blocks that would more reliably section and give better performance under the EM beam by reducing viscosity and increasing penetration.
