3.2. Reaction Procedure for the Synthesis of Glycerol Monoethers

The appropriate amount of alcohol (15:1 with respect to glycidol), the catalyst (5, 10 or 20% mol with respect to glycidol) and diglyme as internal standard (15% w/w with respect to glycidol) were placed into a round bottomed flask. The reaction was stirred and heated at the desired temperature (65 or 25 °C) under argon. Then, glycidol (4.35 mmol) was added dropwise for 15 min. The reaction was monitored at different times by extracting samples that were filtered and diluted with methanol prior to injection in GC. After total consumption of glycidol, the heterogeneous catalysts were just filtered off. Conversions and yields were determined by GC.

All the alcohols were dried and distilled over calcium hydride prior to use.
