Application
Preparation of Monomeric Ethyl Glyoxylate
Polymeric ethyl glyoxylate toluene solution (30 g) was added to the flame dried flask. Toluene was evaporated completely under vacuum (less than 1 mmHg) at room temperature, and phosphorus pentoxide (ca. 300 mg) was added to the polymeric ethyl glyoxylate. The mixture was distilled to give almost-toluene-free monomeric ethyl glyoxylate as a slightly yellow liquid (150 mmHg, 80 °C). Monomeric ethyl glyoxylate easily polymerizes within 30 min to give viscous liquid. Therefore, distilled ethyl glyoxylate should be used immediately after purification.
