Versuchsvorschrift

41 g of triethylamine are added to a mixture of 1600 ml of methanol, 500 g of 30% strength formaldehyde solution and 328 g of 2-ethylacrolein in the course of 10 minutes, and the solution is then kept at 78° C. for 7 hours. Low-boiling components are distilled off, after which 390 g (67%, based on 2-ethylacrolein) of the title compound of boiling point 95°-100° C./3 mbar are isolated by distillation under reduced pressure.
