Butanal → Trimethylolpropane

Participants

Reaction Conditions

Reaction Steps

117.90 g of distilled water, 250.25 g (2.5 mol) of 30% strength aqueous formaldehyde solution, and 77.44 g (0.75 mol) of triethylamine were placed in a 1 liter glass reactor at 25° C. 36.46 g (0.5 mol) of butyr-aldehyde were subsequently metered in over a period of 45 minutes and the reactor temperature was at the same time increased linearly to 70° C. After the metered addition was complete, the mixture was stirred under reflux for another 3 hours. According to GC analysis, trimethylolpropane was obtained in a yield of 82.77% of theory.
