Butanal → Trimethylolpropane

Participants

Reaction Conditions

Reaction Steps

231.75 g of distilled water, 175.18 g (1.75 mol) of 30% strength aqueous formaldehyde solution, and 72.28 g (0.70 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 4 hours. According to GC analysis, trimethylolpropane was obtained in a yield of 76.34% of theory.
