Reaction Steps
The industrial preparation of trimethylolpropane (TMP) starts out from n-butyraldehyde and formaldehyde that are reacted in a two-stage reaction process. In a first reaction step, 2,2-dimethylolbutanal is formed first in a base-catalyzed aldol condensation via the intermediate 2-methylolbutanal. In a subsequent cross Cannizzaro reaction, trimethylol-propane together with formate salts are formed in the presence of stoichiometric amounts of a base.
