Hazard InformationBack Directory
[Chemical Properties]

Trimethylolpropane is a Colorless, hygroscopic crystals. Soluble in water and alcohol. Combustible.The three primary hydroxyl groups undergo the normal OH group reactions.
[Chemical Synthesis]

Trimethylolpropane is made by the base-catalyzed aldol addition of butyraldehyde with formaldehyde followed by Cannizzaro reaction of the intermediate 2,2-bis(hydroxymethyl) butanal with additional formaldehyde and at least a stoichiometric quantity of base.
synthesis of trimethylolpropane (TMP)
[Purification Methods]
