Applications
Trimethylolpropane, containing three primary hydroxyl groups in a quaternary mole structure, is a white crystalline solid or clear liquid in molten form at high temperature; melting at 57 C; soluble in water, alcohol, glycerin; insoluble in hydrocarbon solvents. It is prepared by the hydrogenation reaction of aldehyde ( n-butyraldehyde and formaldehyde). It is used as an important raw material in manufacturing polyesters, alkyd and urethane resins. It improves heat resistance, color stability, balance between toughness and flexibility. It is also used in lubricating oils and plasticizers as well as in radiation curing monomers or oligomers.
