Trimethylolpropane Usage And Synthesis

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.
Uses	Conditioning agent, manufacture of varnishes, alkyd resins, synthetic drying oils, urethane foams and coatings, silicone lubricant oils, lactone plasticizers, textile finishes, surfactants, epoxidation products.
Uses	Large quantities of trimethylolpropane and its ethoxylated derivatives are used as precursors for urethanes and polyester resins. Another important field of application is in medium-oil and short-oil alkyd resins (→Alkyd Resins). The resulting lacquers are characterized by excellent resistance to alkali, detergents, and water, combined with outstanding impact resistance and flexibility, as well as excellent clearness and clearness retention. Reaction products with fatty acids (C5 -C10) are components of synthetic lubricants. A strongly growing market will be the use of these blended polyol esters in chlorine-free, purely fluorocarbon based refrigerant systems. Powder and high-solids coatings represent a strong potential market for TMP, because it contributes to low viscosity. TMP acrylates are used as reactive diluents in UV-cured systems for inks and coatings, and TMP allyl ethers in unsaturated polyesters.
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.
Purification Methods	Crystallise it from acetone and ether and it distils at high vacuum. [Beilstein 1 III 2349.]
