Tripropyl borate Chemical Properties, Uses, Production

Chemical Properties

Colorless liquid

Uses

Tri-n-propyl borate is used as solvents or catalysts for the production of resins, waxes, paints and varnishes, antioxidants, flame retardants. It is also used for petroleum products, tackifiers for silicone elastomers, stabilizers and binders for rubbers or plastics and as cross-linking agents in polymerization processes. They are are used in welding fluxes.

Purification Methods

Dry the ester over sodium and then distil it, preferably in a vacuum. (cf tributyl borate.) [Charnley et al. J Chem Soc 2288 1952, Beilstein 1 IV 1436.]
