Trimethyl borate, or boron trimethoxide, has formula B(OCH3)3. It is a clear liquid. It melts at −34 °C and boils at 68-69 °C. It decomposes in contact with water. It is flammable and burns with a green flame.
It is primarily used as a precursor to boronic esters and boronic acids for Suzuki couplings. Other uses include :
- Anti-oxidant in Brazing and Solder Flux
- Wood preservative
- Catalyst of olefin polymerisation
- raw material in the production of borophosphosilicate glass film by chemical vapor deposition
- raw material in the production of specialty glasses using sol-gel technology
- solvent or catalyst for resins, waxes, paints, and varnishes
- component of some flame retardants in textile industry
- component of some welding fluxes
- in green fire compositions for special effects (as a solution of boric acid in methanol, where it forms in small amounts)[1]
