|what is ?)(|
It melts at −85 °C and boils at 118 °C. It is flammable, with flash point at 11 °C.
It burns with a green flame and solutions of it in ethanol are therefore used in special effects and pyrotechnics.
- B(OH)3 + 3 C2H5OH ⇌ (C2H5O)3B + 3 H2O
In order to increase the rate of forward reaction, the formed water must be removed from reaction media by either azeotropic distillation or adsorption. It is used as a solvent and/or catalyst in preparation of synthetic waxes, resins, paints, and varnishes. It is used as a component of some flame retardants in textile industry and of some welding fluxes.
