Triethyl borate burns in air with a green flame, releasing carbon dioxide, water vapors and boron oxide/boric acid fumes.
Triethyl borate is a colorless liquid, which slowly hydrolyzes in water and miscible with many organic solvents, like alcohols.
Triethyl borate is sold by chemical suppliers.
- Make green flame
- Purify boric acid
Triethyl borate readily hydrolyzes in water and this makes it irritant to skin, eyes and mucous tissue.
Triethyl borate should be stored in closed bottles, in a dry medium, such a glovebox or desiccator.
Triethyl borate can be safely burned. It will hydrolyze in water to yield ethanol and boric acid, which pose low toxicity to the environment and don't require special disposal.
