Contents
Properties
Chemical
Triethyl borate burns in air with a green flame, releasing carbon dioxide, water vapors and boron oxide/boric acid fumes.
Physical
Triethyl borate is a colorless liquid, which slowly hydrolyzes in water and miscible with many organic solvents, like alcohols.
Availability
Triethyl borate is sold by chemical suppliers.
Preparation
Triethyl borate can be prepared by adding anhydrous ethanol with boric acid or boron trioxide. Can be purified via distillation.
Projects
- Make green flame
- Purify boric acid
Handling
Safety
Triethyl borate readily hydrolyzes in water and this makes it irritant to skin, eyes and mucous tissue.
Storage
Triethyl borate should be stored in closed bottles, in a dry medium, such a glovebox or desiccator.
Disposal
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.
