| Hazard Information | Back Directory | [Chemical Properties]
Triethyl borate is a Colorless liquid; mild odor. Hydrolyzes rapidly depositing boric acid in finely divided crystalline form. | [Definition]
ChEBI: A member of the class of borate esters obtained by the formal condensation of three equivalents of ethanol with boric acid. | [Preparation]
Triethyl borate can be prepared by adding anhydrous ethanol with boric acid or boron trioxide. Can be purified via distillation. | [Hazard]
Flammable, dangerous fire risk. | [Safety Profile]
Moderately toxic by ingestion. Aneye irritant. A very dangerous fire hazard when exposed toheat or flame. When heated to decomposition it emitsacrid smoke and irritating fumes. | [Purification Methods]
Dry it over sodium, then distil it. Also fractionate it through a gauze packed column. [Charnlet et al. J Chem Soc 2288 1952, as for tributyl borate Johnson & Tompkins Org Synth Coll Vol II 106 1943, Beilstein 1 III 1339, 1 IV 1365.] |
