| | Triethyl borate Usage And Synthesis |
| Chemical Properties | Triethyl borate is a Colorless liquid; mild odor. Hydrolyzes rapidly depositing boric acid in finely divided crystalline form. | | Uses | Triethyl borate is used as a solvent in resins, paints, varnishes, adhesives and sealant chemicals. It is used as a catalyst of synthetic waxes and resins. It is an active component of flame retardants in the textile industry and in welding fluxes. It is used to prepare m-tolyl-acetic acid ethyl ester by reacting with 1-bromomethyl-3-methyl-benzene and carbon monoxide using as1,5-hexadiene?dium chloride as a catalyst. Further, it is used in pyrotechnics. | | Uses | Antiseptics, disinfectants, antiknock agent.
Triethyl borate is used as a solvent in resins, paints, varnishes, adhesives and sealant chemicals. It is used as a catalyst of synthetic waxes and resins. It is an active component of flame retardants in the textile industry and in welding fluxes. It is used to prepare m-tolyl-acetic acid ethyl ester by reacting with 1-bromomethyl-3-methyl-benzene and carbon monoxide using as 1,5-hexadiene dium chloride as a catalyst. Further, it is used in pyrotechnics.
Triethyl borate may be used as boron source to synthesize lithium borophosphates, alumina borosilicate ceramic nanofibres and boron-doped single wall carbon nanotubes.CVD precursor for boron modified SiO2 in microelectronics Intermediate for organic-modified borosiloxanes.
| | Preparation | Triethyl borate can be prepared by adding anhydrous ethanol with boric acid or boron trioxide. Can be purified via distillation. | | Definition | ChEBI: A member of the class of borate esters obtained by the formal condensation of three equivalents of ethanol with boric acid. | | 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.
