Triethylantimony(III) - Reference Information
| Introduction | triethyl antimony is colorless liquid, long-standing to produce white precipitate, miscible with ethanol and ether, insoluble in water, Alkane metal organic compounds, mainly used in organic synthesis. |
| Application | high purity triethyl antimony provides antimony source for semiconductor materials such as AlSb, GaSb, InSb, etc, metal Organic Chemical Vapor Deposition (MOCVD), Chemical beam epitaxy (CBE) process in the growth of one of the most important source of optoelectronic materials. |
| Use | triethyl antimony is mainly used as a catalyst for organic synthesis. |
| preparation | preparation of triethyl antimony solution: the format reagent was cooled to -25 °c under the protection of nitrogen, take 63.9 ml of diethyl ether to dissolve 0.28g (mol) of antimony trichloride, add antimony trichloride diethyl ether solution Dropwise to the format reagent. After the dropwise addition is completed, raise the temperature to -10 ℃ and stir for 1H, the temperature was further increased to 25 °c and stirred for 1H to produce a triethyl antimony solution. Purification of triethyl antimony: under the protection of nitrogen, the triethyl antimony solution is distilled out of ether at atmospheric pressure, the distillation residue is distilled at reduced pressure and elevated in temperature, and the distilled fraction is a mixed solution of ether and triethyl antimony; the mixed solution was added to another three-necked flask, and the remaining ether was distilled off at atmospheric pressure. The remaining residue in the three-necked flask was continued to be distilled under reduced pressure, and the crude triethyl antimony was distilled off with a purity of 96%, the crude product yield is 61%; The obtained crude triethyl antimony is subjected to vacuum distillation, and the triethyl antimony is easy to decompose due to too high temperature, so the distillation temperature should be controlled not to exceed 80 ℃, triethyl antimony was obtained with a purity of 99.9995%. |
