Industrial production technologies for high-purity tri-n-butylaluminum and tri-n-octylaluminum

Thread Content

1. Technical specifications required for the preparation of high-purity tri-n-butylaluminum: For tri-n-butylaluminum, the content of the main component should be ≥98%; the hydrogenated aluminum content should be ≤0.5%, and the aluminum ethylate content should also be ≤0.5%. The color should be colorless or light brownish-gray, with a transparency of 13.2%； Tetrabutyltin: ≥95%, pale yellow transparent liquid; tin content: 33.5%. 2. The process of preparing tetraoctyltin by reacting industrial tri-n-octylaluminum with tin tetrachloride, as well as the process of producing tri-n-octylaluminum from hydrogen, n-octene, and aluminum powder; the following technical specifications must be met: For tri-n-octylaluminum, the content of the main component should be ≥98%, the aluminum hydride content should be ≤0.5%, and the ethylaluminum content should also be ≤0.5%. It is a colorless or pale brown-gray transparent liquid, with an aluminum content of 13.2% ； Tetraoctyltin: ≥95%, pale yellow transparent liquid, tin content: 20.8%
