Chemistry is the experimental and theoretical study of materials on their properties at both the macroscopic and microscopic levels.In a patent， Application In Synthesis of Titanocenedichloride, Which mentioned a new discovery about 1271-19-8
A […] synthetic method (by machine translation)
The invention discloses a simple, environmentally friendly […] synthetic method, namely N of titanium tetrachloride, N – dimethyl formamide solution is sequentially added in the diethylamine and cyclopentadiene, after mixing of reflux reaction, after the reaction, cooling to room temperature, the pressure and dry solvent, then adding ice water stirring, red precipitate out, the decompression, solid ice washing, to obtain crude […]; […] crude product by N, N – dimethyl formamide is fully dissolved, the decompression, the resulting solid filtrate turns on lathe does the ice – dichloromethane – ethanol mixing the fluid is heavy crystallization, filtering to obtain a red acicular crystal, dried under vacuum to get […]; the method of the invention reduces the reaction time is greatly improves the yield of the reaction; at the same time uses economic and environmental protection of solvent, avoids the use of toxic and harmful solvent, the danger to the environment is relatively small, accord with the green, environment-friendly chemical synthesis concept.
