Chemistry is the experimental and theoretical study of materials on their properties at both the macroscopic and microscopic levels.In a patent， Quality Control of: 2-Methyl-1H-indene, Which mentioned a new discovery about 2177-47-1
The invention discloses an inferior ethyl bridge – wuwu zirconium indene, Louis compound and its preparation method and application in the oligomerization of propylene. The invention of the ethylenedioxy-based hydrosilane – wuwu zirconium, Louis composition can be through the ethylenedioxy – fluorenylmethylchloroformate ligand compound hydrosilane-first with alkyl alkali metal in the organic medium reaction, then adding ZrCl4 Or HfCl4 Obtained by the method. The invention of the linen – wuwu zirconiumethyl bridge indene, Louis compound is a high-efficient catalyst, under a comparatively mild condition, used for catalytic oligomerization of propylene, with high catalytic activity, and of the untreated alkyl the alumina alkane helps can be high under the catalysis of the selectively containing the allyl group of acrylic oligomer; at the same time can be controlled by polymerization reaction conditions for the realization of aligned polymer molecular weight control, and has very high industrial application value. Its structure has the following general formula: (by machine translation)
I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 2177-47-1, help many people in the next few years.Quality Control of: 2-Methyl-1H-indene
