In homogeneous catalysis, the catalyst is in the same phase as the reactant. The number of collisions between reactants and catalyst is at a maximum.In a patent, 6974-97-6, name is 4,7-Dimethyl-1H-indene, introducing its new discovery. Application In Synthesis of 4,7-Dimethyl-1H-indene
Bridge unites yinyin wu the zirconium, Louis composition and preparation method and application in the oligomerization of propylene (by machine translation)
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)
The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 6974-97-6 is helpful to your research. Application In Synthesis of 4,7-Dimethyl-1H-indene
