| titleOfInvention | Process for preparing a catalyst |
| abstract | Process for preparing a catalyst represented by the formula (1) below: wherein in formula (1) R 1 , R 2 , R 3 and R 4 each independently represent a hydrocarbyl group having from 1 to 20 carbon atoms and optionally at least one heteroatom; R 1 and R 2 are each bonded to a silicon atom through a C-Si bond, an O-Si bond, a Si-Si bond or an N-Si bond; R 3 is bonded to a nitrogen atom through a CN bond, an ON bond, a Si-N bond or a NN bond; R 4 is bonded to a metal atom M through a CM bond; R 5 and R 6 each independently represent an organic substituent having from 1 to 20 carbon atoms and optionally at least one heteroatom, or an inorganic substituent; m and n are each independently an integer from 0 to 4; when a plurality of R 5 and a plurality of R 6 are present, the plurality of R 5 and the plurality of R 6 are each optionally a different group; when two groups of the plurality of R 5 or two groups of the plurality of R 6 are attached to an aromatic ring at respective positions adjacent to each other, the two groups are optionally linked to each other to form a ring; and M is Ti, Zr or Hf, the method comprising: a step (I) in which a represented by the formula below (1a) represented ligand: wherein in the formula (1a) R 1 , R 2 , R 3 , R 5 , R 6 , m and n are as defined above, can react with an organolithium compound represented by the formula (1b) below: LiR 7 (1b) wherein in the formula (1b) R 7 represents a hydrocarbon group having from 1 to 20 carbon atoms and optionally at least one heteroatom and is bonded to a lithium atom via a C-Li bond; a step (II) in which a product obtained from the step (I) is mixed with one or more selected from the group consisting of a compound represented by the formula (1c) below, a compound represented by the formula (1d) below and a compound represented by the formula (1e) below: (R 4 ) p MgX( 2-p ) (1c) (R 4 ) q ZnX( 2-q ) (1d) (R 4 ) r AlX( 3-r ) (1e) wherein in formulas (1c), (1d) and (1e) R 4 is as defined above; X is a halogen atom; p is 1 or 2; q is 1 or 2; and r is an integer from 1 to 3; and a step (III) in which a product obtained from the step (II) is allowed to react with a compound represented by the formula (1f) below in an amount of 1 molar equivalent or more in terms of the ligand: MR 8 4 (1f) wherein in formula (1f) M is as defined above; R 8 represents a halogen atom or a group represented by -OR 9 ; R 9 represents a hydrocarbyl group containing from 1 to 20 carbon atoms and optionally containing at least one heteroatom; and R 9 is linked to an oxygen atom via a CO bond, wherein in step (I) the amount of organolithium compound used is 2.0 molar equivalents or more relative to the ligand when R 4 and R 7 are the same, and in the step (I), the amount of the organolithium compound used is 1.8 molar equivalents or more and 2.2 molar equivalents or is less with respect to the ligand when R 4 and R 7 are not the same, and, in the step (II), a compound selected from the group consisting of the compound represented by the formula (1c), the compound represented by the formula (1d) and the compound represented by the formula (1e) is used in such an amount becomes that the number of moles of the R 4 group in each of these compounds is greater than that of the ligand by 2 times or more. |
