Abstract
Official abstract text for this publication.
There is provided a method for producing a catalyst liquid containing a Group 6 to 11 transition metal catalyst in which the transition metal catalyst can be prevented from being blackened during storage, the method including performing addition of an alkenyl compound and addition of a phosphorus ligand, and then performing addition of a Group 6 to 11 transition metal catalyst
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for producing a catalyst liquid, comprising performing addition of an alkenyl compound and a phosphorus ligand to a solvent, then performing addition of a Group 6 to 11 transition metal catalyst, and then stirring at room temperature, wherein the alkenyl compound, the phosphorus ligand, and the Group 6 to 11 transition metal catalyst are added in that order; the alkenyl compound is 2,7-octadien-1-ol; the phosphorus ligand is triethylamine 3-(diphenylphosphino)benzenesulfonate; the Group 6 to 11 transition metal catalyst is palladium acetate; and the solvent is at least one selected from sulfolane and water. 2. The production method according to claim 1 , wherein the catalyst liquid is a catalyst liquid for a telomerization reaction. 3. The production method according to claim 2 , wherein the telomerization reaction is a telomerization reaction using butadiene or isoprene as a raw material.
