摘要
To provide a process for producing, simply and with high reproducibility, a double metal cyanide complex catalyst having an organic ligand, which has a high catalytic activity, a small particle size and a high particle size uniformity.;A process for producing a double metal cyanide complex catalyst having an organic ligand, comprising (a) a step of contacting an aqueous metal halide compound solution and an aqueous transition metal cyanide compound solution in a laminar flow state to obtain a liquid containing a double metal cyanide complex, and (b) a step of mixing the liquid containing a double metal cyanide complex, and an organic ligand, to obtain a dispersion containing a double metal cyanide complex catalyst having an organic ligand.
