Process for the preparation of a precipitate and a catalyst |
| abstract |
A molybdenum-based precipitate is prepared according to a method which comprises a first step of forming a raw precipitate by adjusting pH to 6.5 or less in the presence of an alkali metal compound, and a second step of dissolving the raw precipitate in aqueous ammonia and forming a precipitate by pH- Including setting to 6.5 or less. Then, the resulting molybdenum-based precipitate is washed with an acidic aqueous solution having a pH of 6.5 or less and containing not less than 0.01 mol / ℓ of ammonium residue. Thus, a change in the average particle diameter can be suppressed and good workability can be achieved, so that a molybdenum-based precipitate having a high purity and a desired average particle diameter can be obtained. |
