Abstract

The invention relates to a catalyst for synthesizing methyl isobutyl ketone and diisobutyl ketone from acetone, a preparation method and application thereof in the field of catalysts. The catalyst for synthesizing methyl isobutyl ketone and diisobutyl ketone from acetone is measured as 100 parts by the overall weight of the catalyst, and includes the following components: a, 0.5 to 10 parts of at least One; b, 0.5-10 parts of at least one selected from cobalt or cobalt oxides; c, 80-99 parts selected from bismuth-modified basic calcium phosphate. The preparation process of the catalyst of the present invention is relatively simple, easy to control, and the active components should not be lost; the catalyst of the present invention can not only produce methyl isobutyl ketone, but also diisobutyl ketone, and the industrial production device has better adaptability to the market. Strong, the cost of the bimetallic catalyst of the present invention is significantly lower than that of the existing palladium catalyst, and has better economic benefits.

Description

technical field [0001] The invention relates to the field of catalysts, in particular to a catalyst for synthesizing methyl isobutyl ketone and diisobutyl ketone from acetone, a preparation method and application thereof. Background technique [0002] Methyl isobutyl ketone, also known as 4-methyl-2-pentanone (abbreviated as MIBK in English), is an important solvent and chemical intermediate. It has attracted much attention because of its excellent performance. The color is transparent, the boiling point belongs to the middle boiling point, the solubility is very strong, and it can be miscible with many organic solvents such as alcohol, benzene, ether, etc. It can be used as paint, ethyl cellulose, nitrocellulose, audio and video tapes, paraffin, various natural or synthetic Raw materials for resin solvents, dewaxing agents, rare earth metal extractants, polymerization initiators, surfactants, medicines, pesticide extractants, and rubber antioxidants are currently relatively...
