Problems solved by technology

The traditional preparation method is to use a kettle reaction. The catalyst is Raney nickel powder, and copper-based catalysts are also used, but the reaction pressure is high, usually 2-6MPa; the temperature is also high, usually above 150°C, and there are many side reactions. Inner nickel is easy to spontaneous combustion, not easy to store

Abstract

The invention discloses a loaded catalyst and an application thereof in diisobutyl carbinol preparation. The loaded catalyst is prepared by taking Ni as activated components, taking activated aluminium oxide as carriers and adding a promoter, wherein the promoter is composed of metal Mn, Co and Cu. According to the loaded catalyst and the application thereof in diisobutyl carbinol preparation, diisobutyl ketone serves as raw materials and reacts with the loaded catalyst, and under the conditions that the temperature is set at 100-150 DEG C, the pressure is set at 0.1-1.0 MPa and the airspeed is set at 0.1, diisobutyl carbinol is prepared from 0.1 m<3> of the raw materials through 1 m<3> of the catalysts in 1 h. The conversion rate of the built Ni catalyst is above 90 percent on the conditions of 0.2 Mpa and 100-140 DEG C, and the byproduct quantity is smaller than 1%; the activity of the catalyst is not lowered obviously after the catalyst is operated for 500 hours, and therefore the reaction has an industrialized prospect.

Description

technical field [0001] The invention relates to a supported catalyst, specifically a Ni-loaded catalyst, and the catalyst is applied to the preparation of diisobutyl carbinol. Background technique [0002] Diisobutylmethanol is an important chemical raw material, mainly used in the production of H by anthraquinone 2 o 2 as a solvent for hydroanthraquinone. The traditional preparation method is to use a kettle reaction. The catalyst is Raney nickel powder, and copper-based catalysts are also used, but the reaction pressure is high, usually 2-6MPa; the temperature is also high, usually above 150°C, and there are many side reactions. Inner nickel is prone to spontaneous combustion and is not easy to store. [0003] With H 2 o 2 In order to expand the production capacity, 2-amylanthraquinone must be used as a hydrogenation carrier to increase the unit production capacity. Diisobutyl methanol is currently the most suitable solvent for 2-amylanthraquinone, and the market dema...
