Embodiment

[0061] 1) According to the mass ratio of starch and carrier = 1:100, take 0.05 grams of starch and 4.5-5.0 grams of γ-Al 2 o 3 , after mixing evenly, the saturated water absorption was tested to be 3.8ml;

[0062] 2) According to the mass ratio of starch and carrier = 1:100, take 0.05 grams of starch and 4.5-5.0 grams of γ-Al 2 o 3 , mix evenly, add deionized water to 3.8ml, stir evenly, impregnate at room temperature for 15 hours, put the impregnated sample in a drying oven to control the temperature at 120°C and dry for 6 hours, the process needs to be stirred 2-3 times, and then the dried Take the sample out and put it into the crucible and cover it. Set the muffle furnace roasting temperature program as room temperature → 200°C (2h) → 400°C (2h) → 600°C (2h) → 600°C (6h) → 300°C (2h) → 0°C (1h), finally take it out after cooling and grind it as a modified carrier;

[0063] 3) Preparation of starch modification catalyst:

Abstract

The invention discloses a method for preparing anthraquinone by an anthracene oxidation method using a starch modified catalyst, using γ-Al 2 O 3 As the carrier, Fe and Zr oxides are the active components, and Fe‑γ‑Al is prepared by equal volume impregnation method. 2 O 3 , Zr‑γ‑Al 2 O 3 Single supported catalyst and Fe‑Zr / γ‑Al 2 O 3 Dual-loaded catalyst, modified carrier according to the mass ratio of starch: carrier = 1:100, while using starch modified carrier to prepare a series of modified catalysts. Ultra-high performance liquid chromatography was used to analyze the product, the catalytic performance of the catalyst in the reaction of anthracene oxidation to synthesize anthraquinone was analyzed, and XRD and other means were used to characterize the catalyst.

Description

technical field [0001] The invention belongs to the technical field of chemical industry, and in particular relates to a method for preparing anthraquinone by an anthracene oxidation method using a starch-modified catalyst. Background technique [0002] Anthraquinone (C 14 h 8 o 2 ) is an important fine chemical and chemical intermediate. It is usually used in industrial fields such as the production of anthraquinone dyes, high-concentration hydrogen peroxide, and enhanced kraft paper production processes, and is even widely used in pharmaceutical fields such as medicine and pesticides. Among them, anthraquinone is the parent substance of a large class of dyes and pigments, and occupies a very important position in the field of synthetic dyes. With the diversification and continuous growth of the fine industry, the demand for anthraquinone products in the domestic and international markets has been showing a steady increase. In view of the huge potential market demand o...
