Abstract

The invention relates to an alloy catalyst and a preparation method and application of catalyst. The alloy catalyst is shown as the formula I, namely TM(100-x)-REX. The alloy catalyst can be used for carrying out catalytic oxidation on cyclohexane to directly generate adipic acid, glutaric acid, succinic acid and KA oil in the presence of oxidizing agents such as air, oxygen gas or oxygen-enriched air, and the main product is adipic acid; the appropriate reaction conditions are as follows: the temperature is 130-150 DEG C and the pressure is 1.0-3.0MPa. The alloy catalyst has the characteristics of good activity, long service life, easiness in separation and the like; the metal alloy catalyst is characterized by being used for carrying out catalytic oxidation on cyclohexane to generate adipic acid, glutaric acid and succinic acid in the presence of air by one step, the reaction process is green and has an energy-saving effect, and the greenhouse gas emission can be reduced.

Description

technical field

[0001] The invention belongs to the field of chemical industry, and in particular relates to a catalyst and its preparation method and application. The catalyst can be used in the direct oxidation reaction of cyclohexane to prepare dibasic acid. Background technique

[0002] Dibasic acids such as adipic acid, glutaric acid and succinic acid are important industrial raw materials, mainly used in the production of engineering plastics, polyurethane foam and plasticizers, such as nylon 66 and nylon 66. In addition, the above-mentioned dibasic acids can also be used in the production of high-grade lubricants, food additives, pharmaceutical intermediates, fragrance and flavor control agents, new single crystal materials, plastic foaming agents, coatings, insecticides, adhesives and dyes, etc. very broad.

[0003] The production methods of adipic acid mainly include phenol method, cyclohexane method, cyclohexene method and butadiene method, etc., but the current ...
