Solid base carrier dilute metal element catalyst and preparation method

Abstract

The invention discloses a solid alkali carrier rare metal element catalyst which is sintered and synthesized from the following components in parts by weight: 15-25 parts of calcium chloride, 15-25 parts of magnesium chloride, 3-5 parts of nano strontium titanate, 50-100 parts of 25% ammonia water, 30-50 parts of aluminium chloride, 0.5-1.5 parts of nano zinc powder, 0.2-0.4 part of nano ruthenium powder, 5-10 parts of potassium hydroxide, 0.5-1.5 parts of magnesium silicide, 100 parts of 4% ammonium chloroplatinate solution, 3-5 parts of a polytetrafluoroethylene adhesive and 10-20 parts of absolute ethyl alcohol. The solid alkali carrier rare metal element catalyst is applied to the preparation of a wrapping type 2,4-counter bromine benzyl benzophenone antioxidant; a reacted product is easy to purify and treat and cannot corrode equipment; the stability of the wrapping type 2,4-counter bromine benzyl benzophenone antioxidant is improved due to a shielding effect of two benzene rings; when being used as an antioxidant for producing stone paper, the wrapping type 2,4-counter bromine benzyl benzophenone antioxidant is obvious in effect.

Description

technical field [0001] The invention relates to the preparation technology and application of a solid base catalyst. Background technique [0002] Science and technology have entered a new era, and new materials with high-tech added value are constantly coming out. The synthesis of new materials requires new technologies and new processes. The application of catalysts has become one of the core technologies of today's science. Solid alkali is a new type of catalyst. , because of its high activity, high selectivity, mild chemical reaction conditions, easy separation of the reaction system, no corrosion of equipment, environmental friendliness, and reusable advantages, it has been paid more and more attention, especially in fine chemical synthesis and polymer synthesis. Many chemical synthesis reactions with harsh reaction conditions can be carried out, and the synthesis reaction process is continuous, which reduces energy consumption and environmental pollution. In recent yea...

Problems solved by technology

However, due to the complex preparation process of antioxidants, serious corrosion of equipment, and environmental pollution in the process of product post-processing, new technologies are needed to improve the deficiencies of existing technologies.

At the same time, the stability of antioxidants needs to be further improved in practical applications, especially in the production of stone paper, which will cause yellowing after a long time. The most important thing to solve is: there is compatibility with the raw materials for stone paper production The problem
