This invention provides a method for manufacturing dibenzylamine. Benzonitrile and a reaction solvent are mixed in a high-pressure reactor, and a hydrogenation reaction is carried out under the action of a ruthenium-iron bimetallic catalyst supported on cerium oxide to obtain a crude product. After cooling and filtering the catalyst, the crude product is purified by distillation to obtain the final dibenzylamine. This method features mild reaction conditions, high atom utilization, and meets the requirements of clean and green production.

This invention relates to the field of livestock breeding technology, and more particularly to an acidic solid environmental conditioner for pig farms, its preparation method, and its application. By mass percentage, its raw materials consist of the following components: 80%-90% natural minerals, 4%-8% natural acidic extracts, 4%-8% natural organic acids, 0.5%-1% photocatalytic nanomaterials, and 1.5%-3.0% natural compound essential oils; and the sum of the mass percentages of each component is 100%. The advantages of this invention are that it contains natural mineral components and natural active extract components, wherein the natural mineral components are mainly calcium-based bentonite and nano-titanium dioxide; the natural active extract components are mainly phenyl lactic acid, citric acid, and plant extracts; it has antibacterial, dehumidifying, and deodorizing effects; it is safe and non-toxic when applied to pig farm environments, does not induce drug resistance, leaves no residue, is low in cost, has stable performance, and is easy to use. It can significantly reduce the number of bacteria in pig houses, reduce ammonia concentration and humidity, and plays an important role in maintaining a good breeding environment and reducing the incidence of disease in pig herds.

The application discloses high-protein pig feed and a preparation method thereof, and particularly relates to the field of high-protein pig feed preparation. Beer yeast cell wall residues and defatted tenebrio molitor sand are subjected to protease enzymolysis, enzyme inactivation, drying and crushing to obtain modified protein cores. Konjac glucomannan is subjected to sodium periodate oxidation, purification and drying to obtain oxidized konjac glucomannan. The modified protein cores are dispersed in a solvent, and a zinc nitrate hexahydrate solution, a 2-methylimidazole solution and a mixed solution of oxidized konjac glucomannan and tannic acid are added dropwise to carry out a reaction to obtain high-protein composite microparticles. The high-protein composite microparticles are uniformly mixed with high-protein basic feed to obtain the high-protein pig feed. The high-protein composite microparticles have a pH-responsive controlled-release shell layer, can provide stomach protection for the modified protein cores, realize targeted release in the intestinal tract, help to improve the protein utilization rate, improve intestinal health, and have good storage stability.
