SPONGE COBALT, A-8B46 - Introduction
Copper catalyst is a common catalyst with the following properties:
1. Chemical properties: Copper catalysts usually exist in the form of ions in catalytic reactions and can participate in redox reactions. Copper has a variety of oxidation states and can accept or donate electrons, so it can promote oxidation, reduction, hydrogenation, dehydrogenation and other reactions.
2. Physical properties: Copper is a metal with good electrical and thermal conductivity, as well as certain corrosion resistance.
Copper catalysts are widely used in many chemical reactions, including:
1. acetylene synthesis: copper catalyst can promote the addition reaction of acetylene and hydrogen to generate ethylene.
2. dehydrogenation reaction: copper catalyst plays the role of catalyst in dehydrogenation reaction, and has important applications in ammonia synthesis, methanol synthesis and petrochemical industry.
3. organic chemical synthesis: copper catalyst plays an important role in organic chemical synthesis, which can catalyze cyclization reaction, coupling reaction and oxidation reaction.
The preparation method of copper catalyst includes:
1. Direct reduction method: Copper particles are obtained by heating and reducing a copper oxide together with a reducing agent.
2. co-precipitation method: copper salt and alkaline precipitant are added into the reaction solution together to precipitate the copper catalyst.
3. Chemical precipitation method: a precipitate is generated through a chemical reaction, and then the precipitate is separated and washed to obtain a copper catalyst.
Safety information for copper catalysts is as follows:
1. The copper catalyst is easily oxidized in the air to produce copper oxide, so it needs to be stored in a sealed container to avoid oxidation.
2. When in contact with strong acids, copper can produce toxic copper salts, causing irritation and corrosion.
3. Copper catalysts are toxic to the environment and need to follow relevant environmental protection regulations and operating specifications.
4. the use of copper catalyst should pay attention to personal protection, avoid direct contact with the skin and inhalation of its particles.
