MIBK (4-methyl-2-pentanone) is an important organic chemical raw material, which is widely used in the fields of medicine, pesticide, spice and dye. The following will introduce the manufacturing method of MIBK.
I. Raw materials and equipment
1. Raw materials: acetone, formaldehyde, hydrogen.
2. Equipment: reactor, condenser, separator, catalyst loading device, control system and so on.
2. Manufacturing steps
1. Catalyst loading: Load the catalyst into the reactor, the catalyst can be copper-zinc-aluminum catalyst or nickel catalyst.
2. Raw material mixing: Mix acetone and formaldehyde according to a certain proportion, and then pass into the reactor. Hydrogenation: Hydrogen is introduced in the presence of catalyst to produce MIBK and water.
4. Separation of products: After completion of the reaction, the reaction products are cooled and separated to give crude MIBK and water.
5. Refining: The crude MIBK product is refined to give a high purity MIBK product.
3. Precautions
1. Control the reaction temperature and pressure to ensure the smooth progress of the reaction.
2. The catalyst needs to be replaced or regenerated regularly to ensure the catalytic effect.
3. Regular maintenance and repair of the reactor and equipment to ensure the normal operation of the equipment.
4. Safety and environmental protection requirements
1. During the production process, safety operation regulations should be strictly observed to ensure the safety of employees and equipment.
2. Effectively treat the waste water and waste gas produced and discharge them after meeting the national environmental protection requirements.
In short, the manufacture of MIBK needs to strictly observe the safety and environmental protection requirements and control the reaction conditions and operation process to ensure the quality and yield of the product. At the same time, it is also necessary to actively explore new manufacturing processes and technologies to improve production efficiency and reduce costs to create greater economic and social benefits for the enterprise.
