MIBK (4-methyl-2-pentanone) is an important organic chemical raw material, which is widely used in medicine, pesticide, spice, dye and other fields. A manufacturing method of the MIBK will be described below.

1. raw materials and equipment

1. raw materials: acetone, formaldehyde, hydrogen.
2. Equipment: reactor, condenser, separator, catalyst loading device, control system, etc.

2. Production Steps

1. Catalyst Loading: A catalyst is loaded into a reactor, and a copper-zinc-aluminum-based catalyst or a nickel-based catalyst can be used as the catalyst.
2. mixing of raw materials: acetone and formaldehyde are mixed according to a certain proportion, and then passed into the reactor.
3. Hydrogenation reaction: under the action of a catalyst, hydrogen is introduced for hydrogenation reaction to generate MIBK and water.
4. Product isolation: After completion of the reaction, the reaction product was cooled and isolated to obtain crude MIBK and water.
5. Refining: MIBK crude product is refined to obtain 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. Regularly maintain and maintain the reactor and equipment to ensure the normal operation of the equipment.

4. safety and environmental protection requirements

1. In the production process, strictly abide by the safety operation procedures to ensure the safety of employees and equipment.
2. Efficiently treat the waste water and waste gas, and discharge them after meeting the national environmental protection requirements.

In short, the manufacture of MIBK needs to strictly comply with safety and environmental protection requirements, and control the reaction conditions and operating processes to ensure product quality and yield. At the same time, it is also necessary to actively explore new manufacturing processes and technologies to improve production efficiency and reduce costs, and create greater economic and social benefits for enterprises.
