Manufacturing method of chlorinated isobutyl ketone
I. OVERVIEW
Chlorinated isobutyl ketone is an important raw material for the production of chemicals, which is widely used in the fields of pharmaceuticals, pesticides and spices. In this paper, we will introduce the manufacturing method of chlorinated isobutyl ketone, including raw material preparation, reaction process, post-treatment and other processes.
II. Raw material preparation
The main raw materials for manufacturing chlorinated isobutyl ketone are isobutyl ketone and chlorine gas. In order to ensure the smooth progress of the reaction, it is necessary to carry out strict quality control and pretreatment of raw materials.
1. Isobutyl ketone: the isobutyl ketone with high purity should be selected to avoid the substances containing moisture, impurities and other substances affecting the reaction effect.
2. Chlorine gas: Dry chlorine gas should be selected to avoid containing moisture and other impurities.
3. Reaction process
The manufacturing process of chlorinated isobutyl ketone mainly includes the following steps:
1. Add isobutyl ketone into the reactor and control certain temperature and pressure.
2. Gradually pass chlorine gas to react with isobutyl ketone to produce chlorinated isobutyl ketone.
3. Reaction temperature and time are controlled to avoid excessive chlorination and generation of by-products.
4. At the end of the reaction, the reaction solution is cooled, separated and purified to obtain chlorinated isobutyl ketone with high purity.
4. Post-treatment
To ensure the quality and purity of chlorinated isobutyl ketone, the following post-treatment processes are required:
1. Wash the reaction solution to remove the impurities and by-products.
2. Distill the chlorinated isobutyl ketone to obtain a product with higher purity.
3. Dispose of the residual liquid after distillation to avoid pollution to the environment.
V. Precautions
In the manufacturing process of chlorinated isobutyl ketone, the following matters need to be paid attention to:
1. Strictly control the quality of raw materials and pretreatment to avoid adverse effects on the reaction.
2. Control the reaction temperature and pressure to avoid excessive chlorination and generation of by-products.
3. Carry out sufficient post-treatment of the reaction solution to ensure the quality and purity of the product.
4. Pay attention to safety during operation to avoid the harm of chlorine gas and other harmful substances to the operator.
VI. Summary
The manufacturing method of chlorinated isobutyl ketone includes the processes of raw material preparation, reaction process and post-treatment. In the manufacturing process, the quality of raw materials and reaction conditions need to be strictly controlled to avoid the generation of by-products and to ensure the quality and purity of the product. At the same time, it is also necessary to pay attention to operation safety to avoid harming the operator and the environment.
