Manufacturing method
of chlorinated paraffin
Chlorinated paraffin is an important raw material for chemical production, which is widely used in plastics, rubber, coatings, lubricants and other fields. This article will introduce the manufacturing method of chlorinated paraffin, including raw material preparation, chlorination reaction, post-treatment and other steps.

1. raw material preparation

chlorinated paraffin raw materials are mainly paraffin and chlorine. Paraffin wax should be selected with higher carbon content to ensure the thermal stability and chemical stability of chlorinated paraffin. The chlorine gas shall be dry industrial chlorine gas of high purity.

2. chlorination reaction

chlorination reaction is a key step in the manufacture of chlorinated paraffins, which is generally carried out in a stirred tank. The specific steps are as follows:

1. The paraffin wax is heated to melt, the catalyst is added, and the mixture is stirred evenly.
2. Chlorine gas is introduced, reaction temperature and pressure are controlled, and chlorination reaction is carried out. The chlorination reaction is an exothermic reaction, and the reaction heat should be removed in time to keep the reaction temperature stable.
3. After completion of the chlorination reaction, the chlorine gas was stopped and the reaction solution was cooled to room temperature.

3. post-treatment

After the chlorination reaction is completed, post-treatment is required to obtain qualified chlorinated paraffin products. The specific steps are as follows:

1. washing the reaction solution with lye to remove acidic substances therein.
2. The reaction solution after alkali washing is washed with water to be neutral.
3. Separate by layers to obtain crude chlorinated paraffin.
4. Distillation of chlorinated paraffin crude products to separate chlorinated paraffin products with different boiling points.

4. precautions

1. chlorination reaction process should be strictly controlled temperature and pressure, to prevent the reaction is too violent lead to safety accidents.
2. The selection and use of the catalyst should be reasonable to ensure the progress of the chlorination reaction and the quality of the product.
3. The post-treatment process should ensure that the washing is sufficient to remove impurities in the product.

In short, the manufacturing method of chlorinated paraffin includes the steps of raw material preparation, chlorination reaction and post-treatment. It is necessary to strictly control the process parameters and operation process of each step to ensure product quality and production safety.
