Chemical process:
1, raw material processing
In order to make the raw materials reach the state and specifications required for chemical reaction, different raw materials need to be purified, concentrated, mixed, emulsified or crushed (for solid raw materials) according to specific conditions.
2. Chemical reaction
This is a key step in production. The pretreated raw materials react under certain conditions, such as temperature and pressure, to achieve the required reaction conversion and yield.
There are many types of reactions, such as oxidation, reduction, metathesis, sulfonation, isomerization, polymerization, roasting and so on. Through chemical reaction, the target product or its mixture is obtained.
3. Refinement of products
Separating the mixture obtained by chemical reaction, removing by-products or impurities, and obtaining the products meeting the composition specifications. Each of the above steps needs to complete the required chemical and physical transformation under specific equipment and specific operating conditions.
