Chemical production undertaking

① Raw material processing. In order to make the raw materials meet the state and specifications required for the chemical reaction, different raw materials need to undergo various pretreatments such as purification, concentration, mixing, emulsification or pulverization (for solid raw materials), depending on the specific situation.

② chemical reaction. This is a critical step in production. The pretreated raw materials are reacted under certain temperature, pressure and other conditions to achieve the required reaction conversion rate and yield. The types of reactions are diverse and can be oxidation, reduction, metathesis, sulfonation, isomerization, polymerization, calcination, etc. Through chemical reaction, the target product or its mixture is obtained.

③ product refinement. The mixture resulting from the chemical reaction is separated to remove by-products or impurities to obtain a product that meets compositional specifications. Each of the above steps requires the completion of the required chemical and physical transformations in specific equipment and under certain operating conditions.
