1, according to the required purity and chemical characteristics, select the appropriate raw material as the base material of the active diluent.

2, the selected raw materials through the appropriate chemical reaction to synthesize the active diluent.

3, the use of physical or chemical methods to remove impurities generated during the synthesis process, such as volatiles, solvent residues, etc.

4, the use of appropriate technology, such as distillation, crystallization, washing and other methods to refine the active diluent to improve its purity.

5, the use of appropriate detection methods, such as gas chromatography, mass spectrometry and other technologies to detect the active diluent to ensure that it meets the required purity and chemical characteristics requirements.
