Innovative methods of electrodischarge purification of chemical liquids for the synthesis of polymeric materials with predefined properties
https://doi.org/10.15518/isjaee.2025.01.204-217
Abstract
The paper discusses the importance of purifying chemical liquids, particularly monomers, to improve the quality of final products. Impurities in raw materials complicate technological processes, increasing costs and degrading product properties. A new purification method is presented, which uses strong electric fields and discharges to remove impurities. The experiment was conducted on hexene-1, where adsorbents and electrical discharges were employed to enhance purity. Optimal process conditions were identified, such as electrode voltage, linear flow rate, and temperature. Maximum purification efficiency was achieved using silica-based gels due to their microporous structure, which facilitates the penetration of oxygen-containing molecules into the pores of silica gel. The results showed that the purification efficiency is higher when using a weak inhomogeneous electric field, as this is associated with higher field intensity and greater average current. Changes in the composition of hexene-1 before and after purification were detected using infrared spectroscopy. After purification with silica gel, the absorption band corresponding to carbonyl compounds disappeared. The study confirms the high efficiency of the barrier discharge method for purifying hexene-1 and emphasizes the importance of selecting the right adsorbent to optimize the purification process. This method can also be applied to purify other chemical liquids.
