Abstract

Currently, there's been a surge in attention towards CO2 sorbents among scientists, engineers, and industry experts. CO2, as both an air pollutant and a greenhouse gas, has become a major concern for the environment. These sorbents aren't just for environmental cleanup—they're also proving valuable in various industrial and consumer activities. This presentation concerns the catalytic synthesis of modified poly(2-chloro-2-propen-1-ol) with ethylenediamine (EDA). The process of oligomerization of 2-chloro-2-propen-1-ol is catalyzed by a new monocrystalline oxovanadium(IV) complex compound. We designed the synthesis of a new monocrystalline compound - vanadyl acetylacetonate linked by a water molecule through a hydrogen bond to 3-amino-2-chloropyridine and physicochemical properties were tested by XRD, MALDI-TOF-MS, coupling TG-FTIR, SEM, UV-Vis diffuse reflectance spectroscopy, photoluminescence spectroscopy, and elementary analysis. Novel materials exhibit a nanoporous structure attributed to EDA's presence. Our objective was not only to induce morphological changes but also to enhance CO2 sorption capacity. The new oligomeric materials were characterized by several methods such as NMR, MALDI-TOF-MS, GPC/SEC, FTIR, TG, and DSC. Additionally, we utilized theoretical chemistry methods to pinpoint the most energetically favorable structural configurations of the modified material's oligomer chains. The development of potent CO2 sorbents, coupled with advanced olefin polymerization catalysts, holds promise in reducing greenhouse gas emissions and addressing environmental pollution stemming from plastics. These efforts align seamlessly with the principles of sustainable development, underscoring the significance of our research in contributing to a cleaner, greener future.
