Sugar acetates, recognized as attractive CO₂-philic compounds, have potential uses as pharmaceutical excipients, controlled release agents, and surfactants for microemulsion systems in CO₂-based processes. This study focuses on the quant. examination of absorption of high pressure CO₂ into these sugar derivatives using quartz crystal microbalance (QCM) as a detector. In addition to the absorption measurement, the QCM is initially found to be able to detect the CO₂-induced deliquescence of sugar acetates, and the CO₂ pressure at which the deliquescence happens depends on several influencing factors such as the temperature and thickness of the film. The CO₂ absorption in α-D-glucose pentaacetate (Ac-α-GLU) is revealed to be of an order of magnitude larger in comparison with its anomer Ac-β-GLU, whereas α-D-galactose pentaacetate (Ac-α-GAL) absorbs CO₂ less than Ac-α-GLU due to the steric-hindrance between the acetyl groups on the anomeric and C4 carbons, implying the significant importance of the mol. structure and configuration of sugar acetates on the absorption. The effects of mol. size and acetyl number of sugar acetates on the CO₂ absorption are evaluated and the conformation and packing of crystalline sugar acetate as well as the accessibility of the acetyls are also vital for the absorption of CO₂. It is addnl. found that a CO₂-induced change in the structure from a crystalline system to an amorphous system results in an order of magnitude increase in CO₂ absorption. Further study illustrates the interaction strength between sugar acetates and CO₂ by calculating the thermodn. parameters such as Henry’s law constant, enthalpy and entropy of dissolution from the determined CO₂ absorption. Experiments and calculations demonstrate that sugar acetates exhibit high CO₂ absorption, as at least comparable to ionic liquids Since the ionic liquids have potential uses in the separation of acidic gases, it is evident from this study that sugar acetates could be used as possible materials for CO₂ separation In the experiment, the researchers used many compounds, for example, (2R,3R,4S,5R,6R)-2-(Acetoxymethyl)-6-(((2S,3S,4R,5R)-3,4-diacetoxy-2,5-bis(acetoxymethyl)tetrahydrofuran-2-yl)oxy)tetrahydro-2H-pyran-3,4,5-triyl triacetate (cas: 126-14-7Electric Literature of C28H38O19).

(2R,3R,4S,5R,6R)-2-(Acetoxymethyl)-6-(((2S,3S,4R,5R)-3,4-diacetoxy-2,5-bis(acetoxymethyl)tetrahydrofuran-2-yl)oxy)tetrahydro-2H-pyran-3,4,5-triyl triacetate (cas: 126-14-7) belongs to tetrahydrofuran derivatives. Solid acid catalysis, and the advantages often associated with their use, have been proved equally efficient for the synthesis of tetrahydrofurans or furans. Oxidations have also proved to be valuable and efficient approaches to chiral tetrahydrofuran derivatives.Electric Literature of C28H38O19
