Reference of 33100-27-5. Let’s face it, organic chemistry can seem difficult to learn. Especially from a beginner’s point of view. Like 33100-27-5, Name is 1,4,7,10,13-Pentaoxacyclopentadecane. In a document type is Article, introducing its new discovery.
This work reports the solubility data of dilute sulfur dioxide in 1,4-dioxane, 15-crown-5 ether, polyethylene glycol 200 (PEG 200), polyethylene glycol 300 (PEG 300), and their binary mixtures at 308.15K and 122.66kPa with the SO2 partial pressure ranging between (7.35 and 118Pa). From the solubility data, Henry’s law constants of SO2 in pure solvents were calculated. The results show that the solubilities of SO2 in these four solvents increase linearly with the enhancement of the equilibrium partial pressure of SO2 in the gas phase within the studied regions. Furthermore, the absorption of SO2 in pure 1,4-dioxane, 15-crown-5 ether, PEG 200 are typical physical processes, and the solubility of SO2 in the three solvents decreases in the order: 1,4-dioxane>15-crown-5 ether>PEG 200. But the SO2 absorption in PEG 300 is a physical process accompanied by a chemical process.
