In this application, with a mixture of isomers, it is often referred to as xylenes or xylol. As we know that water is a universal solvent because water has a maximum dielectric constant value that is 78.4. It is not reactive at room temperatures, except by strong oxidizing agents, and some solvents cause swelling. Make sure the 3-sulfulene and maleic anhydride are completely dissolved in xylene (gentle warming) before you bring the mixture to a reflux. Sulfur forms several polyatomic molecules. Therefore, when adding Sulfur into ethanol/water mixture, the ability of Sulfur solubility into this mixture is decided by the amount of used Sulfur and ethanol. Eng. Sulfur Compounds . Hydrotropes are water-soluble, surface-active compounds which can significantly affect the solubility of poorly soluble drugs, most likely due to the formation of organized assemblies within solution.
