Simple averaging rules were developed to evaluate the physical properties of the copolymers without introducing any adjustable parameters. Sulfur is soluble in the flammable liquid xylene but not in water. Nevertheless, sulfur-containing groups are only slightly polar and seem to have no contribution to intermolecular aggregation . toluene or xylene. Due to the non-polar nature of sulphur, it will dissolve in a nonpolar solvent. The leftover At an exposure between 200 and 500ppm, symptoms can include feeling "high", dizziness, weakness, irritability, vomiting, and slowed reaction time. The partial pressure of solute gas in these experiments was between 3 and 100 kPa. Since one of the paraxylene uses includes the synthesis of PTA, it also serves to make other compounds such as cyclohexanedimethanol, terephthaloyl chloride and various other polymers.

There is very little information available that isolates xylene from other solvent exposures in the examination of these effects. 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. Ethanol (CH3CH2OH) is a polar molecule that exhibits hydrogen bonding. The mixed solvents investigated were various mixtures of DMA and DGM. Xylene is considered a central nervous system depressant, meaning it slows down the central nervous system. These three chemicals are then used to make PET.
