Commonly in liquid form and available in various chemical compositions, solvents are substances that dissolve solutes to form solutions. The amount and type of solute that a solvent can dissolve is dependent upon temperature and polarity.
o-Xylene is an isomeric form of xylene. Experimental values of density (I) and speed of sound (u) of its binary mixtures with diethyl carbonate (DEC) have been evaluated over the temperature range of 298.15-323.15K and at 0.1MPa atmospheric pressure. Its oxidation in the presence of three-dimensionally ordered mesoporous Co3O4 (meso-Co3O4) supported gold (xAu/meso-Co3O4 x 3.7-9.0wt%) nanocatalysts has been reported.
