The solvent extraction has been successfully applied to the recovery of methyl-substituted 1,3-dioxane from the aqueous reaction media. Aromatic hydrocarbons used as extractants allowed the removal, from the aqueous phase, of up to 75% of dioxane for

This paper presents sorption properties of CaCl2/SiO2 composites synthesized by a sol-gel approach. Desorption isobars measured at T=30–140°C and vapor pressure 12.8–81.0 mbar clearly show a correlation between the sorbents pore structure and th
