文摘
- •
Synthesis of cross linked PVA/silica nanocomposite membranes.
- •
Membrane characterizing using FT-IR, SEM, XRD, TGA and DS (swelling degree).
- •
Using membranes to dehydrate reaction mixtures of methyl acetate by pervaporation.
- •
Offering acid conversions, fluxes by varying empirical conditions and silica content.
- •
Optimum acid conversion was found to be 94% by using 20 wt.% of silica content.
