Synthesis and Characterization of Oligoisoprene obtained in Allyl Alcohol Solution in the Presence of Hydrogen Peroxide

The cooligomers of isoprene and allyl alcohol under the action of hydrogen peroxide have been synthesized. Using a solvent of variable composition isopropyl alcohol–allyl alcohol showed that the cooligomer yield doesn’t depend on a ratio of solvent composition. Polymerization of allyl alcohol itself doesn’t take place. The determination of molar weights and hydroxyl group contents in the cooligomers obtained in both alcohols showed that the cooligomer obtained in the allyl alcohol has an increased functionality 3.5 against 2 in single isopropyl alcohols

The Effect of UV/TiO2/H2O2 Process and Influence of Operational Parameters on Photocatalytic Degradation of Azo Dye in Aqueous TiO2 Suspension

In this work a detailed investigation of heterogeneous photocatalytic degradation of Navy blue HE2R 1 (NB), azo dye of the reactive class is presented using UV/TiO2/H2O2 process in the aqueous suspension under 8W low-pressure mercury vapor lamp irradiation. Here we also report about optimization of various experimental parameters such as effect of catalyst concentration, effect of substrate concentration, effect of H2O2 addition.
