Figure 5. (A) Effects of temperature, (B) WHSV of H₂O₂, and (C) AAL/H₂O₂ molar ratio on the epoxidation of AAL over Re-Ti-MWW. Reaction conditions: catalyst, 1 g; temperature 313 K; AAL/H₂O₂ molar ratio, 1.5 (A and B); H₂O/AAL mass ratio, 4; WHSV(H₂O₂) = 0.4 h^-1 (A and C); 500 rpm. The data were the average values at 45 h after the reaction reached a steady state. WHSV: Weight hourly space velocity; AAL: allyl alcohol.
