Figure 8. Effect of ammonia (A) before and (B) after addition on epoxidation of AAL. Reaction conditions: catalyst, 1 g; (NH4)2CO3 amounts, 5 ppm; temperature, 313-323 K; AAL/H2O2 molar ratio, 1.5; H2O/AAL mass ratio, 4; WHSV(H2O2) = 0.4 h-1; 500 rpm. AAL: Allyl alcohol; WHSV: weight hourly space velocity.
