3.12. Acidation reaction of sodium propionate to form acid propionic as followed: CH3COONa + HCI -> CH3COOH + NaCl The reaction is 2nd order reversible. Kinetic study of this reaction is conducted by taken 100ml reaction solution at different time and neutralize the remaining acid HCl with NaOH 0.515N. Temperature is 50C and the feed mixture is equimolar. t, minute 20 50 NaOH, ml 52.5 32.1 23.5 18.9 14.41 10.5 Calculate the volume of batch reactor to produce acid propionic with average 500kg/h. Intermittent time between two batches for feeding, heating to 50C is 20 minutes, for cooling and discarding is 10 minute. Conversion of propionate sodium is 75%. Feed mixture 0.314kg C2H3COONa and 0.12 kg HCI per litre. Assume constant density 1.215kg/ 10 30 0
