N-Acetyl-DL-methionine → L-Methionine

Participants

Reaction Steps

100 g of the above catalyst was swelled in water for about one hour and packed into a jacketed glass column having 2.5 cm diameter and 80 cm height and kept at 50° C. Solution of N-acetyl-DL-methionine (0.2 mol, pH 7.0, added with 5.0×10-4 mol CoCl2) was continuously flown down from the top of the column at a flow rate of 1000 ml/hr. The reaction solution flown out of the bottom of the column was sampled on every certain interval of time and the amount of the L-methionine produced was determined by way of ninhydrine colorimetry. The results are shown in table 6.
