Reaction Conditions:
with laccase;ammonia in water at 38 - 40;Enzymatic reaction;Temperature;
Steps:
1-3 Example 2
Add 10 grams of DL-alanine and 50 grams of 25% ammonia in a 250 ml single-neck flask, add 60 grams of water for dilution, and stir under the condition of stirring. The temperature of the system rises to 38-40°C, and 0.1 grams of laccase is added. After the reaction is completed for 16-18 hours, the laccase is filtered out and stored in the refrigerator, ready for the next application.The filtrate was directly fed with hydrogen chloride until the pH value of the system reached between 4.3-4.5 to precipitate solids, filtered and dried to obtain 9.2 grams of L-propionamide hydrochloride.The yield is 92% based on the mass of D,L-alanine.
