[0017] Example 1
[0018] According to the solid-liquid mass ratio of 1:3, take wheat protein and 5% hydrogen peroxide into a three-necked flask with a stirrer and a thermometer, and then put the three-necked flask in a water bath, set the temperature to 60℃, Heat preservation and stirring at 130r / min for 30 minutes, then put the mixture in the three-necked flask into a ball mill, add steel balls to the ball mill at a ball-to-material ratio of 10:1, and activate the ball mill for 30 minutes; after the above-mentioned ball mill activation, collect the ball mill mixture by weight In terms of parts, take 45 parts of the ball mill mixture, 22 parts of 1.8mol / L hydrochloric acid, 15 parts of acetic anhydride and 4 parts of ammonium persulfate, put them into the autoclave, use nitrogen protection, and increase the pressure to 2MPa, set the temperature to At 78°C, the reaction was stirred at 160r / min for 4h; after the above reaction, it was cooled to room temperature naturally, and the ...
