[Content determination] The content of acetyl group below 42.0% shall be determined according to this method. Take about 2.0g of this product, weigh it accurately, put it into a conical flask, add 100ml of acetone and 10ml of water, plug it tightly, stir it with a magnetic stirrer until it is completely dissolved, add 30ml of sodium hydroxide titrant (1.0mol/L) precisely, continue to stir for 30 minutes, heat 100ml of water, wash the inner wall of the conical flask, continue to stir for 2 minutes, cool it to room temperature, add 2-3 drops of phenolphthalein indicator solution, and use sulfuric acid titrant (0.5mol/L) Titrate to the end point, and correct the titration result with blank test. Every 1ml of sulfuric acid titrant (0.5mol/L) is equivalent to 43.05mg of C2H3O. If the acetyl content is higher than 42.0%, this method shall be used for determination. Take about 2.0g of this product, precisely weigh it, put it into a conical flask, add 30ml of dimethyl sulfoxide and 100ml of acetone, tightly plug it, mix it with a magnetic stirrer for 16 hours, precisely add 30ml of sodium hydroxide titrant (1.0mol/L), continue mixing for 6 minutes, stand still for 60 minutes, heat 100ml of water, wash the inner wall of the conical flask, continue mixing for 2 minutes, cool it to room temperature, add 4-5 drops of phenolphthalein indicator solution, Titrate with hydrochloric acid titrant (0.5mol/L) to the end point, add 0.5ml of excessive hydrochloric acid titrant (0.5mol/L) precisely, stir for 5min, stand for 30min, titrate with sodium hydroxide titrant (0.5mol/L) to pink, and correct the titration result with blank test. Every 1ml of hydrochloric acid titrant (0.5mol/L) is equivalent to 21.525mg of C2H3O.
