Preparation method of Sodium lactate 60%-80% CAS 72-17-3
Add sodium hydroxide to the lactic acid under cooling for neutralization, place it under 50°C under vacuum concentration to remove 80% of the moisture, then leave it for about one week, then neutralize with sodium hydroxide, and then dilute to a certain concentration to obtain the finished product .

 
Identification and content analysis OF Sodium lactate 60%-80% CAS 72-17-3
Identify
Take the sample to ash, and the ash should be alkaline. If acid is added to the ash, bubbles should occur. The lactate and sodium salt tests (IT-20 and IT-28) of the samples were positive.
Content analysis
Method 1: Accurately weigh about 3g of the sample, evaporate it to dryness on a water bath, and then determine it according to the organic acid-base-salt quantitative method (GT-2). 0.25 mole per liter per liter of sulfuric acid is equivalent to 56.03 mg of sodium lactate;
Method 2: Accurately weigh a sample equivalent to 300 mg of sodium lactate, add 60 ml of a mixed solution consisting of 1 part of acetic anhydride and 5 parts of glacial acetic acid, mix, and let stand for about 20 minutes. Use 0.1mol/L perchloric acid in glacial acetic acid for potentiometric titration. At the same time, perform a blank test and make necessary corrections. 0.1 mole per milliliter per liter of chloric acid is equivalent to 11.21 mg of sodium lactate.
