IDENTIFICATION
First identification A, D.
Second identification B, C, D.
A. Infrared absorption spectrophotometry.
Comparison reference spectrum of sodium propionate.
B. Dissolve 0.1 g in a mixture of 2 ml of copper sulphate solution and 2 ml of methylene chloride. Shake vigorously and allow to stand. Both the upper and the lower layer show a blue colour.
C. To 5 ml of solution S add 2 ml of 0.1 M silver nitrate. A white precipitate is formed.
D. Solution S gives reaction of sodium.
TESTS
Solution S: Dissolve 10 g Sodium propionate in carbon dioxide-free water prepared from distilled water and dilute to 100 ml with the same solvent.
Appearance of solution: Solution S is clear and colourless.
pH: 7.8 to 9.2
Dilute 1 ml of solution S to 5 ml with water.
Related substances: By liquid chromatography, to pass the test.
Readily oxidizable substances:
In a ground-glass-stoppered conical flask introduce 10 g of the substance ( Sodium propionate.) to be examined.
Add 100 ml of water and stir to dissolve. Add 25 ml of sodium hypobromite solution and 10 ml of a 200 g/l solution of sodium acetate, stopper the flask and allow to stand for 15 min. Add 10 ml of potassium iodide solution and 20 ml of hydrochloric acid while cooling.
Titrate with 0.2 M sodium thiosulphate, adding 2 ml of starch solution R towards the end of the titration. Carry out a blank titration. The difference between the volumes used in the 2 titrations is not greater than 2.2 ml.
Iron: Maximum 10 ppm.
10 ml of solution S complies with the limit test for iron.
Heavy metals: Maximum 10 ppm.
12 ml of solution S complies with limit test A. Prepare the standard using lead standard solution (1 ppm Pb).
Loss on drying: Maximum 0.5 per cent, determined on 1.000 g by heating in an oven at 105C for 3 h.
Sodium Propionate FCC Food Grade Specifications
CH3CH2COONa
C3H5NaO2 Formula wt 96.06
INS: 281 CAS Number 137-40-6
DESCRIPTION
Sodium Propionate occurs as white or colorless, transparent crystals or as a granular, crystalline powder. It is hygroscopic in moist air. One gram is soluble in about 1 mL of water at 25°, in about 0.65 mL of boiling water, and in about 24 mL of alcohol. The pH of a 1:10 aqueous solution is between 8.0 and 10.5.
Function: Preservative; mold inhibitor.
REQUIREMENTS
Identification:
A. A 1:20 aqueous solution gives positive tests for Sodium.
B. Upon ignition, a sample yields an alkaline residue that effervesces with acids.
C. Warm a small sample with sulfuric acid. Propionic acid, recognized by its odor, evolves.
Assay: Not less than 99.0% and not more than 100.5% of C3H5NaO2 after drying.
Alkalinity (as Na2CO3): Passes test (about 0.15%).
