To pass the test as per monograph
The Test solution shows the same clarity as that of water, or its opalescence is not more pronounced than that of Reference suspension.
Color of solution—
Test solution— Use the Test solution prepared in the test for Clarity of solution.
To pass the test as per monograph
Test solution has the color of water.
Identification— Infrared Absorption 197F , on un-dried specimen.
Peroxide value: not more than 5.
Refractive index: between 1.538 and 1.541 at 20.
Acidity— Neutralize 50 mL of alcohol containing 1 mL of phenolphthalein TS with 0.10 N sodium hydroxide. Dissolve 10 mL of Benzyl Alcohol in 10 mL of the neutralized alcohol, and titrate with 0.10 N sodium hydroxide to the first appearance of a pink color that persists for not less than 30 seconds: not more than 1.0 mL is consumed.
Limit of nonvolatile residue— [NOTE—Ensure that the Benzyl Alcohol to be examined complies with the test for Peroxide value before performing this test.] Evaporate 10.0 g of Benzyl Alcohol on a water bath to dryness, and dry the residue at 105 for 1 hour. Cool in a desiccator, and weigh. The residue weighs not more than 5 mg: not more than 0.05% of nonvolatile residue is found.
