Light and Heavy Liquid Paraffin, Light Mineral Oil and Mineral Oil
CAS Number: 8042-47-5 or 8012-95-1
Light and Heavy Liquid Paraffin, Light Mineral Oil and Mineral Oil
Specifications of Light Mineral Oil USP NF Grade:
DEFINITION
Light Mineral Oil is a purified mixture of liquid hydrocarbons obtained from petroleum. It may contain a suitable stabilizer.
IDENTIFICATION
A. Infrared Absorption
B. It meets the requirements in Specific Tests for Viscosity—Capillary Methods.
Limit of Polycyclic Aromatic Hydrocarbons:
To pass the test.
Acceptance criteria: The absorbance at any wavelength in the specified range of the Sample solution is NMT one-third of the absorbance of the Standard solution.
Specific Gravity: 0.818–0.880
Viscosity Capillary Methods:3.0–34.4 mm2/s for kinematic viscosity, measured with a capillary viscometer at 40 ± 0.1C
Acidity:
Sample solution: Combine 10 mL of Light Mineral Oil and 20 mL of boiling water, shake vigorously for 1 min, and allow to cool. Remove, and filter the aqueous layer.
Analysis: To 10 mL of the Sample solution add 0.1 mL of phenolphthalein.
Acceptance criteria: The solution does not produce a pink color. NMT 1.0 mL of 0.01 N sodium hydroxide is required to produce a pink color.
Readily Carbonizable Substances Test:
To pass the test.
Solid Paraffin:
Sample: Light Mineral Oil that has been dried previously in a beaker at 105c for 2 h and cooled to room temperature in a desiccator over silica gel
Analysis: Fill a tall, cylindrical, standard oil-sample bottle of colorless glass of 120-mL capacity with the Sample. Insert the stopper, and immerse the bottle in a mixture of ice and water for 4 h.
Acceptance criteria: The Sample is sufficiently clear that a black line 0.5 mm in width, on a white background, held vertically behind the bottle, is clearly visible.
Limit of Sulfur Compounds:
Solution A: Saturated solution of lead(II) oxide in sodium hydroxide (200 mg/mL)
Sample: 4.0 mL
Analysis: Combine the Sample, 2 mL of dehydrated alcohol, and 2 drops of Solution A, heat at 70C for 10 min with frequent shaking, and cool.
Acceptance criteria: No dark brown color develops.

Limit of Polycyclic Aromatic Hydrocarbons:
To pass the test.
Acceptance criteria: The absorbance at any wavelength in the specified range of the Sample solution is NMT one-third of the absorbance of the Standard solution.
Specific Gravity: 0.845–0.905
Viscosity Capillary Methods: 34.5–150.0 mm2 ·s –1 for kinematic viscosity, measured with a capillary viscometer at 40 ± 0.1C.
Acidity:
Sample: 10 mL
Analysis: Add 20 mL of boiling water to the Sample, and shake vigorously for about 1 min. Allow to cool, and draw off the separated water. To 10 mL of the filtered aqueous layer add 0.1 mL of phenolphthalein.
Acceptance criteria: The solution does not produce a pink color. NMT 1.0 mL of 0.01 N sodium hydroxide is required to produce a pink color.
Readily Carbonizable Substances Test:
To pass the test.
Acceptance criteria: The oil portion of the Sample may turn hazy, but it remains colorless or shows a slight pink or yellow color, and the acid portion of the Sample does not become darker than the Standard solution.
