ASTM E346-08 Analysis of Methanol

ASTM E346-08 Analysis of Methanol

The standard test methods for the analysis of methanol are covered under ASTM E346-08 standard method. These test methods are suitable for manufacturing control and for determining compliance with specification limits for the properties. The values reported are in SI units and are considered standard.

    Scope:

    ASTM E346-08 standard method defines the procedures for the analysis of methanol. These are physical and chemical tests for determining the quality of methanol. The test methods appear in the following sections:

    Test MethodsSections
    Purity of Reagents4
    Safety Precautions5
    Sampling6
    Acidity7 to 9
    Carbonizables10 to 18
    Colour19 to 21
    Distillation Range22 to 24
    Permanganate Time25 to 27
    Specific Gravity28 to 30
    Water31 to 33
    Water Miscibility34 to 37
    Ethanol37 to 47
    Acetone48 to 55
    Trimethylamine56 to 65

    Results:

    Water-insoluble materials present in a solvent expected to be completely water miscible may interfere with many uses of the solvent. Water Miscibility test method provides a qualitative indication of the presence or absence of water-immiscible contaminants. Methanol is miscible (completely mixes) with water. Methanol sample is diluted to 10 volumes with water and the resulting mixture is examined for cloudiness and turbidity.
