Standard Test Method for Purity of Methyl Amyl Ketone and Methyl Isoamyl Ketone by Gas Chromatography

SIGNIFICANCE AND USE
This procedure is designed to determine the purity of the two ketones, methyl isoamyl ketone and methyl amyl ketone, and to obtain the concentration of their various impurities, several of which are critical in the application of these solvents.
SCOPE
1.1 This test method covers the determination of the purity of methyl amyl ketone and methyl isoamyl ketone. In addition, the method determines total ketones and various impurities which may include acetone, isopropyl alcohol, methyl propyl ketone, methyl isobutyl ketone, methyl butyl ketone, methyl isobutyl carbinol, mesityl oxide, methyl isoamyl ketone, methyl butyl carbinol, methyl amyl ketone, and diisobutyl ketone.
1.2 Water and acid cannot be determined by this test method. They must be determined by other appropriate ASTM procedures, and the results used to normalize the chromatographic data.
1.3 For purposes of determining conformance of an observed or a calculated value using this test method to relevant specifications, test result(s) shall be rounded “off to the nearest unit” in the last right-hand digit used in expressing the specification limit, in accordance with the rounding-off method of Practice E29.
1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.5 For hazard information and guidance, see the supplier's Material Safety Data Sheet.
1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

3. Summary of Method
3.1 Arepresentative specimen is introduced onto a gas-liquid partition column. The separated components are measured in the
effluent by a detector and recorded as a chromatogram. The chromatogram is interpreted by applying component attenuation and
detector response factors to the peak areas and relative concentrations are determined by relating the individual peak responses to
the total peak response. Water and acidity are measured by Test Methods D1364 and D1613, respectively, and the results are used
to normalize the values obtained by gas chromatography.

5. Apparatus
5.1 Chromatograph—Any gas-liquid chromatographic instrument having either a thermal conductivity or flame ionization
detector and sufficient sensitivity and stability to obtain for 0.01 % impurity in the specimen a recorder deflection of at least 20
mm at a signal-to-noise ratio of at least 5 to 1. A recording integrator or computer data processing system may also be used.
5.1.1 The injection port of the chromatograph must have a volume of at least 1.2 mL to provide for proper vaporization of the
specimen. The use of a smaller injection port or on-column injection causes peak broadening and tailing.
5.2 Column—Four and one half m of 3.2-mm stainless steel tubing packed with 80 to 90-mesh acid-washed, base-washed, and
silanized diatomaceous earth support coated with 10.0 % 20 000 molecular weight polyethylene glycol and a 8.33 % phenyl
methyl (50:50) silicone. A capillary column, capable of the required separation may also be used.
5.3 Specimen Introduction System—Any system capable of introducing a representative specimen onto the column. Microliter
syringes have been used successfully.
5.4 Recorder—A recording potentiometer with a full-scale deflection of 1 mV, full-scale response time of1sor less, and
sufficient sensitivity and stability to meet the requirements of 5.1.
6. Reagents and Materials
6.1 Carrier Gas, appropriate to the type of detector used. Helium or hydrogen may be employed with thermal conductivity
detectors and nitrogen, helium, or argon with flame ionization detectors. The minimum purity of the carrier gas used should be
99.95 mol %. An oxygen removal system is recommended for the carrier gas.
6.1.1 Warning—If hydrogen is used, take special safety precautions to ensure that the system is free of leaks and that the
effluent is vented properly.
6.2 Column Materials:
6.2.1 Liquid Phase—20 000 molecular weight polyethylene glycol and phenyl methyl (50:50) silicone.
6.2.2 Solid Support—Acid-washed, base-washed, and silanized diatomaceous earth, 80 to 90 mesh.
6.2.3 Solvents—Methylene chloride, reagent grade.
6.2.4 Tubing Material—The stainless steel tubing must be of uniform internal diameter and must be clean. Wash the inside of
the tubing with methylene chloride, then water, and finally methyl alcohol and blow dry with nitrogen.
6.3 Standards for Calibration and Identification—Standardsamplesofallcomponentsareneededforestablishingidentification
