Description

1.1 These test methods cover the chemical and physical analysis of the commonly available grades of ethylene glycol, diethylene glycol, triethylene glycol, propylene glycol, and dipropylene glycol. The key sections appear in the following order:

1.2 Review the current appropriate Material Safety Data Sheets (MSDS) for detailed information concerning toxicity, first aid procedures, and safety precautions.

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.

1.3 This gas chromatographic test method is intended for the analysis of mixtures of ethylene, diethylene, and triethylene glycols or mixtures of propylene, dipropylene, and tripropylene glycols in which one of the glycols is the principal component and the other two are present in concentrations of 0.1 to not more than 1 %, each. Up to 1 % tetraethylene glycol in triethylene glycol may be analyzed by this test method. The isomers of dipropylene and tripropylene glycol are not completely resolved under the conditions used. Gas chromatographic test methods for determining less than 0.1 % diethylene glycol in ethylene glycol are in accordance with Test Methods E 611.

Note 1

A new gas chromatograhic method for glycols, Test Method E 2409, has been developed by Committee E15.
