Title
Standard Test Method for Aldehydes in Mono-, Di-, and Triethylene Glycol (Spectrophotometric Method)

ASTM International

Publication Date:
Apr 1, 2008

Scope:

This test method describes the spectrophotometric determination of total aldehyde carbonyl content in the range of 0.5 to 50 mg/kg (as acetaldehyde) or 0.3 to 35 mg/kg (as formaldehyde) in mono-, di-, and triethylene glycol (MEG, DEG and TEG). Alkoxyalcohols (hemiacetals), if present, are co-determined, whereas dialkoxyalkanes (acetals), if present, are not. The results provide a measure of the purity of the sample with respect to total aldehyde carbonyl content.

The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

Review the current 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.
