ASTM E2313-04

Заменен
Standard Test Method for Aldehydes in Mono-, Di-, and Triethylene Glycol (Spectrophotometric Method) — 4 стр.
Значение и использование

Knowledge of the aldehyde content of Monoethylene glycol is required to establish whether the product meets the requirements of its quality specifications.

Область применения

1.1 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.

1.2 The values stated in SI units are to be regarded as the standard.

1.3 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.
