Significance and Use

3.1 This test method determines the methoxyl and hydroxypropoxyl content of cellulose ethers by a Zeisel-gas chromatographic technique.

3.2 Substitution levels affect solution properties, rheology, viscosity, and many other properties of the polymer.

Scope

1.1 This test method is applicable to the determination of methoxyl and hydroxypropyl substitution content in cellulose ether products by a Zeisel-gas chromatographic technique.

1.2 This test method is not suitable for use for the analysis of hydroxypropyl-cellulose due to its very high substitution level.

1.3 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. For specific hazard statements, see Section 2, 11.1.4, and 11.1.7.

1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
