ASTM D1166-84(2007)

1.1 This test method covers the determination of methoxyl groups in wood and related materials (1 to 7). The test method is applicable to wood sawdust and, by suitable adjustment in size of the test specimen, to fractions isolated from wood and lignin.

1.2 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. Specific precautionary statements are given in Section 6.

Most of the methoxyl in wood is attributable to the lignin. This test method is used extensively in the study of lignin.
