Standard Specification for Apparatus for Microdetermination of Alkoxyl Groups
Standard Specification for Apparatus for Microdetermination of Alkoxyl Groups
ABSTRACT This specification covers the design and dimensional requirements for the apparatus used in the microdetermination of methoxyl and ethoxyl groups in organic compounds. This apparatus is composed of a reaction flask, condenser with scrubber, delivery tube, and two types of receivers—one for volumetric analysis, and the other for gravimetric analysis. SCOPE 1.1 This specification covers apparatus for the microdetermination of methoxyl and ethoxyl groups in organic compounds. Note 1: This specification was originally developed by the Committee on Microchemical Apparatus, Division of Analytical Chemistry, American Chemical Society.2 1.2 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.
ASTM E236-66(2022) - Standard Specification for Apparatus for Microdetermination of Alkoxyl Groups defines the apparatus requirements for precise laboratory analysis of methoxyl and ethoxyl groups in organic compounds. Developed by ASTM International, this standard ensures that all apparatus utilized for microdetermination meet strict design and dimensional specifications, supporting reliable and reproducible analytical results.
The standard addresses the need for consistent laboratory equipment-specifically detailing the structure and materials required for reaction flasks, condensers with scrubbers, delivery tubes, and analytical receivers. This standard specification is vital for laboratories performing chemical and microchemical analysis, especially those involved in organic compound characterization.
