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.

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
