Scope
GB/T 23672-2009 is the English-translated version of 2-乙基蒽醌.
GB/T 23672-2009 is the product standard for 2-ethyl anthraquinone. Clause 1 states that it specifies the requirements, sampling, test methods, inspection rules and the signs, labels, packaging, transportation and storage for 2-ethyl anthraquinone, and that it applies to the quality control of that product; the page gives no exclusions.
The opening pages identify the substance by the molecular formula C16H12O2, a molecular weight of 236.27 calculated from the 2007 international relative atomic masses, and CASRN 84-51-5.
A warning notice placed before clause 1 states that the standard is for personnel with regular laboratory work experience, that it does not point out all possible safety questions, and that users are responsible for adopting suitable safety and health practices and for ensuring compliance with the relevant national regulations.
Clause 3, Requirements, refers the quality requirements to Table 1, which grades the product as Premium grade, First grade and Qualified; the two rows the page shows set the appearance, from a pale yellow powder or flakes to orange chestnut brown lumps or powder, and a melting point on the dry product of not less than 107.0 degrees C for the two higher grades and not less than 106.0 degrees C for Qualified.
Clause 2 cites GB/T 191, GB/T 2384, GB/T 2386-2006, GB/T 6678-2003, GB/T 6682-2008, GB/T 8170-2008, GB/T 9728 and GB/T 9729. The draft on the page breaks off inside Table 1, so the sampling, test method, inspection and packaging clauses announced in clause 1 are not shown. It was issued on 24 April 2009 and has applied since 1 December 2009.
