Foreword
SH/T 1499 "refined adipic acid" is divided into the following parts:
- Part 1: Specification;
- Part 2: Determination of content – Titrimetric method;
- Part 3: Measurement of ammonia solution colour (in Pt-Co scale) –
Spectrophotometric method;
- Part 4: Determination of ash;
- Part 5: Determination of content of iron - 2, 2’-Bipyridyl spectrophotometric
method;
- Part 6: Determination of content of iron - Fast method;
- Part 7: Determination of content of nitric acid - Spectrophotometric method;
- Part 8: Determination of content of oxidizable compounds – Titrimetric
method;
- Part 9: Measurement of melt colour (in Pt-Co scale);
- Part 10: Determination of content of moisture – Thermogravimetric
method;
This part is part 1 of SH/T 1499.
This part was drafted in accordance with the rules given in GB/T 1.1-2009.
This part replaces SH/T 1499. 1-1997 “Pure adipic acid”.
The main differences between this part and SH/T 1499. 1-1997“Pure adipic
acid” are as follows:
- CHANGE the standard name into “Pure adipic acid - Part 1: Specification”;
- CANCEL the qualified products;
- CANCEL two indicators: oxidizable compounds and melt colour;
- CHANGE the content in superior grade product from “≥ 99.70%” to “≥
99.80%”;
- CHANGE the melting point of superior grade product from “≥ 151.5°C” to
“≥ 152.0°C”;
Pure adipic acid – Part 1: Specification
1 Scope
This part specifies the technical requirements, test methods, inspection rules,
marking, packaging, transport, storage and safety of pure adipic acid.
This part is applied to the pure adipic acid using the cyclohexane as raw
materials, which is subjected to two-step oxidation to produce coarse adipic
acid, AND then decolourized by activated carbon, recrystallized, separated
and dried.
This part also applies to pure adipic acid produced by cyclohexene
hydrochemical method.
Molecular formula: C6H10O4
Relative molecular mass: 146.14 (In accordance with the 2009 international
relative atomic mass).

It may be batched in accordance with the production cycle, production shift, or
product storage silo.
5.3 Sampling method
TAKE sample in accordance with the technical requirements as specified in
GB/T 3723, GB/T 6678, and GB/T 6679, with the sampling amount of not less
than 1000g.
MIX the sample uniformly and PLACE it in two plastic bags; SEAL it and
ATTACH label, indicating such information as the name of the manufacturer,
product name, lot number or date of manufacture, date of sampling, and name
of the sampler. One bag is used for inspection, AND the other bag is preserved
for future reference. The preserved sample shelf period is six months.
5.4 Judgment rules
The product quality inspection department shall carry out the inspection in
accordance with the method as specified in chapter 4, AND the inspection
result shall be judged using the rounding off value comparison method as
specified in GB/T 8170.
5.5 Re-inspection rules
If the inspection results do not comply with the requirements of this part, it shall
double the sample in accordance with the requirements of GB/T 6678 and
GB/T 6679 for re-inspection; if there is still item in the reinspection results
failing to comply with this part, then this batch of products shall be judged as
disqualified.
5.6 Quality certificate
Each batch of exit-factory products shall be accompanied by a quality
certificate, which includes the name of the manufacturer, product name, grade,
lot number, date of production, and this part number.
6 Marking, packaging, transport, and storage
6.1 Marking
The packaging bag shall be indicated of the name and address of the
manufacturer, the name of the product, this part number, the trademark, the lot
number, the grade, and the net content, etc.
6.2 Packaging
