Preface
SH/T 1499 "refined adipic acid" is divided into the following parts.
- Part 1. Specifications;
- Part 2. Determination of content - Titration;
- Part 3. Determination of chroma of ammonia solution - Spectrophotometric method;
- Part 4. Determination of ash;
- Part 5. Determination of iron content 2,2 '- bipyridyl spectrophotometric method;
- Part 6. Fast method for the determination of iron content;
- Part 7. Determination of nitric acid content - Spectrophotometric method;
- Part 8. Determination of oxidizable content - Titration;
- Part 9. Determination of the color of the melt;
- Part 10. Determination of moisture content - Thermal weight loss method;
This section is part 4 of SH/T 1499.
This part is based on the rules given in ISO /IEC 1.1-2009.
This part replaces SH/T 1499.4-1997 "Determination of ash in pure adipic acid".
The main changes in this part compared with SH/T 1499.4-1997 are as follows.
- modified standard name;
- Increased detection limits for the method (see Chapter 1);
- The balance is changed from "0.1mg" to "0.01mg". Increased the requirements of the balance (see 5.1,.1997, 5.1);
- the amount of sample is changed from "100g" to "100g or.200g" (see 7.2, chapter 7 of the.1997 edition);
- the exact multiple of the result is changed from "1mg/kg" to "0.1mg/kg" (see 9.1, 9.2,.1997, chapter 9).
This part is proposed by China Petroleum & Chemical Corporation.
This section is under the jurisdiction of the National Chemical Standard Technical Committee Petrochemical Subcommittee (SAC/TC63/SC4).
