Foreword
This standard was drafted in accordance with the rules given in GB/T 1.1-2009.
This standard replaces GB/T 1628-2008 "Industrial Glacial Acetic Acid". Compared with GB/T 1628-2008, except for editorial changes
The technical changes are as follows.
--- The product grade has been cancelled, and the product is divided into two models, Ⅰ and Ⅱ (see Chapter 3, Chapter 3 of the.2008 edition);
--- Increased propionic acid index (see Table 1);
--- Added the technical requirements for Type Ⅰ and Type Ⅱ products (see Table 1, Table 1 of the.2008 edition);
--- Modified the calculation result of the titration method for determining the acetic acid mass fraction (see 4.4.2.4,.2008 version 4.5.2.4);
--- Added Karl Fischer Coulomb's electricity method for determining the mass fraction of water, with Karl Fischer method (general method) as the arbitration method (see
4.5);
--- Added gas chromatography external standard method in the determination of formic acid mass fraction (see 4.6.2.5.2);
--- Added test method for propionic acid project (see 4.11).
This standard was proposed by the China Petroleum and Chemical Industry Federation.
This standard is under the jurisdiction of the National Chemical Standardization Technical Committee (SAC/TC63).
