Foreword
This standard and ISO 6353-3. 1987 "Chemical analysis of reagent --- Part 3. Specifications second series" R52 "n-butanol" consistency
Not equivalent.
This standard replaces GB/T 12590-1990 "Chemicals n-butanol," compared with the GB/T 12590-1990 main changes are as follows.
--- AR content of the "99.0%" to "99.5%" (1990 version 3.1, Chapter 4 of this edition);
--- Acidity of the unit by the "mmol/100g" adjusted "mmol/g" (1990 edition 3.4, edition Chapter 4);
--- Improved method for measuring the ester (1990 version 4.4.5, this version 5.9).
