"N-Butyl Acetate for Industrial Use (GB/T 3729-2007)" has made some adjustments based on the original version for the convenience of use: the chromaticity index of qualified products is changed from ≤20 to ≤10, and the density index is changed from (0.876 ～0.883) g/cm3 was revised to (0.878～0.883) g/cm3; the test methods for appearance, n-butanol content and odor were added; the determination method for n-butyl acetate content was added by capillary column gas chromatography and determined as the arbitration method ; The Karl Fischer Coulomb method was added for the determination of moisture and determined as the arbitration method; the method for the determination of density was modified from the Webster balance method to the densitometer method; the safety clause was added.

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. used 10% polyethylene adipate/401 organic support packed column to determine industrial n-butyl acetate, among which moisture, n-butanol, n-butyl acetate, and the separation was good, The peak shape is symmetrical, and the results are accurate and reliable.
