3 Principle
The acetate is dissolved out from a known dry mass of the mixture, with acetone.
The residue is collected, washed, dried and weighed, its mass, corrected if necessary, is expressed as a percentage of the dry mass of the mixture. The percentage of acetate is found by difference.
4 Reagents
Use the reagents described in GB/T 2910.1 together with that described in 4.1.
