Acetate is dissolved with acetone from a known dry mass of the mixture. The residue is collected, washed, dried and weighed; the corrected mass if necessary, expressed as a percentage of the dry mass of the mixture. The percentage of acetate is found by difference.
Add 100 ml of acetone per gram of sample to the sample in the flask, shake the flask, let it stand at room temperature for 30 minutes and then drain the liquid from the weighed filter crucible.
Repeat the process two more times (making three extractions in total), but only for 15-minute periods, so total processing time in acetone is 1 hour. Flush residue into filter crucible with acetone and suction off. Refill the crucible with acetone and let it drain under gravity. Finally, drain the crucible by suction, dry the crucible and residue, then cool and weigh.
