Abstract
The determination of acetyl value in cellulose acetate by Eberstadt method is a time-consuming procedure that does not lend itself well to control the routine operation in industry, although it is now used as the most aconrate method.
The determination of cellulose content in cellulose acetate was easily carried out by applying the bichromate oxidation method for cellulose in cotton.
This procedure, with some improvement, is found particulary rapid and also gives exact results.
The standard deviation and the accuracy of the Eberstadt method and our modified method are discussed by comparison.
