Abstract
The method of determining sulphate acid ester in unstabilized cellulose nitrates by hydrolysis in acetone/water solution was evaluated. The precision of duplicate determinations for cotton and wood cellulose nitrates containing about 100% sulphate ester was −0.1 to +5.9% and +0.4 to +9.2%, respectively. With cellulose nitrates containing 69–43% and 69–47% sulphate ester, it was +1.8 to +13.4% and +0.4 to +21.0%. The sulphate acid ester content of both unstabilized cotton and wood cellulose nitrates increased with decreasing nitrogen content.
