摘要
Abstract
The acidity of nitrocellulose was determined by water boiling method and ethanol-acetone extraction method,respectively.It was found that ethanol-acetone extraction method could better free the residual acid in the structure of nitrified cotton,and the acidity measured was closer to the real state.The results of the two methods have little effect on the stability of nitrocellulose,but from the viewpoint of operability,analysis time and stability,the ethanol-acetone extraction method is more suitable for routine detection.关键词
