Abstract The preparation of different aldehyde content oxycellulose was studied by orthogonal experiments in this paper. The influences of reaction temperature, ratio of cellulose to NaIO_4, pH value of solution were discussed when NaIO_4 was used as the oxidizing agent and α-cellulose as the starting material. The more important factors that affect the aldehyde content of oxycellulose were the temperature and the content of NaIO_4, the less important factors were pH value and the ratio of cellulose to NaIO_4. The best oxidation conditions were determined. When the reaction temperature is 50 ℃, the pH value is 3, the ratio of cellulose to NaIO_4 is 0.5, the oxycellulose with 80% aldehyde content can be obtained. It especially meets with the need of experiment design.
