The preparation technological conditions of eucalyptus pulp nanocrystalline cellulose （NCC） were optimized by response surface methodology and characterized with fourier transform infrared （FTIR）, X-ray diffraction （XRD）, laser particle size analysis method and transmission electron microscopy （TEM） observation. The results show that optimization of NCC preparation technological conditions was 55 % sulfuric acid concentration, 52 ℃ of reaction temperature and 4 h of hydrolysis time. Under optimization, NCC yield was 65.80 %, which was closed to 66.23 % of response surface methodology predicted values. Determination coefficient of model is 94.63 %, it indicates that model fitting is effective. Prepared NCC is cellulose type I, average particle size of 365.7 nm and rod-like.
