The present paper describes the influence of TiO2 catalyst and of UV pretreatment of reaction mixture abies sawdust-CH3COOH-H2O2-catalysts TiO2 on the yield and composition of cellulosic product. The significant increase of the delignification activity as a result by the use of photochemical pretreatment of reaction mixture with TiO2 catalyst was established. Optimum parameters of abies wood delignification resulting in the high yield of cellulosic product with low residual lignin content has been selected.
