Analysis of possibility of replacing toxic benzene to less toxic xylene in a heterogeneous technology cellulose triacetate was conducted. The regularities of the heterogeneous acetylation of cellulose with acetic anhydride, acetic acid and xylene in the presence of perchloric acid catalyst was considered. The possibility of side reactions was defined. The conclusion about the need to consider side-reactions with the O-acylation of cellulose was made.
