Abstract: It has been shown that for providing maximal activity of Na2O-Cr2O3-MoO3/γ-Al2O3 catalyst in the reaction of isoamylenes dehydrogenation to isoprene, the optimal method for its preparation is a sequential impregnation of γ-alumina support by the supported components according to the following scheme: 1) Mo; 2) Cr; 3) Na. (NH4)2Cr2O7 is a preferable chromium precursor for synthesis of the above mentioned catalyst.
