FIELD: chemistry. ^ SUBSTANCE: invention claims method of preparation of catalytic composition applied onto a carrier and acceptable for ethane and/or ethylene oxidation to acetic acid, where catalytic composition applied onto carrier includes catalyst of one or more metal components, on a carrier with aluminium alpha-oxide. Method involves the following stages: (a) preparation of suspension of one or more metal components and aluminium alpha-oxide carrier or carrier precedent particles, (b) dispersion drying of suspension, and optionally (c) calcination of dispersion-dried suspension to obtain catalytic composition applied onto carrier. Invention also claims catalytic composition applied onto carrier and obtained by the claimed method, and method of selective ethane and/or ethylene oxidation to acetic acid using the catalytic composition applied onto carrier. ^ EFFECT: high selectivity of target products and reduced COX generation. ^ 44 cl, 2 tbl, 1 dwg, 3 ex |
