FIELD: chemistry, in particular utilization of chlorine-containing waste. ^ SUBSTANCE: claimed method includes passing of organochlorine compound vapors blended with oxygen-containing reaction gaseous mixture through catalyst layer providing oxidation of starting organochlorine compounds. Said catalyst represents geometrically structured system from microfibers with length of 5-20 mum. Catalyst has active centers which are characterized by presence of absorption band in absorbed ammonia IR-spectrum with wave number nu = 1410-1440 cm-1; contains platinum group metal as active ingredient; and glass fiber carrier. Said carrier in NMR29Si-spectrum has lines with chemical shifts of -100±3 ppm (Q3-line) and -110±3 ppm (Q4-line) in integral intensity ratio of Q3/Q4 = 0.7-1.2; in IR-spectrum it has hydroxyl absorption band with wave number nu = 3620-1440 cm-1 and half-width of 65-75 cm-1; has specific surface, measured by BET using argon thermal absorption: SAr = 0.5-30 m2/g; surface area, measured by alkali titration: SNa = 10-250 m2/g, wherein SNa/SAr = 5-30. ^ EFFECT: selective oxidation of starting organochlorine compounds to safe and easily utilizing substances without toxic by-product formation. ^ 3 cl, 4 ex |
