Abstract
(EN)
FIELD: chemistry. SUBSTANCE: described is method of molecular sieve ZSM-23 obtaining, which includes: a) preparation of mixture, capable of formation of claimed molecular sieve; and claimed mixture includes sources of alkaline or alkaline-earth metal (M), oxide of trivalent element (X), oxide of tetravalent element (Y), water and structure directing agent (R) of formula (CH3)3N+CH2CH2CH2N+(CH3)2CH2CH2CH2N+(CH3)3, and has composition, in molar ratio, within the following ranges: YO2/X2O3 from 25 to 29, H2O/YO2 from 5 to 100, OH-/YO2 from 0,05 to 0,5, M/YO2 from 0,05 to 0,5, R/YO2 from >0 to <0,5, and b) exposure of claimed mixture in conditions, sufficient for obtaining claimed ZSM-23, where mentioned sufficient conditions include temperature from nearly 150 to 200°C. Described is method of dewaxing of wax-containing raw material by izomerisation of paqraffins, in presence of molecular sieve ZSM-23, obtained by method described above. EFFECT: increase of catalytic activity. 12 cl, 7 dwg, 2 tbl, 13 ex
