FIELD: chemistry.
SUBSTANCE: invention relates to the synthesis of molecular sieves. The method comprises preparing a synthesis mixture which comprises water, a source of hydroxyl ions, a source of an oxide of tetravalent element, a trivalent element source, a source of fluoride ions, and a directing agent Q, selected from the group consisting of 1-methyl-4- (pyrrolidin-1- yl) pyridinium cation, 1-ethyl-4- (pyrrolidin-1-yl) pyridinium cation, 1-propyl-4- (pyrrolidin-1-yl) pyridinium cation, 1-butyl-4- (pyrrolidin-1-yl) pyridinium cations and their mixtures. The mixture is heated at crystallization conditions including a temperature of 100-200°C and time from 1 to 28 days. Material of molecular sieve EMM-17, which is characterized by a specific X-ray diffraction, is obtained.
EFFECT: invention provides a new molecular sieve which is efficient as an adsorbent and a catalyst of hydrocarbon conversion.
