FIELD: chemistry.
SUBSTANCE: proposed are ZSM-48 crystals, with ratio SiO2/Al2O3 less than approximately 150/1, essentially not containing ZSM-50, and kenyaite, with crystal diametre less than 1 micron, and without fibre morphology. The crystals can have specific cross-shaped morphology. Proposed are versions of the method of producing ZSM-48 crystals using heterostructure zeolite primers, which are not ZSM-48 and ZSM-50 primers.
EFFECT: obtaining crystalline zeolite ZSM-48 with high phase purity and high activity.
