FIELD: biochemistry.
SUBSTANCE: invention relates to synthesis of zeolites. Method for producing a non-aluminum-containing boron-containing zeolite material containing the framework of MWW (BMWW). Method includes: (a) BMWW hydrothermal synthesis from a synthesis mixture containing water, a silicon source, a boron source and MWW template compound to obtain BMWW in a mother liquor with a pH above 9, (b) adjusting the pH of the mother liquor obtained in step (a) and containing BMWW to a value within the range from 6 to 9, (c) isolating BMWW from the mother liquor with the adjusted pH obtained in step (b) by filtration.
EFFECT: invention provides an improvement in technological characteristics of the target product.
