RESIN GRAINS AND USE THEREOF IN PROCESSING AQUEOUS SOLUTIONS Russian patent published in 2020 - IPC C08F8/42 C08J3/12 C07H1/06 

FIELD: chemistry.

SUBSTANCE: disclosed is resin grain containing functional groups, based on vinyl polymer for processing aqueous solutions containing one or more sugars and/or one or more sugar alcohols, containing functional groups having structure (S1)

,

where -X- contains one or more structures (S7), one or more structures (S8), one or more structures (S9) or a combination thereof, where structure (S7), structure (S8) and structure (S9) are defined as follows:

where the aromatic ring in structure (S9) can be substituted or unsubstituted, and where each of R1 and R2 is independently selected from a group consisting of hydrogen, hydroxyl, amino, unsubstituted alkyl and substituted alkyl, and where R3 is selected from a group consisting of hydrogen, unsubstituted alkyl and substituted alkyl, where -Y is structure (S5):

,

where -A5- is structure (S8):

,

where each of R1 and R2 is independently selected from a group consisting of hydrogen, hydroxyl, amino, unsubstituted alkyl and substituted, wherein mole ratio of multivalent atomic cations to -X- groups is either 0:1 or 0.01:1 or less. Invention also relates to a set of resin beads.

EFFECT: technical result is efficient separation of sugars using resin grains characterized by relatively large average diameter and relatively high homogeneity coefficient.
