Title:
CELLULOSE DERIVATIVE, AND BORON ADSORBENT CONTAINING SAID CELLULOSE DERIVATIVE
Document Type and Number:
WIPO Patent Application WO/2023/021551
Kind Code:
A1
Abstract:
Provided is a cellulose derivative which has a high amount of chelate adsorption groups introduced, has high hydrophilicity, and is capable of efficiently recovering boron. This cellulose derivative has a repeating unit represented by formula (I-1) below. In formula (I-1), Ra's are the same or different and are each a hydroxyl group, or a group represented by formula (a) below. In formula (a), R1 represents a hydrogen atom or a methyl group. R2 represents a hydrogen atom, or a hydrocarbon group which may have a hydroxyl group. R3 represents a hydrogen atom or a hydrocarbon group. In addition, at least one of all Ra's contained in the cellulose derivative is a group represented by formula (a) below.
