Abstract :Eighteen 1,3-diols were synthesized and their structure and distribution ratio for the solvent extraction of boron were studied. Diols with a high distribution ratio insert ignore into journalissuearticles values(D_{Binsert ignore into journalissuearticles values(OH);_3 > 10); were investigated for the requirements of solvent extraction of boron. Their extraction capacity, and solubility in aqueous phase and in organic diluents were investigated by comparison to 2-ethyl-1,3-hexanediol insert ignore into journalissuearticles values(EHD);, which is widely used as a boron extractant. Among a series of 1,3 diols, 1-benzyl-2,2-dimethyl-1,3-propanediol insert ignore into journalissuearticles values(4a); and 2,2,6-trimethyl-1,3-heptanediol insert ignore into journalissuearticles values(3a); were found to have very low solubility in the aqueous phase compared to the others. IPD insert ignore into journalissuearticles values(3a); was found to have a high solubility in aliphatic diluents such as kerosene. IPD, which has good solubility properties for the solvent extraction of boron, was studied in detail, including dependence of pH, diol concentration, and stripping facility, and in various organic diluents.
