Synthetic Route of 14098-44-3, An article , which mentions 14098-44-3, molecular formula is C14H20O5. The compound – Benzo-15-crown-5 played an important role in people’s production and life.
The solvent extraction of rubidium and caesium picrates has been studied at 25 deg C with mixtures of crown ether and tributyl phosphate (TBP) or trioctylphosphine oxide (TOPO) in benzene, and the adduct-formation constants in the benzene solution have been calculated. The crown ethers used in this work were 12-crown-4 (12C4), 15-crown-5 (15C5), and benzo-15-crown-5 (B15C5). The stoichiometric composition of any extracted complex under the present experimental conditions is alkali metal ion : crown ether : TBP or TOPO : picrate ion = 1:1:1:1. The TOPO complex is more extractable than the corresponding TBP complex. The extractability of the Rb+ complex is larger than that of the corresponding Cs+ complex. For both TBP and TOPO, the adduct-formation constant value sequences of Rb+ and Cs+ are B15C5>12C4>15C5> and 12C4>B15C5>15C5, respectively.
