Crown calix[4]arenes, method of preparation and use for selective extraction of caesium

PCT No. PCT/FR98/00401 Sec. 371 Date Jan. 27, 1999 Sec. 102(e) Date Jan. 27, 1999 PCT Filed Mar. 2, 1998 PCT Pub. No. WO98/39321 PCT Pub. Date Sep. 11, 1998The invention relates to new calixarenes of formula: in which R1 represents a crown ether chain that includes at least two aryl or cycloalkyl rings, R2 is a hydroxyl or alkoxy group, or the two R2 groups together form a crown ether chain such as R1, and R3 represents a hydrogen atom or an alkyl group. The calixarenes are used to selectively extract caesium from aqueous solutions that notably have high concentrations of sodium.

Calix[4]arene dibenzocrown ethers as caesium selective extractants

A series of 1,3-dialkyloxycalix[4]arene dibenzocrown ethers were synthesized in the fixed 1,3-alternate conformation with good yields by the reaction of 1,3-dialkyloxycalix[4]arenes with dibenzodimesylate in the presence of caesium carbonate. The three dimensional 1,3-alternate conformation was confirmed by X-ray crystal structure. Upon two phase extraction, NMR studies on the ligand-metal complex, single ion and competitive ion transport experiments through a bulk liquid membrane, 1,3-dipropyloxycalix[4]arene dibenzocrown-6, in which two benzo groups are symmetrically attached to the crown-6 linkage, gave one of the most efficient and selective extractabilities for caesium ion over other alkali metal ions. From supported liquid membrane experiments using 1 and 3 as organic carriers, permeation coefficients of the caesium ion were estimated to be 0.42 and 0.27 cm h-1, respectively. The selectivity of caesium over sodium ion was observed to increase with permeation time.
