Disclosed is a commercially advantageous method for producing a cyclic disulfonic acid ester with high yield. Specifically disclosed is a method for producing a cyclic disulfonic acid ester represented by the general formula (3) below, which is characterized in that a silver alkanedisulfonate represented by the general formula (1) below and a dihaloalkane represented by the general formula (2) below are reacted in a nonpolar solvent. (1) (2) (3) (In the formulae, X1 and X2 independently represent a chlorine atom, a bromine atom or an iodine atom; and Y and Z independently represent a substituted or unsubstituted alkylene chain which may have a heteroatom in the chain.)
摘要:
The present invention provides hyperpolarizable organic chromophores. The chromophores are nonlinear optically active compounds that include a π-donor conjugated to a π-acceptor through a π-electron conjugated bridge. Macromolecular structures including the hyperpolarizable organic chromophores are also provided.
摘要:
A purification method is disclosed for a predetermined water-insoluble extractant present in a liquid phase composition that additionally contains one or more additional extractants, synthesis reaction starting materials, and reaction byproducts dissolved as solutes in an organic diluent. An ion-containing compound is admixed with the composition to form an extractant/ion complex in the organic diluent phase that has an affinity for a new phase that is greater than the affinity for the first-named phase. The predetermined extractant/ion complex is separated from the diluent by using the new phase affinity, and the extractant/ion complex is preferably although not necessarily recovered. The extractant/ion complex is separated into extractant and ion. The extractant is recovered. Exemplary extractants include polyethers, crown ethers, crown thioethers, calixarenes, polyamines, cryptands, porphyrins and the like.
