    摘要: According to the present invention, a method of producing ethers, which includes subjecting a conjugated diene compound and an alcohol to a telomerization reaction in the presence of a composition containing a palladium compound, an isocyanide represented by the formula (I) R1R2R3CNC   (I) and a base represented by the formula (II) M(OR4)n   (II) as a catalyst is provided. According to the method of the present invention, by telomerization reaction of a conjugated diene compound and an alcohol, ethers can be produced industrially advantageously. (In the above-mentioned formulas, each symbol is as defined in the specification.)

    摘要: There is provided a process for separating at least one phase transfer agent (PTA) from an organic liquid mixture containing at least one organic solvent and at least one PTA, in which the organic liquid mixture is brought into contact with one surface of a selectively permeable membrane and pressure is applied to the organic liquid mixture which causes a fraction of the organic liquid to permeate through the membrane and exit at the other surface, such that the concentration of the at least one PTA in the fraction of organic liquid which does not permeate the membrane increases while the concentration of the at least one PTA in the fraction of organic liquid which permeates through the membrane is less than the concentration of the at least one PTA in the original mixture.
