摘要： A method for recovering a cation component of a neutralized-salt type ionic liquid, characterized by comprising a first step, in which an aqueous solution of the neutralized-salt type ionic liquid is mixed with a water-incompatible organic solvent to prepare a liquid separating into two phases, i.e., an aqueous phase and an organic phase, a second step, in which the liquid separating into two phases is mixed with a water-soluble strong alkali so that the amount of the strong alkali is 20% by mass or larger with respect to the water contained in the aqueous phase, thereby regenerating the cations of the neutralized-salt type ionic liquid present in the aqueous phase, into a neutral substance and moving the neutral substance from the aqueous phase to the organic phase, and a third step, in which the organic phase containing the neutral substance is recovered by a liquid-separating operation. By this method, the cation component of an expensive ionic liquid can be easily recovered at low cost as compared with conventional methods.

摘要： Provided are a method of preparing, and use of 1-(2,2-dimethylpropyl)-cyclopropene as an ethylene antagonist that can be formulated as an aqueous emulsion and applicable to plants through immersion or spraying. It was confirmed that the compound can be reliably synthesized and stored by the preparation method disclosed herein, and it was also confirmed that the compound can effectively inhibit ethylene action when formulated as an aqueous emulsion and treated to a plant by immersion or spray treatment; hence, the compound may be used as an ethylene antagonist on plants, as a pre-harvest or post-harvest plant growth regulator, or as a freshness keeping agent.
