The invention relates to an onium salt, a liquid composition containing the onium salt and cellulose, and a method for recovering cellulose. The invention makes it possible to provide an onium salt having an extremely high ability to dissolve cellulose at temperatures of 100° C. or lower. It also makes it possible to provide a liquid composition containing this onium salt and cellulose, as a composition suitable for the recovery of cellulose, and a method for recovering cellulose efficiently by using such a liquid composition containing the onium salt and cellulose.

facile microwave-assisted synthesis has been developed for the preparation of unsymmetrical sulfide derivatives from 3-mercaptopropionic acid and a wide variety of alkyl, allyl or aryl chlorides or bromides. The synthesis performed in ethanol at 80 or 120 °C using sodium hydroxide as a base, selectively without an offensive smell, generates 3-(alkylthio)propionic acids in good yields. Effects of reaction

piperidones 3-7 were designed and synthesized as novel cytotoxic agents. These compounds displayed potent cytotoxic properties towards human Molt4/C8, CEM, HSC-2, HSC-3 and HSC-4 neoplasms and also to murine L1210 cells. The majority of the compounds have sub-micromolar or very low micromolar IC50 and CC50 values and are significantly more potent than the reference alkylating drug melphalan. Evaluation
