Abstract: A process comprising reacting an aliphatic carboxylic ester compound with acetonitrile in the presence of a metal alkoxide to yield a metal salt of a beta -ketonitrile compound, subsequently transferring the salt to an aqueous medium, and neutralizing the solution to obtain the beta -ketonitrile compound in a free state, wherein a water-immisible organic solvent and water are added to the reaction mixture containing the beta -ketonitrile compound metal salt yielded to transfer the metal salt to the water, the resultant aqueous solution of the beta -keto-nitrile compound metal salt is separated from the organic solvent by phase separation or another technique and then neutralized, and the resultant free beta -ketonitrile compound is taken out by extraction with an organic solvent.

Abstract: PCT No. PCT/JP90/00024 Sec. 371 Date Sep. 9, 1991 Sec. 102(e) Date Sep. 9, 1991 PCT Filed Jan. 11, 1990 PCT Pub. No. WO91/10622 PCT Pub. Date Jul. 25, 1991.A water purifying cartridge including a double structure container having an outer container and an inner cylinder disposed within the outer container, an inlet port for flowing water into an external space defined by the outer container and the inner cylinder, and an outlet port for discharging water from the internal space formed within the inner cylinder, the external space and the internal space communicating with each other through a water channel formed in the inner cylinder and separated by a filter, the external space being filled with activated carbon and the internal space being loaded with separation- and filtration membranes, whereby water flowed into the external space from the raw water supplying portion via the inlet port being arranged to pass through the activated carbon, then introduced into the internal space via the water channel, then purified during the passage through the separation- and filtration membranes, and then discharged from the purified water outlet portion via the outlet port.
