Abstract: PROBLEM TO BE SOLVED: To obtain a conjugate filament having high nitrile content, excellent in processability and useful for woven or knitted fabric, nonwoven fabric, or the like by including plural specific polymers arranged in core-sheath configuration. SOLUTION: This conjugate filament having high nitrile content comprises two or more kinds of polymers arranged in sheath/core configuration. The sheath polymer is selected from the group consisting of an acrylonitrile olefinic unsaturated polymer composed of 50-95 wt.% acrylonitrile monomer and 5-50 wt.% olefinic unsaturated monomer such as methyl methacrylate, an organic polymer such as a polypropylene and a combination thereof. The sheath component content is 99-1%, preferably 90-10% based on the filament. The core polymer is selected from the group consisting of the above acrylonitrile olefin-based unsaturated polymer, the above organic polymer and a combination thereof, but the core polymer is different in the composition from the sheath polymer. The core component content is 1-99%, preferably 10-90% and is thermally stable.

Abstract: PROBLEM TO BE SOLVED: To obtain a highly purified acetonitrile applicable to chromatography in a few process and a low cost by subjecting crude acetonitrile as a by-product in producing acrylonitrile to distillation and an ion exchange resin treatment. SOLUTION: The objective compound is obtained by distilling crude CH3 CN by using three distilling columns having overhead reflux loops of respectively having a reflux ratio higher than (3:1), (3.4:1) and (6.4:1), in turn, under >=1 atm., to remove HCN and generating a bottom product containing (A) a CH3 CN/ water azeotropic mixture and water, separating the component A to (B) a CH3 CN/water azeotropic mixture having a higher CH3 CN concentration and a bottom product containing water under =1 atm., then generating a CH3 CN/water azeotropic mixture containing substantially whole amount of water derived from the component B, a bottom product containing CH3 CN and heavy organic compounds, and a side stream containing (C) a highly purified CH3 CN, thus purifying the component C by an acidic ion exchange resin.

Abstract: PURPOSE: To obtain a catalyst useful for preparation of vinyl acetate by milling a fixed bed catalyst precursor comprising Pd-Au, or the like, supported on a fixed bed catalyst support with a fluid bed catalyst binder to form a slurry, drying the slurry, and impregnating the obtained microspheroidal particles with a solution of alkali metal salt. CONSTITUTION: A slurry is formed by milling a fixed bed catalyst precursor comprising Pd-M (M is Au, Ba, Cd, Bi, Cu, Mn, Fe, Co, Ce, U or their mixtures) on a fixed support (example, silica sphere) with a fluid bed catalyst binder (for example, aqueous slurry of inactive support such as silica). The slurry is dried to form microspheroidal particles of a solid fluid bed catalyst precursor, and the particles are arbitrarily impregnated with a solution of alkali metal salt to form a fluid bed catalyst. The catalyst has a structure of Pd-M-A (A is an alkali metal, M is a present in the range of 0 - about 5 wt.%, and A is present in the range of 0 - about 10 wt.%).
