摘要： The invention provides carbon fibers having mechanical properties equival to or even better than those of the polyacrylonitrile-based carbon fibers from a bituminous material, e.g. coal tar pitch, as the starting material. The starting pitch is first partially hydrogenated in tetrahydroquinoline under specific conditions followed by a heat treatment to give a pitch composition suitable for spinning which can be characterized by several parameters including the proportions of the carbons and hydrogens having different chemical shifts in the NMR analysis. The pitch composition for spinning is then subjected to spinning under specific conditions including the temperature condition for controlling the viscosity behavior of the molten pitch composition determined by use of the Andrade's equation and the pitch filament is then infusibilized in an oxidative atmosphere and carbonized in an inert atmosphere into carbon fibers having a tensile strength of at least 200 kg/mm.sup.2 and a tensile modulus of at least 10 tons/mm.sup.2.

摘要： A process for preparing 2-amino-1-butanol by reacting L-tartarate of 2-amino-1-butanol with an aqueous slurry alkaline earth metal compound in such a way that some L-tartarate of 2-amino-1-butanol remains in the reaction system throughout the entire time of reaction to produce a precipitate of L-tartarate of the alkaline earth metal which comprises crystals which are sufficiently large so that they have excellent filterability and give a high yield of 2-amino-1-butanol. Highly purified 2-amino-1-butanol can be obtained by subjecting the thus obtained filtrate to rectification.

摘要： A method of decomposing a polycarbonate with water in a supercritical or subcritical state. A high-purity dihydroxy compound which is a constituent component of the polycarbonate can be recovered at a high yield by this decomposition method. This decomposition method is environment-friendly because it does not use an organic solvent, easy to be carried out, has a high decomposition rate and rarely causes a side reaction.
