Abstract: PROBLEM TO BE SOLVED: To provide a synthetic method of an amino acid acryloyl monomer or an amino acid methacryloyl monomer that can protect an optically active site sufficiently exhibiting the properties of amino acid by formation of a copper complex and can permit inexpensive and safe acryloylation or meth-acryloylation and can be resinified through radical polymerization as in the same way in the syntheses of polyvinyl chloride, polystyrene, or the like. SOLUTION: Copper ion is added to an amino acid to form a copper complex at room temperature, then the substitution reaction with an acid chloride is carried out in an aqueous mixed solvent to form an amino acid acryloyl-copper complex or metharyloyl-copper complex, then the copper is removed from the organic solvent phase with a chelating agent at room temperature in a neutral region. The resultant amino acid acryloyl monomer or amino acid methacryloyl monomer is radically polymerized to synthesize a telomer or a polymer.

Abstract: PROBLEM TO BE SOLVED: To provide a synthetic method of an amino acid acryloyl monomer or amino acid methacryloyl monomer and its telomer or polymer wherein an optically active site which sufficiently expresses property of an amino acid is protected by formation of a copper complex, acryloylation or methacryloylation can be also performed inexpensively and safely in water, and they can be resinified by a radical polymerization method similarly to a synthetic method of polyvinyl chloride or polystyrene. SOLUTION: After forming a copper complex at room temperature by adding a copper ion to an amino acid, an amino acid acryloyl-copper complex or methacryloyl-copper complex is produced by a substituting reaction of acid chloride in aqueous mixed solvents, and the copper is extracted from the organic layer with a chelating agent at room temperature and at a neutral region to be removed. Further, the telomer or polymer is synthesized by radically polymerizing the obtained amino acid acryloyl monomer or amino acid methacryloyl monomer.

Abstract: PROBLEM TO BE SOLVED: To provide the methods for separating and purifying carbon material that comprises the removal of resol resin or novolak resins from the carbon material without damage to the carbon material at a low temperature efficiently without occurrence of injurious or harmful substance on the outside of the system and provide the purification of the carbon material. SOLUTION: A carbon material-containing resin of crushed resol resin or novolak resin is allowed to react in a basic organic solvent of >=0.5 M of alkali concentration and contains 20 to 100 vol.% of water at 300-400 deg.C in the reactor to remove the resol resin or novolak resin component from the carbon material. Then, the carbon material is washed and purified whereby the carbon material is recovered from the carbon material-containing resin.

Abstract: PROBLEM TO BE SOLVED: To enable reinforcing fibers to be separated, recovered, and reused efficiently without damaging the fibers by bringing a fiber-reinforced plastic into contact and reaction with (sub)supercritical water. SOLUTION: After a fiber-reinforced plastic is charged into a reactor 1 and water supplied from a water cylinder 2 to a water tank 3 is charged into the reator 1 through a high-pressure pump 4 so that water occupies 1-50vol.% of the reactor 1, valves 5, 6 are closed and the reactor 1 is hermetically sealed. Then, a heat exchanger 8 and the reactor 1 are heated to 320-500 deg.C with a constant temp. bath 7 to bring water in the reactor 1 into a (sub)supercritical state. The reinforced plastic is brought into contact with the water in a (sub) supercritical state and thus is reacted. The reactor 1 is then returned to normal temp. and the valve 6 is opened to separate and recover a gaseous part contg. hydrocarbons, carbon dioxide, nitrogen, etc., through a trap 9.
