    Abstract: A process for synthesizing a β-lactam in water at a high temperature under a high pressure; and a process for producing a β-lactam. Namely, a process for synthesizing a ß-lactam characterized by reacting aβ-amino acid in water at a high temperature under a high pressure, wherein the β-lactam is synthesized at a high rate by cyclizing the β-amino acid in water at a high temperature of 200 °C or more under a high pressure of 10 Mpa or more; and a process for producing a β-lactam characterized by synthesizing the β-lactam by reacting a β-amino acid in water at a high temperature under a high pressure and then separating and purifying the β-lactam with the use of a column separating agent.

    Abstract: PROBLEM TO BE SOLVED: To provide a substrate introduction method for a reactor under high temperature and high pressure. SOLUTION: A running reaction system is characterized by a constitution in which a means for stably introducing a substrate into a reactor under the high temperature and high pressure are added to the system, namely such means as a high pressure pump, the reactor, a pressure adjuster for adjusting the pressure inside a reaction system, a slurry feed tank, feed liquid balance coils for adjusting the flow rate of the liquid fed into the reactor and the slurry feed tank and and a screw for feeding slurry as constituting components, and a liquid flow is pressed into the reaction system with the high pressure pump to feed a liquid into the reactor and the slurry feed tank, and the pressure of the above feed lines (balance coils) is equalized by the adjustment carried out by the pressure adjuster so that the reaction system is adjusted not to generate the pressure fluctuation in the reaction system, and the substrate in the slurry feed tank is introduced into the reactor by rotating the slurry feed screw. Also, a substrate introduction method for the reactor by using the reaction system is provided.

    Abstract: A method of continuously and quickly degrading a protein into peptides and/or amino acids in supercritical water or high-pressure hot water at around the supercritical point. Namely, a method of continuously and quickly producing peptides and/or amino acids from a protein which comprises using a flow-through type reactor consisting of a substrate-introducing line for supplying a substrate, a pre-heating oven for supplying high-pressure hot water, a reaction oven for heating a liquid reaction mixture and reacting the same and a cooling unit for cooling the liquid reaction mixture, and continuously hydrolyzing the substrate protein supplied into the reaction oven in supercritical water or high-pressure hot water at around the supercritical point under a pressure of 22.05 MPa or above and at a temperature of 375?C or above; and a method of continuously and quickly hydrolyzing a protein by the above-described process. By using this method, it is possible to obtain preparations which are substantially different from the products obtained by the batch method and contaminated with little secondary and tertiary reaction products. Thus, this method is highly useful particularly in, for example, production of physiologically active peptides and pretreatment for the evaluation and analysis of amino acid composition.
