  • Publication number: 20180119186
    Abstract: This method for producing a compound uses a continuous tank reactor which is provided with two or more reaction tanks for producing the compound and with a reaction liquid feeding pipe that feeds a reaction liquid from an upstream reaction tank to a downstream reaction tank, said method being characterized in that the Reynold's number of the reaction liquid that flows in the reaction liquid feeding pipe is configured to be 1800-22000. Furthermore, this compound production system is used in said method for producing a compound, and is formed by housing at least one of the reaction tanks in a portable container.

  • Publication number: 20170101614
    Abstract: Provided is a technique which can easily realize the retention time of the reaction mixture in the reactor suitable for the production quantity by controlling the amount of the reaction liquid in accordance with the production quantity and thus can suppress the amount of a biocatalyst used in a method for producing acrylamide from acrylonitrile by using a biocatalyst. Provided is a method for producing acrylamide from acrylonitrile through a continuous reaction using a biocatalyst in reactors by using two or more reactors connected in series, wherein one reactor A and a reactor B connected to the reactor A on an upstream side are communicated with each other below liquid faces of reaction liquids in both reactors, and the producing method comprises controlling a liquid volume of a reaction liquid in the reactor B by controlling a level of a reaction liquid in the reactor A to be between a disposed position of a communicating port with the reactor B and a full level position.

  • Patent number: 8980588
    Abstract: A method for producing acrylamide from acrylonitrile by a biocatalyst method, wherein both evaporation of acrylonitrile into a gas phase and damaging of a catalyst by stirring are prevented, is provided. In the present invention, the production of acrylamide from acrylonitrile by the biocatalyst method comprises feeding acrylonitrile into an aqueous medium comprising a microbial catalyst.
