  • Patent number: 11014878
    Abstract: The present invention relates to a method for preparing 3-methylthiopropionaldehyde by reacting methyl mercaptan with acrolein, in which deviations in the stoichiometry of methyl mercaptan to acrolein in the reaction to give 3-methylthiopropionaldehyde are compensated for by supplying or by forming 1,3-bis(methylthio)-1-propanol, and also to the use of 1,3-bis(methylthio)-1-propanol as a storage form of methyl mercaptan and/or 3-methylthiopropionaldehyde.
    Type: Grant
    Filed: February 14, 2017
    Date of Patent: May 25, 2021
    Assignee: Evonik Operations GmbH
    Inventors: Stephan Rautenberg, Sascha Ceylan, Martin Koerfer, Judith Hierold, Harald Jakob, Christian Kaiser, Rainer Malzkorn, Thorsten Merker, Anja Nordschild

  • Publication number: 20120283449
    Abstract: A method for performing at least two successive chemical reactions to produce a target compound from at least one first, and at least one second and/or a further reactant, comprising a first reaction and a further reaction in a reaction medium, the reaction medium in contact with a solid heating medium heated by electromagnetic induction and which is located inside the reactor and surrounded by the reaction medium, and the heating medium being heated by electromagnetic induction with the aid of an inductor, an intermediate compound being formed in a first reaction, from which the target compound forms in a further reaction, and at least one reactant, not present in the reactor before the first reaction, being added between the first and the further reaction, and the target compound being separated from the heating medium.
