  • METHOD FOR PRODUCING ISOCYANURATES FROM URETDIONES
    Publication number: 20220348708
    Abstract: The invention relates to a process of preparing allophanate- and/or thioallophanate group-containing compounds comprising the following steps: reacting A) at least one component having at least one uretdione group with B) at least one component having at least one hydroxyl and/or thiol group, in the presence C) of at least one catalyst, containing a structural element of the general formulae (I) and/or (II), wherein R1, R2, R3, R4, R5 and R6 independently of each other represent the same or different radicals meaning saturated or unsaturated, linear or branched, aliphatic, cycloaliphatic, araliphatic or aromatic organic radicals with 1 to 18 carbon atoms that are substituted or unsubstituted and/or have heteroatoms in the chain, the radicals being capable of forming, even when combined with each other and optionally together with an additional heteroatom, rings with 3 to 8 carbon atoms that can optionally be further substituted, wherein R3, R4, R5 and R6 independently of each other also can represent hydrogen
    Type: Application
    Filed: July 6, 2020
    Publication date: November 3, 2022
    Inventors: Hans-Josef Laas, Florian Stempfle, Kai Laemmerhold, Saskia Beuck, Raul Pires, Christoph Guertler, Nusret Yuva, Ralph-Georg Born, Daniel Thiel, Tuba Fatma Bayram, Sureshbabu Guduguntla, Walter Leitner
