  • Processes for preparing calixarenes
    Patent number: 12049440
    Abstract: This invention relates to a process for preparing a calixarene compound by reacting a phenolic compound and an aldehyde in the presence of at least one nitrogen-containing base as a catalyst to form the calixarene compound. The invention also relates to processes for high-yield, high solid-content production of a calixarene compound, with high selectivity toward a high-purity calix[8]arene compound, without carrying out a recrystallization step.
    Type: Grant
    Filed: December 17, 2021
    Date of Patent: July 30, 2024
    Assignee: SI GROUP, INC.
    Inventors: Cornelius Haase, Ricky Biittig, Allyson Staats, Philip David Atwood, Jim Webb, Kelly Chichak

  • Solubilized alkoxylated calixarene resins
    Patent number: 10875953
    Abstract: This invention relates to an alkoxylated calixarene resin comprising one or more modified calixarene alkoxylate compounds. The invention also relates to a process for preparing a solubilized alkoxylated calixarene resin comprising reacting a phenolic resin mixture, comprising linear phenolic resins and calixarene compounds having phenolic hydroxyl groups, with one or more epoxide-containing compounds to alkoxylate one or more of the phenolic hydroxyl groups of the calixarene compounds to form a solubilized phenolic resin mixture, and reacting the solubilized phenolic resin mixture with one or more alkylene oxides.
