  • Process for stabilizing phenolic resins containing calixarenes
    Patent number: 10336898
    Abstract: This invention relates to a process for stabilizing a phenolic resin containing a mixture of linear phenolic resins and calixarenes and a demulsifier composition comprising the stabilized phenolic resins prepared from the process. The process comprises contacting the phenolic resin with an alkylene carbonate, in the presence of a base catalyst, to at least partially alkoxylate the phenolic hydroxyl groups of the calixarenes. This process forms a stabilized phenolic resin with an increased solubility in a hydrocarbon solvent.
    Type: Grant
    Filed: January 19, 2017
    Date of Patent: July 2, 2019
    Assignee: SI GROUP, INC.
    Inventors: Todd Aube, Gennaro Barbiero, Ricky Biittig, James M. Baxter, Jr.
