Title:
RESOL BEADS, METHODS OF MAKING THEM, AND METHODS OF USING THEM
Document Type and Number:
WIPO Patent Application WO2007095017
Kind Code:
B1
Abstract:
Resol beads are disclosed, having a relatively narrow size distribution, prepared in high yield by reaction of a phenol with an aldehyde, with a base as catalyst, in the presence of previously-formed resol beads, a colloidal stabilizer, and optionally a surfactant. The resol beads may be thermally treated to prevent sticking and clumping and have a variety of uses, such as in the formation of activated carbon beads.
