Pyrogallol-formaldehyde resin

In Table I the data for systems that strongly adsorbed both W and are summarized. Table II contains data on those systems which strongly adsorb only . In Table III the systems that poorly adsorbed W are described. The effect of acidity on the adsorption of W and onto a pyrogallol-formaldehyde chelate resin is summarized in Table IV. The values of W and ... [Pg.155]

Manecke described the preparation and properties of several resins prepared by the condensation of hydroquinone, pyrogallol, resorcinol, or pyrocatechol with phenol and formaldehyde. [Pg.319]

The pyrogallol was reacted with formaldehyde to give resins comparable with those made from phenol.47 Per-... [Pg.367]
