New preparation method for surface-modified inorganic layered compounds

Abstract

New surface-modified inorganic layered compounds have been prepared by the reaction of Zn(OH)₂ with organic oxychlorides in which 71–98% of the OH groups reacted. Their layered structures are similar to those of the layered double hydroxides (LDHs). Although LDHs have cationic charges, the reaction products are uncharged. The interlayer spacings of the reaction products were 8.3–14.8 Å for the products of Zn(OH)₂ with dioxychlorides, and 11.9–16.7 Å for the reaction products of Zn(OH)₂ with monooxychlorides, depending on the lengths of the organic compounds.
