Synthesis of a low-carbonate high-charge hydrotalcite-like compound at ambient pressure and atmosphere
- Pacific Northwest National Lab., Richland, WA (United States)
To our knowledge, only one report of low-CO{sub 3} HTLCs having a layer charge {ge}0.33 has been published, and these samples had between 15 and 33% of the interlayer sites occupied by CO{sub 3}{sup 2-}. In this communication, we report a new synthetic route under ambient pressure and atmosphere leading to a high-charge HTLC nearly free of inorganic C. This HTLC, which we synthesized with an x value of 0.45, consists of Mg{sup 2+} and Al{sup 3+} as the structural cations and the terephthalate dianion [C{sub 6}H{sub 4}(COO{sup -}){sub 2} or TA] as the compensating anion. 16 refs., 2 figs., 1 tab.
