Novel hydrotalcites, syntheses, and uses

摘要

Synthetic hydrotalcites of the general formula [M2+1-xM3+x(OH)2]x+[An-x/n.mH2O]x-where M2+ is a divalent cation, M3+ is a trivalent cation and An- is an organic anion selected from straight chain carboxylates of C16-C18 acids, carboxylates of aromatic acids, carboxylates of acrylic acid, unsaturated carboxylates of methacrylic acid, unsaturated carboxylates of vinylacetic acid and C2 and higher organic acids containing heteroatoms such as nitrogen, phosphorous, sulfur and halogens are disclosed, along with methods of synthesis and uses.
