This thesis mainly magnesium aluminum , magnesium , iron and zinc aluminum hydrotalcite , fumaric acid isomer ( maleic acid and fumaric acid ) is an organic anion object using ion exchange hydrotalcite class laminar compound and butenedioic isomer anion intercalation reaction . Were characterized by means of XRD, IR and TG analysis of the the intercalation product obtained crystal structure characteristics . The study showed that: hydrotalcite and zinc aluminum hydrotalcite are present in various solvents fumaric acid isomers anion intercalation selectivity than maleic acid , fumaric acid preferential access to the inter-layer various characterization results intercalation product having a better crystal structure ; MgFe talc is difficult to be subjected to ion exchange and object laminates , and in the reaction is easy to destroy . This paper also uses the Gaussian-98 package of ab initio molecular orbital method (HF/6-31G) to calculate the molecular structure of cis fumaric acid isomers anion , and combined with the experimental data analysis from the point of view of the microscopic role the LDHs interaction between subject and object in the system plug layer process , selective intercalation process to determine the impact of the law and the intercalation mechanism . The results showed that , The intercalation -LDHs butenedioic isomer anion selectivity and the oxygen atom of the anion electrical Hobb Habitat, spatial configuration, dipole closely related , theoretically discloses fumaric acid ratio maleic acid is easy to enter the the hydrotalcite layer between the possible causes . In addition , the paper also examines the influence of temperature , solvent , and the ratio of mixed acid solution intercalation selectivity . The results show that in the aqueous solution , the Mg-Al LDHs system , the reaction temperature may affect the the interpolation layer selectively , when the temperature is below 40 ° C , of maleic acid, the reaction is greater than the fumaric acid ,
