以MgCl2·6H2O、AlCl3·6H2O、Na2CO3为原料,采用乙二醇—变频微波—水热法制备了优质镁铝水滑石。样品用XRD、SEM、TEM、IR、TGDAT、N2吸附—解吸进行了物相、粒度、晶体形貌结构、红外分析、热分析和比表面分析。考察了传统水热法、变频微波—水热法、乙二醇—水热法、乙二醇—变频微波—水热法四种工艺对水滑石晶形、结构、分散性、规整性的影响。实验发现,在水热反应体系中加入〖WTBX〗φ〖WTBZ〗=10%的乙二醇,调节变频微波炉反应温度为120 ℃,反应时间为5 h时可获得晶形好、板层结构显著、规整性好、分散性好的优质镁铝水滑石
透射电镜示粒子直径约在200 nm。
A regular nanocrystalline supramolecular MgAl hydrotalcite was prepared via glycolfrequency microwavehydrothermal using MgCl2·6H2O
AlCl3·6H2O
Na2CO3 as raw material as precipitator. Hydrotalcite samples were characterized by Xray diffraction (XRD),scan electron microscope (SEM)
transmission electron microscope (TEM),IR
thermal analysis (TGDTA),and BETN2 surface area measurements. The images of SEM and TEM showed that the hydrotalcite exhibited as a homogeneous and hexagonal sheet. The XRD result indicated that the hydrotalcite was well crystallized. The influences of tradition hydrothermal
frequency microwavehydrothermal and glycolfrequency microwavehydrothermal on the sample character were investigated. A MgAl hydrotalcite with welldefined shape
obvious intercalated structure
well regular quality and welldispersing capability was obtained when glycol volume ratio was 10% at 120 ℃ for 5 h.
