以自制的β-Zn(OH)2和氨基苯甲酸为原料,水热合成了具有层状碱金属盐(LBMS)结构的氢氧化氨基苯甲酸锌化合物。通过XRD、TG-DTA、SEM和TEM分析研究了合成产物的结构、形貌和热稳定性,探讨了合成条件对水热反应产物的影响及合成产物在有机溶剂中的剥离反应。当o-NH2C6H4COOH/Zn的摩尔比为1.2,水热温度70℃下反应12h时,得到的层状物具有板块状粒子特征,层间距为1.33nm;当m-NH2C6H4COOH/Zn的摩尔比为1.8,水热温度40℃下反应24h时,得到的层状化合物具有纤维状粒子特征,层间距为1.08nm。合成的层状物在醇溶剂中可发生剥离反应,层状氢氧化邻氨基苯甲酸锌在正丁醇中的剥离量为0.12g.L-1,层状氢氧化间氨基苯甲酸锌在乙醇中的剥离量为0.18g·L-1。
A zinc hydroxide aminobenzoate compound with a layered alkali metal salt (LBMS) structure was hydrothermally synthesized from the homemade β-Zn (OH) 2 and aminobenzoic acid. The structure, morphology and thermal stability of the synthesized products were investigated by XRD, TG-DTA, SEM and TEM. The effects of synthesis conditions on the hydrothermal reaction products and the stripping reaction of the synthesized products in organic solvents were also discussed. When the molar ratio of o-NH2C6H4COOH / Zn was 1.2 and the hydrothermal temperature was 70 ℃ for 12h, the obtained layered product had platelet-like particle characteristics and the interlayer spacing was 1.33nm. When the mole ratio of m-NH2C6H4COOH / Zn was 1.8 , The hydrothermal temperature of 40 ℃ for 24h reaction time, the resulting layered compounds with fibrous particles, the layer spacing of 1.08nm. The delamination reaction of the synthesized layer in the alcohol solvent was carried out. The amount of delamination of the layered zinc o-aminobenzoate in n-butanol was 0.12 gL-1, and the lamellar zinc o-aminobenzoate in ethanol The amount of peel was 0.18 g · L -1.
