摘要
研究了十六烷基三甲基溴化铵/环己烷/水/正己醇体系微乳液的组成和性质以及电解质、温度对此体系的影响.结果表明:当十六烷基三甲基溴化铵与正己醇的摩尔比为1∶3时,该体系有较宽且稳定的相区;在该体系中制得的Mg(OH)2沉淀,其平均粒径为150 nm左右;在马弗炉中500℃下煅烧2 h制得的MgO,在电镜下观察粒子没有团聚现象,且MgO粒子粒径分布均匀,平均粒径为30 nm.
The microemulsions were prepared by cetyltimethyl ammonium bromide,cyclohexane, H2O and n- hexanol,and its composition and properties were studied. The results were shown as follows： when the mole ratio of cetyltimethyl ammonium bromide to n - hexanol was 1 ： 3 at 30℃ the W/O microemulsion formation was steady in a wide region. The particles size of Mg（OH）2 obtained in above system was 150 nm. Further,and the Mg（OH）2 sample had been burnt for 2 h in muffle furnace at 500℃ to form nanoparticles of MgO. Agglomeration of Nano -particles of MgO was not observed in TEM and well distributed,and particles size on average was 30 nm.
