摘要:
在浸没循环撞击流反应器中,以九水硅酸钠和硫酸为原料,以表面活性剂十六烷基三甲基溴化铵(CTAB)为分散剂,采用反应-沉淀法制备纳米白炭黑. 确定了制备纳米白炭黑的适宜工艺条件:硅酸钠浓度为0.3 mol/L,硫酸的质量浓度为20%,反应终点pH为5,螺旋桨转速为800 r/min,反应时间70 min, CTAB添加量为0.4g/L. 采用T透射电子显微镜对产品进行表征,纳米白炭黑近似球型,粒径为11 nm左右且分散性较好,纯度高,收率达到98%以上. 实验所制得纳米白炭黑产品达到2010版中国药典的医药级标准.
Abstract:
In the submerged circulating impinging stream reactor, nano silica was prepared by the reaction-precipitate method. Nine water sodium silicate and sulfuric acid were used as raw materials, and cetyltrimethylammonium bromide(CTAB) was used as a dispersant. The optimal technical conditions to prepare nano silica are the concentration of sodium silicate of 0.3 mol/L, the concentration of sulfuric acid of 20%, the pH 5 of reaction ends, the rotational speed of propeller of 800 r/min, the reaction time of 70 mins, and the addition amount of CTAB of 0.4 g/L. The prepared nano silica was characterized by transmission electron microscope. The nano silica is approximately spherical in shape, and its particle size is about 11 nm, meanwhile it has good dispersion and high purity with product yield over 98%. The nano silica meets 2010 pharmaceutical stand.
