| Abstract: | Dodecanol is selected out as surface modifier on silica surface modification.The effects of dodecanol's dosage,concentration of modifier,time of modification,temperature of modification on modification purpose were researched.By using direct observation and variance analysis,the optimum process condition were as following: dosage of modifier 30mL dodecanol/(10gSiO2),time of modification 70min,and temperature of modification 70℃,under these conditions: settlement volume of product is 3.55mL/g,the degree of activation is 92.85%,the capacity of oil absorption is 2.53mL/g,hydrophobic property of product is very good. |
