KUGELFOERMIGES MIKROPOROESES SILICA-GEL UND VERFAHREN ZU SEINER HERSTELLUNG |
摘要 |
A spherical micro-porous silica gel, which is characterized by having a mean diameter of 3-20 mu m, a bulk density of 0.28-0.41 g/cm3, a pore size of 18,000-100,000 and a specific surface area of 1,000-1,400 m2/g and a production process therefor is characterized by employing (a) an aqueous solution containing SiO2 in which the primary particle diameter is not larger than 6 nm and the molar ratio of SiO2 to Na2O is not larger than 5.5, (b) either stearic acid or a mixture of stearic acid and a non-ionic surface active agent of which HLB ranges from 3.5 to 6.0 as an emulsifier and (c) an organic acid as a gelling agent. |
