The present invention relates to granular functionalized silicas, wherein -tthe Hg pore volume (< 4 ?m) is more than 0.80 ml/g, -tdQ3=10% is more than 400 ?m, -tdQ3=90% is less than 3000 ?m, -tthe ratio of d50 without ultrasound exposure to d50 after 3 min of ultrasound exposure is < 4.00 and -tthe carbon content is 1.0-15.0% by weight. The inventive granular functionalized silicas can be used as a support material, especially as a support for enzymes. |
