| abstract |
The present invention relates to functionalized granular silicas, wherein - the pore volume of Hg (<4 µm) is more than 0.80 ml / g, - dQ3 = 10% is more than 400 µm, - dQ3 = 90% is less than 3000 µm, - the ratio of d50 without ultrasound exposure to d50 after 3 minutes of ultrasound exposure is <4.00 and - the carbon content is 1.0-15.0% by weight. The functionalized granular silicas of the invention can be used as a support material, especially as a support for enzymes. |
