Beschreibung

General description

Silica gel is a rigid 3D network of colloidal silica. It is exclusively used as a support material for the active titanium(III) centers in Ziegler-Natta catalysts. Silica gel allows a controlled fragmentation resulting in the formation of uniform polymer particles with narrow particle size distribution and high bulk density. Silica gel is classified as below:
a. Aquagel - pores are filled with water
b. Xerogel - by the process of evaporation, aqueous phase in the pores are removed
c. Aerogel - solvent removed by supercritical extraction

Application

Silica gel was used to compare MCM-41 type mesoporous adsorbents.[1]

The Effect of Korean Red Ginseng on Bisphenol A-Induced Fatty Acid Composition and Lipid Metabolism-Related Gene Expression Changes.

Joonwoo Park et al.

The American journal of Chinese medicine, 48(8), 1841-1858 (2020-12-11)

Bisphenol A (BPA), which is known to be an endocrine-disrupting chemical (EDC), is associated not only with estrogen activity and reproductive toxicity but also with a variety of metabolic disorders. BPA affects glucose tolerance, cholesterol biosynthesis, and fatty acid synthesis.

Sustainable production of alkyl esters via thermal process in the presence of carbon black.

Eilhann E Kwon et al.

Environmental research, 183, 109199-109199 (2020-02-07)

In this study, it is introduced a sustainable synthetic route of alkyl esters, considered value-added industrial chemicals and fuels, from volatile fatty acids (VFAs) that can potentially be generated from organic waste. In the presence of a porous carbon material

Dissipative water intrusion in hydrophobic MCM-41 type materials.

T Martin et al.

Chemical communications (Cambridge, England), (1)(1), 24-25 (2002-07-18)

Texture-related features of water intrusion in hydrophobised MCM-41 silicas render these materials especially suitable for energy dissipation in mechanical dampers.
