Hydrophobic silica adsorbents for lipids

摘要: There is provided a process for the preparation of highly reactive hydrophobic silica capable lipophilic binding lipids present in aqueous media, particular body fluids. The hydrocarbon substituted utilized first step this may be prepared from hydrophilic silica, suitably pyrogenic silica. This then treated with volatile silicon compound. next comprises treating an alcohol. In order to enable thus produced material selectively adsorb presence protein, substantial non absorption proteins (other than lipoproteins), further carried out. ammonia or amines wherein substituents on amine nitrogen same different. Also included scope invention use above materials procedures absorbing fluids both together and exclusion proteins.
