Method for producing a silane, method for modifying a silica with the silane, and modified silica |
| abstract |
The invention relates to a process for preparing a silane, to a process for modifying a silica with the silane, and to a modified silica. n The process for preparing a silane of the formula I) comprises at least the following steps:n a) providing a substance (R 1 ) o Si—R 2 —HNC(═O)NH-A-NH 2 ; b) providing a substance HOC(═O)-A-S 2 -A-C(═O)OH; c) activating the substance from step b) through reaction with oxalyl chloride to form ClC(═O)-A-S 2 -A-C(═O)Cl; d) reacting at least two equivalents of the substance from step a) with one equivalent of the substance from step a), thereby obtaining a silane of the formula I); e) optionally purifying the silane of the formula I) obtained in step d)n n(R 1 ) o Si—R 2 —HNC(═O)NH-A-HNC(═O)-A-S k -A-C(═O)NH-A-NHC(═O)—R 2 —Si(R 1 ), I)n nwherein the groups A within a molecule may be identical or different and are aromatic groups. |
