| titleOfInvention | Partially hydrophilized silica gel and its production |
| abstract | PURPOSE: To enable the production of partially hydrophilized silica gel having fine pores which are made hydrophobic in the inside of the pores and having silanol groups on the external surface by treating silica gel having introduced hydrophobic groups on the whole surface with low temp. plasma. n CONSTITUTION: Silica gel (a) having many fine pores (b) on the surface and hydrophobic groups (e) such as alkyl group (propyl, octyl, etc.,) on the inside surface (C) of the pores is subjected to low temp. plasma treatment under about 0.5Torr, 10W150W output, for 10W120min using sealing gas such as O 2 , argon, He, etc. Thus, the silica gel has hydrophobic groups (e) such as octadecyl silyl group, etc., on the inside surface of the pores and silanol groups (f) on the external surface (d). Accordingly, the partially hydrophilized silica gel has excellent characteristics in the field of application for adsorbent, catalyst, analytical carrier, etc., due to coexistence of hydrophobic groups and active silanol group. Further, a useful starting material for prepg. a filler to be used for the reverse chromatographic analysis of components coexisting with proteins is obtd. n COPYRIGHT: (C)1987,JPO&Japio |
