A silicate catalyst prepared which has a mezopore type (MCM-41)
,by manner that condensation where the interaction between Tetra
Ethyl Ortho Silicate (TEOS) with 3-Mercapto Propyl Tri-methoxy
Silane (MPTS), in the presence of superficial active su
bstance
{Cetyl Trimethyl Ammonium Bromide(C 16 TAB)}at room
temperature.
The process of changing the surface hydophilic of the catalyst has
done by using substance( Hexa methyl disilazane), which
symbolized by the symbol (HMDS).
