The heterogenization of sulfanilic and sulfonic Acids and their catalytic activity in the liquidphase alkylation of phenol.
The new mesoporous silica modified with sulfanilic and sulfonic acids was synthesized by using rice husk ash (RHA) as the silica source. The solid catalysts were denoted as RHABzSO3H and RHAPrSO3H. The as-synthesized solid catalysts showed good textural and structural properties. Silika berliang...

| Summary: | The new mesoporous silica modified with sulfanilic and sulfonic acids was synthesized by using rice husk ash (RHA) as the silica source. The solid catalysts were denoted as RHABzSO3H and RHAPrSO3H. The as-synthesized solid catalysts showed good textural and structural properties.
Silika berliang meso baru telah terkini disintesis dengan mengubahsuai silica yang diperoleh daripada abu sekam padi (RHA) menggunakan asid sulfanilik dan asid sulfonik. Mangkin yang terhasil dilabel sebagai RHABzSO3H dan RHAPrSO3H.Mangkin yang disediakan mempunyai kualiti tekstur dan struktur yang baik.
