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. Silika berliang meso baru telah terkini disintesis dengan mengubahsuai silika yang diperoleh daripada abu sekam padi (RHA) menggunakan asid sulfanilik dan asid sulfonik
