Abstract

：The paper described pillarisations ofnatural bentonite from Pacitan East Java of Indonesia by using AJ and Fe． 1ntercalat[on process by using surfactant molecule has also been carried out．Natural bentonite was intercalated with HDTMA．Br (hexadecyltrimethylammonium．bromide11．5％ solution before pillared with AI and Fe metal to give HDTM A．bentonite forms．The ratio of bentonite and intercalating agent or pillaring agent was 1 gr／50 mL．The mixture was agitated．and then the solid phase was washed with distilled water．Then it was dried and calcined at 450~C for 4 hours．Their catalytic act[v[ty and selectivity were studied for phenol hydroxylation using tIzO2 I3O％1．The reaction condition of this reaction wlds as fo[1ows： rafio of phenol／Iq2()2： ¨ (molar ratio)，concentration of phenoJ： l M．reaction temperature was 60。C．and ratio of catalyst／phenol was I：1 0．The products were hydroquinone and catheco1．
