- Abstract
We prepared five heteropolyacid catalyst by one-pot method, the reaction temperature was 65oC, reaction time 8h, hydrogen peroxide 3mL, naphthalene 1000mg, H4PMo11VO40 100mg, naphthalene conversion was 30.3%,the selectivity of naphthol was 46.7%. The heteropoly acids have Keggin structure, but also have some hydroxylations catalytic activity in reaction of naphthalene to naphthol. Among which,the H4PMo11VO40 was best. With the temperature increasing, the conversion of naphthalene and selectivity of naphthol will rise., The conversion of naphthalene and selectivity of naphthol attained optimal value at 65 oC. With the reaction time increasing, the conversion of naphthalene and selectivity of naphthol were increased, and achieved little change at naphthalene conversion after 6h, After 8h ,1-naphthol’s selectivity decreased, 2-naphthol’s selectivity kept smooth. With the increasing of hydrogen peroxide, the conversion of naphthalene and selectivity of naphthol increased. With the increasing amount of catalyst, the conversion of naphthalene and selectivity of naphthol were significantly increased.
