Abstract

EL 2-METIL-1-NAFTOL SE OBTIENE MEDIANTE LA ISOMERIZACION DE 2METILENO-1-TETRALONA. PARA LA ISOMERIZACION DEL 2-METILENO-1TETRALONA SE USA UN CATALIZADOR BASADO EN PD, RH O RU QUE HA SIDO PREVIAMENTE TRATADO CON GAS DE HIDROGENO. EL 2-METILENO-1TETRALONA SINTETIZADA A PARTIR DE LA 1-TETRALONA MEDIANTE LA REACCION DE MANNICH PUEDE UTILIZARSE PARA ESTE PROPOSITO.
