Abstract
PROCEDIMIENTO PARA LA OBTENCION DE NUEVOS DERIVADOS DE PIRAZOL, DE EFECTO HERBICIDA. CONSISTE EN HACER REACCIONAR 1,3-DIMETIL-4-(2,4-DICLOROBENZOIL)-5-HIDROXI-PIRAZOL CON UN HALURO DE ACIDO DE FORMULA GENERAL (II). SE OBTIENE EL COMPUESTO (I) EN QUE X REPRESENTA UN HALOGENO Y R ES UN ATOMO DE HALOGENO O UN GRUPO ARILO QUE PUEDE ESTAR SUSTITUIDO POR HALOGENO O POR C <- ALQUILO. LA REACCION PUEDE EFECTUARSE EN PRESENCIA DE UN ACEPTOR DE ACIDO, A TEMPERATURAS COMPRENDIDAS ENTRE -20 C Y EL PUNTO DE EBULLICION DE LA MEZCLA DE REACCION. LA PRESION A QUE TIENE LUGAR LA REACCION ES LA ATMOSFERICA, AUNQUE PUEDE EFECTUARSE A OTRAS MAS ELEVADAS O REDUCIDAS.
