description Process for obtaining 2,4-dichlorophenoxyacetic acid (2,4- D) in the dry phase. Process for obtaining esters of 2,4-dichlorophenoxyacetic acid (2,4-D) in the dry phase corresponding to the following general structural formula where R can be a straight or branched alkyl or alkenyl group or an acrylic group. Comprises the development of a new highly selective method for obtaining esters derived from 2,4-D acid operating in the dry phase through the use of commonly used preferably porous substrates of the oxides type such as silicas and aluminas, or of the silicates type such as zeolites, and bentonites, sepiolites and other clay minerals which are in any event used in the form of powders or finely divided solids. Can be used to directly obtain a semiformulated solid as a herbicide. PROCEDIMIENTO DE OBTENCION EN FASE SECA DE ESTERES DEL ACIDO 2,4-DICLOROFENOXIACETICO (2,4-D). PROCEDIMIENTO DE OBTENCION EN FASE SECA DE ESTERES DEL ACIDO 2,4-DICLOROFENOXIACETICO (2,4-D), QUE CORRESPONDEN A LA SIGUIENTE FORMULA ESTRUCTURAL GENERAL. C6H3CL2-O-CH2-COOR DONDE R PUEDE SER UN GRUPO ALQUILICO O ALQUENILICO LINEALES O RAMIFICADOS, O INCLUSO UN GRUPO ARILICO. CONSISTE EN EL DESARROLLO DE UN NUEVO METODO ALTAMENTE SELECTIVO DE OBTENCION DE LOS ESTERES DERIVADOS DEL ACIDO 2,4-D OPERANDO EN FASE SECA CON EL EMPLEO DE SOPORTES PREFERENTEMENTE POROSOS DE USO COMUN DEL TIPO DE OXIDOS COMO SON SILICES Y ALUMINAS, O DEL TIPO DE LOS SILICATOS COMO SON LAS ZEOLITAS, ASI COMO BENTONITAS, SEPIOLITAS Y OTROS MINERALES DE LA ARCILLA Y EN CUALQUIER CASO UTILIZADOS EN FORMA DE POLVOS O SOLIDOS FINAMENTE DIVIDIDOS. PERMITE OBTENER DIRECTAMENTE UN SOLIDO SEMIFORMULADO, COMO HERBICIDA.
