Abstract
SE REIVINDICA UN PROCESO PARA PURIFICAR UNA CORRIENTE GASEOSA INERTE MEDIANTE UNA REACCION DE TRANSESTERIFICACION EN LA CUAL SE LIBERA UN ALCOHOL ALQUILICO DE CADENA CORTA DURANTE EL TRANSCURSO DE LA REACCION. UN SEGUNDO USO DEL PROCESO ES LA FABRICACION DE ESTERES ALQUILICOS DE CADENA CORTA, POR EJEMPLO METILICOS, DE ACIDOS GRASOS MEDIANTE UNA REACCION DE TRANSESTERIFICACION UTILIZANDO LOS ALCOHOLES GASEOSOS COMO FUENTE DE LOS ALCOHOLES ALQUILICOS DE CADENA CORTA. EL ALCOHOL SE DILUYE CON NITROGENO U OTRO GAS PORTADOR INERTE Y SE HACE REACCIONAR CON UN ESTER DE ACIDO GRASO, PREFERIBLEMENTE UN TRIGLICERIDO, PARA FORMAR EL CORRESPONDIENTE ESTER METILICO O ALQUILICO DE CADENA CORTA DEL ACIDO GRASO.
