Popis: A statistical design method for multiresponse models was used in an experimental study of a reaction network. The study involved the vanadia-catalysed oxidation of o-xylene using a recirculation reactor. Concentrations of reactants and temperature were used as operating variables, and the concentrations of products were the measured responses. The published design procedure was modified by conducting several runs after each design evaluation to reduce computing costs while retaining the benefits of statistical design and analysis. This enabled network analysis to be conducted efficiently to the limits of the equipment, and pointed the way to improved estimates of the parameters. On a employe une methode de concept statistique pour des modeles a reponses multiples en faisant une etude experimentale d'un reseau de reactions. L'etude impliqua l'oxydation de l'ortho-xylene en utilisant l'oxyde de vanadium comme catalyseur et un reacteur a recirculation. Les concentrations des reactifs et la temperature ont servi de variables operatoires et les concentrations des produits ont ete les reponses mesurees. On a modifie le procede de conception publie anterieurement en executant plusieurs experiences, apres chaque evaluation de la conception, pour diminuer les coǔts des calculs, tout en conservant les benefices du concept et de l'analyse du reseau d'une maniere aussi efficace que l'outillage le permettait et paver le chemin pour faire le meilleures evaluations des parametres.
