Abstract
Processo per l'isomerizzazione di scheletro di olefine lineari, preferibilmente n-buteni o n-penteni, che consiste nel porre in contatto dette olefine con un catalizzatore formato da allumina sulla cui superficie è depositato ossido di boro in quantità inferiore e 2,1.10-4 g/m2 di superficie dell'allumina.
