F. Avramescu, EQUIMOLECULAR COMPOSITION P2O5-SIO2 CATAL YST ACTIVITY IN THE 4-4'-DIMETHYL-1,3-METADIOXANE DECOMPOSITION REACTION TO ISOPRENE .4., Revista de chimie, 45(6), 1994, pp. 455-458
The activity of P2O5 - SiO2 catalyst by equimolecular composition, P2O
5/SiO2 = 1,0 molar ratio, activated by calcination at 800-degrees-C fo
r 10 hours, was presented as function of operation parameters, in the
decomposition reaction of 4,4'-dimethyl-1,3-dioxane to isoprene. In th
e established reaction conditions the yield of isoprene is 82.5% moles
and the selectivity 84% moles.
