Title:
PROCESS FOR PREPARING MALEIC ANHYDRIDE FROM C4 HYDROCARBON
Document Type and Number:
Japanese Patent JPS53124216
Kind Code:
A
Abstract:
Vanadium-free catalysts consisting essentially of oxides of titanium and phosphorus have been found to be especially effective in the oxidation of n-butane, n-butenes and 1,3-butadiene with molecular oxygen in the vapor phase to yield maleic anhydride. The reaction with n-butane gives an especially pure product in good yield and selectivity.
