Reaction Conditions

Reaction Steps

A reaction tube having an inner diameter of about 12 mm (sectional area, 1.005 cm2) was packed with 4 g of a catalyst and maintained at 6 MPa and 80° C. Butadiene, acetic acid, and nitrogen gas containing 6 mol % oxygen were continuously introduced upward into the reaction tube from its bottom at rates of 0.15 mol/hr, 2.5 mol/hr, and 100 NL/hr, respectively, to yield diacetoxybutene. A reaction liquid obtained in the period from 4 hours after initiation of the reaction to 5 hours after the initiation and a reaction liquid obtained in the period from 6 hours after the initiation to 7 hours after the initiation were analyzed by gas chromatography. The rate of consumption (mmol/hr) of the butadiene per kg of the catalyst was calculated from the average of those found values and taken as catalytic activity. The results obtained are shown in Table 1.
