Abstract

PURPOSE: To prepare the titled compound, by the continuous acetoxylation of butadiene in the presence of Pd and Te as catalysts under specific conditions while controlling the concentration of the by-produced furan, etc. in the reaction liquid, and discharging the furan from the system in one pass.
CONSTITUTION: The continuous acetoxylation of butadiene is carried out by passing butadiene, acetic acid and molecular oxygen through a catalyst layer comprising Pd and Te supported on activated charcoal, at 40W120°C and pressure of 30W 100kg/cm2, to obtain diacetoxybutene. The space velocity of the liquid and the O2- containing gas are 0.5W20hr-1 and 5W500hr-1, respectively. The concentrations (ppm) of furan and acrolein, which are by-products of the reaction produced as a result of oxidation of butadiene, in the liquid phase in the catalyst layer, are maintained to satisfy the formula wherein Fi and Ai are concentrations (ppm) of furan and acrolein in the liquid at the inlet of the catalyst layer and fO and AO are concentrations (ppm) of furan and acrolein in the liquid at the outlet of the catalyst layer.
