METHOD OF PRODUCING DIACETOXYBUTENES Russian patent published in 1999 - IPC

FIELD: industrial organic synthesis. SUBSTANCE: method involves liquid-phase acetoxylation of 1,3-butadiene carried out at 70-90 C and pressure 7.0-10.0 Mpa in presence of catalyst containing activated carbon carrier and active ingredient including palladium or tellurium, thallium, gallium, germanium, rhodium or tungsten and constituting intermetallide with general formula Pd₄Te₂M₃ or Rh₂TeM, wherein M is thallium, gallium, or germanium and content of intermetallide is 4.5 to 5.8 wt %, or intermetallide with general formula Pd₄Te₃W₂ or Rh₄Te₃W, contents of the latter being 3.4 to 5.2 wt %. Process is carried out by adding peracetic acid to reaction mixture in amounts from 5.0 to 30.0% of intermetallide weight. Productivity of process is 1.87 to 2.0 g per 1 l of catalyst in 1 hr. EFFECT: increased productivity of process. 2 tbl
