METHOD OF PRODUCING N-BUTYRALDEHYDE AND/OR N-BUTANOL Russian patent published in 1999 - IPC

FIELD: industrial organic synthesis. SUBSTANCE: 1,3-butadiene interacts with alcohol of formula ROH, wherein R is alkyl or alkenyl with 2-20 carbon atoms optionally substituted by one or two C₁-C₁₀-alkoxy or hydroxy-C₁-C₁₀-alkoxy groups; C₆-C₁₀-aryl; C₇-C₁₁-arylalkyl; or methyl at elevated temperatures and pressure in presence of Broensted acid or Ib, VIIb or VIIIb group element complex with phosphorus- or nitrogen-containing ligands to form adducts corresponding to structures C-C=C-C-OR (II) and C-C(OR)-C=C (III). Adduct III is isomerized into adduct II. The latter is subjected to isomerization in presence of transition metal-containing homogeneous or heterogeneous catalyst in liquid phase or in presence of transition metal-containing heterogeneous catalyst in gas phase to form enol ether with structure C-C- C=C-OR (IV). Enol ether IV is subjected to action of hydrogen and water or only water in presence of homogeneous or heterogeneous catalyst as indicated above to form n-butyraldehyde and/or n-butanol, from which alcohol ROH is further released and recycled into the first step of process. EFFECT: increased selectivity of process and yield of products. 7 cl, 1 dwg, 6 tbl, 15 ex
