METHOD OF SYNTHESIS OF THE MIXTURE OF TRANS-3,4- AND TRANS-3,5-DIACETOXYCYCLOPENTENES Russian patent published in 1996 - IPC

Abstract SU 1829335 A1

FIELD: chemical technology, acetoxylation of conjugated dienes. SUBSTANCE: 1,3-cyclopentadiene is acetoxylated using acetic acid and air oxygen in the presence of intermetallic catalyst Rh2Te applied on the activated carbon at concentration 2.8-3.6 wt.-%, and carrier - the rest. Process is carried out at 80-85 C, under pressure 8.5-9.0 MPa with addition of sodium chloride to the raw at concentration 0.01-0.02% of catalyst mass. The yield is 94-96%. EFFECT: improved method of synthesis, increased yield of product. 4 tbl
