METHOD FOR THE DOUBLE-BOND ISOMERISATION OF OLEFINS

摘要

The invention relates to a method for producing a C4-C12 olefin (olefin A) from another C4-C12 olefin (olefin B), olefin (A) and olefin (B) differing in terms of the position of the double bond. According to said method, a gaseous mixture containing olefin (B) and between 0.01 and 10 wt. %, in relation to the total quantity of hydrocarbon compounds in said mixture, of a compound having a dipole moment of between 0.5 and 5 Debyes (compound P) is brought into contact with a basic catalyst at a temperature of between 200 and 700 DEG C.
