Reaction Conditions

Reaction Steps

In a reaction vessel was placed 8100 parts of phenol and 27 parts of aluminum metal. The vessel was sealed and heated to 150° C. to form aluminum triphenoxide. This catalyst concentrate was then mixed with 11,124 parts of additional phenol. This gives a phenol/aluminum mole ratio of about 203. The phenol-catalyst mixture was cooled to 90° C. and 23,490 parts of isobutylene was pumped in over a 50-minute period. The reaction temperature rose to 110° during the first 10 minutes of isobutylene feed. Stirring was continued at 110°-115° C. for 165 minutes. Reactor pressure dropped to 120 psig from a maximum of 260 psig.
