A process is provided for the skeletal isomerization of straight chain olefins to branched chain olefins wherein the olefin is contacted with an activated alumina catalyst which has a particle size of from about 0.5.times.10.sup.-3 cm to about 160.times.10.sup.-3 cm and at least 10% of the pore volume is attributable to pores having radii between about 100 and 10,000 Angstroms.

Isomerization

A process is provided for the skeletal isomerization of straight chain olefins to branched chain olefins by contact at an elevated temperature with a chlorine- or fluorine-containing compound activated alumina catalyst, the alumina having an average particle size of from about 0.5.times.10.sup.-3 cm to about 160.times.10.sup.-3 cm and from 3 to 9% of the pore volume being attributable to pores having radii from about 100 to about 10,000 Angstroms.

Disclosed is a method of removing iodine-containing compounds from the reaction product of iodine-catalyzed acetoxylation, wherein an olefin is reacted with oxygen and a carboxylic acid, and the iodine is recycled to the reactor.

Catalyst recovery process

Epoxy compounds are produced by the vapor phase deacyloxylation of vicinal hydroxyesters in the presence of a basic material. The co-product carboxylic acid may be reacted with olefins to form additional hydroxyesters.
