Process for the esterification of isobutene |
| abstract |
A process for the esterification of isobutene with reduced polymerization of the isobutene which comprises contacting the isobutene with a lower carboxylic acid and an acidic resin catalyst containing a sulfonate group, which catalyst has between about 0.2 and 2.4 meq. of H+ per gram of catalyst. Preferred carboxylic acids include formic acid and acetic acid and the preferred type catalyst is a resinous sulfonated polystyrene divinyl benzene copolymer. |
