Process for the preparation of alkylfurans

A process for the preparation of alkylfurans comprising reacting furan with an alkene in the presence of a supported phosphoric acid catalyst wherein the alkene has from 4 to 20 carbon atoms and is a branched chain alkene which is a 1,1-disubstituted ethene or a tri- or tetra-substituted ethene and...

description	A process for the preparation of alkylfurans comprising reacting furan with an alkene in the presence of a supported phosphoric acid catalyst wherein the alkene has from 4 to 20 carbon atoms and is a branched chain alkene which is a 1,1-disubstituted ethene or a tri- or tetra-substituted ethene and the molar ratio of furan to alkene is at least 1:1. The catalyst is supported on a silica-containing support which is preferably manufactured silica or a naturally occurring silicaceous composition e.g. kieselguhr. The alkylfurans may be used as a gasoline additive.
