Abstract

Various sulfated solid catalysts were prepared and tested for etherification of certain C6 olefins with methanol. Their catalytic activities were compared with the results obtained using some typical commercial ion-exchange resin catalysts. The commercial resin catalyst Amberlyst 15 showed nonselective conversion to ether, with significant accompanying isomerization, while Nation and silica supported Nation exhibited lower activities. Sulfated silica and montmorillonite showed comparable and sometimes higher ether yields than the commercial resin catalysts. Catalyst preparation variables influencing the catalytic activity of the sulfated silica were investigated with the objective of increasing ether yields.
