ABSTRACT
This chapter continues the discussion of the use of solid reagents to minimize exposure to hazardous reagents, to make workups easier, and to minimize waste. Liquid acids are also corrosive, may be dif cult to recycle for repeated use, and may show low activity or selectivity in some reactions.1 Large amounts of sulfuric acid and hydrogen uoride are used in petroleum re ning for the alkylation of isobutene with ole ns to produce high-octane gasoline.2 A typical reaction of this type (6.1 Schematic) is shown.
