Purolite® CT275
Macroporous Strong Acid Resin
Catalyst
The wet Purolite CT275 catalyst
is a macroporous, strongly acidic, polymeric
catalyst. Its unique properties include
higher acid strength, higher total acid
sites and higher thermal stability. The
catalyst also has a unique structure with
properties that include a large pore diameter
and volume allowing reactants access to
those active acid sites. Because of its
larger pore structure, it has a greater
resistance to fouling due to the formation
of polymeric side products. In addition,
it has lower shrinking and swelling properties.
Purolite CT275 has been developed to catalyze
many organic reactions including oxygenates
such as ETBE, MTBE and TAME and silicon-based
polymer chemistry.
