Purolite® CT269DR
Macroporous Strong Acid Resin
Catalyst
Purolite CT269DR is a superior,
high capacity, macroporous strong-acid catalyst
resin which has recently been developed
from poly(vinylbenzenesulfonate) cation
exchangers. While ordinary commercial styrene-based
sulphonic acid resins may often be used
for chemical reactions catalysed by the
H+ ion, faster process times, better yields
and higher product purity may be obtained
by using a properly designed and purified
catalyst resin such as Purolite CT269DR.
It is supplied dried to less than 3% moisture.
Alternatively it can be supplied completely
water-swollen as Purolite CT269. Its superior
mechanical strength makes Purolite CT269DR
especially suitable for use in fluidized
systems where mechanical resistance of the
catalysis resin is a very important characteristic.
Purolite CT269 may be used for various catalysis
application, including tertiary alkyl methyl
ether (TAME) in particular, methyl tertiary
butyl ether (MTBE).
