Purolite®
CT169DR
Macroporous Strong Acid
Resin Catalyst
Purolite CT169DR is a superior
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 CT169DR.
It is supplied dried to less than 3% moisture.
Alternatively it can be supplied completely
water-swollen as Purolite CT169. Its superior
mechanical strength makes Purolite CT169DR
especially suitable for use in fluidised
systems where mechanical resistance of
the catalysis resin is a very important
characteristic. Purolite CT169 may be
used for various catalysis application,
including tertiary alkyl methyl ether
(TAME) in particular, methyl tertiary
butyl ether (MTBE).
