Propylene hydration catalyst
Resistant high-temperature
Making IPA by propylene hydration
High functional group stability
Propylene hydration resistant high-temperature catalyst DHC-1
DHC-1 propylene hydration catalyst is a kind of macroporous crosslinked polynlene strong acid cation resin. It can resistant high-temperature, the maximum temperature is 180°C. DHC-1 can be used for long time under 130~180°C.
DHC-1 thermostable catalyst is specially used in the propylene hydration reaction, with good activity and selectivity. Superior mechanical strength also with high stability of functional groups.
