Failure of catalytic resin
Thread Content
As the title suggests, it’s an esterification catalyst made of strongly acidic resin, used in industrial applications; it loses its effectiveness within less than half a month. However, there is no significant decrease in its ion exchange capacity. Why is that? There are two possible reasons for this, as analyzed individually: one is channeling in the reactor, but since the flow velocity inside the reactor is not high, this possibility seems low Another possibility is that the pores of the resin are blocked or its active surface is covered, but the hydrogen form does not convert into a salt. How should we view this situation? If it is the latter possibility, how can it be detected and confirmed?
Did the temperature rise abnormally during use?
It’s not a fly-temperature reaction; it’s a fully liquid-phase reaction.
