The reasons for **sulfonic acid redening
Thread Content
A batch of material produced in the workshop was divided and crystallized in two crystallization vessels; as a result, the material that crystallized in one vessel turned red, while it crystallized normally in the other vessel. Which brother knows what the reason is? Is it caused by that substance? We put a portion of clean water in the crystallization tank in advance. This post was last edited by hwqckr on 2009-3-6 17:58.]
The original poster didn’t clarify into which pot your pure water should be poured; it’s likely that there are impurities in the pot, or that the color of the crystalline hydrate is red.
At first, we also suspected it to be rust, but the sulfonation material from our same reactor goes through the same pipeline into two crystallization vessels; there is no reason for one of them to turn red while the other does not.
If it’s rust, can we use a filter to remove it? What kind of filter should be used? Our liquid material has a temperature of 110°C and is highly acidic.
