TA2 can it withstand a benzene solvent containing 30% hydrochloric acid, with no water present?
Thread Content
I would like to ask everyone: the solution is a benzene solution containing 30% hydrochloric acid, and the material of the flow-through components is TA2. I wonder whether it can resist corrosion
What device is it? If it is a heat exchanger, a graphite heat exchanger is recommended. Graphite heat exchangers can be used for a long time at the boiling point of hydrochloric acid at any concentration without experiencing corrosion.
The Super Shield polymer coating based on US IPN technology can be used. www.dlsunny.com
It’s possible in theory. Since the hydrogen chloride in benzene solution is a non-aqueous solution that does not ionize, its corrosivity is virtually none.
My question is whether, in devices that are not completely airtight, ionization can occur with the moisture in the air
We know that titanium and titanium alloys are not resistant to corrosion by relatively pure reducing acids (sulfuric acid, hydrochloric acid); therefore, they are generally not used under such conditions as corrosion and damage may occur.
Is it the heat exchange part or the pipeline? Pipes: steel-lined with PTFE or glass; for heat exchangers, silicon carbide high-efficiency heat exchangers can be used – they have a high thermal conductivity, are resistant to corrosion, can withstand temperatures up to 260 degrees, do not corrode in areas subject to flow, and allow for clean use as well as recycling!
