Thiopropionic acid
Thread Content
Experts, please offer some advice. We produce thiopropionic acid, and choosing a pump for the hydrolysis solution is always a challenging task. Components of the hydrolyzate: salts, acids, cyanoacrylate, etc.; there are trace amounts of small particles. Temperature: 120°C; density: 1.15; head pressure: 20 m; flow rate: 10 m3/h; cavitation threshold: 0.5. Due to the presence of **strong acids, leaks must be avoided at high temperatures; I seek advice from experts
Fluoroplastic pumps should work fine. We have used mercaptans before, but back then we employed nitrogen pressure and vacuum drawing methods; only a pump was used for the final filtering step
I think using a pump with an enhanced polypropylene plastic lining will suffice; polytetrafluoroethylene would of course be better
Polypropylene is likely not suitable at a temperature of 120 degrees; I think a pump made of PTFE would be necessary.
I know someone who has the skills for this; maybe he can help you. 275494406
