Chloropropene discoloration issue? ?
Thread Content
Chloropropene products often change color. What could be the reason? Solution?
If you use glassware, it won’t change color, because chloroprene tends to extract rubber and plastic additives or paint from other types of containers
The material, oh, I haven’t paid attention to that yet. I’ll look into it and we can discuss the details later. The process involves producing crude chloropropene through high-temperature chlorination; after removing propylene and hydrogen chloride gases, it is sent to a distillation tower for separation of light and heavy components, resulting in a product with a purity of 98.5%. This product often changes color in summer. According to technical analysts, this is due to the organic polymerization of chloropropene
What kind of production team are you in? It seems you’re very knowledgeable about ALC; feel free to ask me questions if you have any
The technical staff seem to be working on this issue; there has been some progress, but according to the factory’s meeting minutes, it seems that no solution has yet been found. How can I get in touch with you to discuss this? Maybe I can invite you to serve as a production consultant when I become the boss. Hahaha. Thank you very much for your response; your analysis seems quite accurate. That grass-green substance… I think I saw it during the maintenance of our distillation tower; it was stuck on the trays
What’s your QQ? And where do you work?
What you are seeing are hydrated crystals of ferrous chloride resulting from a leak in the heat exchanger; it is not caused by the polymerization of high-boiling substances. They are complexes of trivalent iron ions, which are unstable
