Question regarding the purity of dimethyl silicone through distillation
Thread Content
I would like to ask questions regarding the silicone industry within the polysilicon community: To what degree of purity can the dimethyl monomer used in silicone production be achieved through distillation? Are there manufacturers with 99.95% accuracy?
Yes, it exists in Zhangjiagang, Jiangsu.
Could everyone please share some more experience on how to improve it to 99.95%?
How to improve? Use your own brainpower; hardware is the first step
We still need everyone’s strong support! Are you referring to improving the tray? I was wondering if any institution has specifically analyzed what substances make up that remaining 0.1% of impurities? There is still room for improvement in terms of operation; we have been maintaining a level around 99.98 for a long time, and it’s not possible to reach 99.9%!!! Those with experience, please help us out! Thank you to the Haichuan platform for providing this opportunity for communication!
Dimethyl distillation can maintain 99.9%, but higher levels cannot be stabilized
You mean Zijiang Sidao Corning, right? Hehe, they are experienced professionals
Three 9s and one 5 should work. 4 nines are basically unattainable in China
