Discussion on the impact of hydration method on caprolactam is welcome
Thread Content
Some people say that the hydration method **affects the quality of the resulting caprolactam, while others believe it has no impact and that the product quality is better than that obtained by the oxidation method. Which statement is correct? Experts are welcome to discuss. Thank you!
You can take a look: http://bbs.hcbbs.com/thread-1236479-1-1.html I’m not sure if the information on page 7 of that post will be useful to you
When the impurities generated by the hydration method are carried on, trace amounts of isomers are formed; these isomers undergo oxime rearrangement and, once they enter the CPL process, may cause yarn breakage in high-speed spinning applications (this is a qualitative observation only).
What is this isomer? Dimethylcyclopentane? Or some other named calibration?
The biggest advantage is environmental protection; don’t draw conclusions based on other factors alone!
