The impact of national standard specifications for caprolactam on subsequent production
Thread Content
Hello, I work in the polymerization sector related to caprolactam. I would like to ask: what impact do the various parameters specified in the national standards for caprolactam testing have on subsequent production? The impurities in caprolactam have an impact on production; in which aspect do they have an effect?
I would like to know that too as well; looking forward to advice from experts. . .
By checking its production process, one can basically understand it: toluene is used as a solvent in the synthesis process, and the intermediate products formed include **kuī; then Beckman rearrangement is carried out using concentrated sulfuric acid. A small amount of toluene may not be distilled away, and under the action of concentrated sulfuric acid it forms sulfonic acids, or part of **kuī may be oxidized during Beckman rearrangement to form amorphous carbon. That’s roughly it
