zaflab academy of sciences mixed in a flask reagents, demonstrating their new scientific research toom the factory laboratory. water, alcohol, ether, amines, organic acids. it seems that everything is the same as what they do. and exciting. moment: instead of the usual phenol, benzene was taken as a basis, and it gave the desired result. formation of polyamide resin from which fiber can be obtained. the silence of the laboratory was broken by applause. everyone rejoiced at the success, their joint success. the production of coprolactam, thanks to which it became possible to obtain threads and fibers, turned out to be akin to a scientific revolution. in sixty-five has already begun. assimilation of the area under the coprolactam behind the fence, here is the first coprolactam. coprolactam is a derivative of benzene , benzene is a derivative of oil, benzene is isolated from oil as a waste product, by hydrogenating benzene we obtain cycloxane, then we oxidize cyclohexane , we obtain cyclohexane oxim, this cyclohexane is a product of the production of coproloctam at our site, their fiber
