    Railroad tank cars are used for more than just transporting fuels; they also transport all kinds of chemicals for industrial use: One chemical that requires specially insulated tank cars capable of being heated is caprolactam - a starting material for the plastics industry – more precisely for the ring-opening polymerization of polyamide 6 (perlon). Another possibility for the polymerization process is in the hydrolytic splitting of the amide bond and the condensation polymerization that then follows. Several mega-tons of polyamide 6 are produced each year. Cyclohexanoxime is produced from cyclohexanone for this purpose by a conversion process with the hydrogen sulfate or the hydrochloride of the hydroxylamine. This is then transformed into caprolactam with a Beckmann rearrangement process. Usually, concentrated sulfuric acid is used as a catalyst. caprolactam forms white crystals at room temperature that are soluble in water and that have hygroscopic properties. Caprolactam is therefore usually stored at temperatures over 80° C or 176° F and is transported by rail as in our example. In the presence of greater heat caprolactam breaks down under the formation of ammonia and nitrogen oxides; the elaborate technology for transport therefore requires special, modern tank cars.
