  • Process for the purification of caprolactam by means of ozone
    Patent number: 4178287
    Abstract: There is described a process for the purification of caprolactam from the idable impurities present therein, by means of a treatment with an oxidizing agent consisting of ozone, the process comprising the steps of dissolving the polluted caprolactam into a solvent inert to ozone, such as water, and of causing the ozone to bubble through the resulting solution, the concentration of the caprolactam in the solution being preferably comprised between about 40% and 78% by weight of caprolactam, and the treatment being preferably effected at a temperature between the freezing temperature of the solution and 70.degree. C.
