Process for the preparation of lauryllactam by photonitrosation of cyclododecane and Beckmann rearrangement in the presence of methanesulphonic acid

摘要

To the present invention:; a - it was also a cycloalkyl dissolved in an organic solvent, the reaction decane, nitrating agent and hydrogen chloride in the presence of an acid to form an oxime-cyclo dodecyl canon,; b - Only Beckman of the above oxime in the presence of an acid gaze will grow Nirvana; In the process for producing a la-lactam us configured, the acid relates to a method of producing la lauryl lactam, characterized in that methanesulfonic acid.
