Title: Improvements in and relating to methods of preparing cycloalkanone-oximes and lactams in a concentrated acid medium
IPC: C07D201/10
Filed: 1964-08-04
Abstract: A process for the preparation of a cycloalkanone oxime and/or the corresponding lactam, by chemical nitrosation of a cycloalkane consists in subjecting a cycloalkane to the action of nitrosyl chloride in the presence of gaseous hydrochloric acid and a strong acid, insoluble in the reaction medium, comprising sulphuric acid or one of the phosphoric acids, and either isolating the oxime obtained or transforming the oxime obtained into a lactam by means of heating in the presence of a strong acid comprising sulphuric acid or one of the phosphoric acids, wherein the strong acid is recovered in dilute form after separation from the oxime or lactam reaction product and is concentrated, decolorized, and freed from its chlorinated and nitrogenous organic impurities by heating with nitric acid containing 50 to 100% of HNO3, and is then finally re-used in the process. Preferably the strong acid is pretreated with chlorine prior to its concentration after which the chlorinated oils formed are decanted and the acid concentrated. The nitric acid used may be introduced at once or gradually into the acid to be recovered at a temperature of 100-200 DEG  C. and any excess of nitric acid being eliminated and being recovered by distillation.  In an example a solution of cyclododecane and phosphoric acid is saturated with hydrochloric acid gas and nitrosyl chloride added whilst the solution is subjected to radiation from a mercury vapour lamp and a stream of hydrochloride gas still passed in. The resulting phosphoric layer containing cyclododecanone oxime is decanted and the cyclododecanone oxime is precipitated and purified. Into the dilute phosphoric acid recovered from the drying of the first portion of oxime a slow current of chlorine is passed.  The oily products formed are separated by filtration and concentrated. The coloration of the phosphoric acid is 8 on the Gardner scale. 5 grams of 95% nitric acid is added, heating is gradually effected to 200 DEG  C. under reflux.  The excess nitric acid is eliminated at 200 DEG  C. under a vacuum of 2 mm. of mercury. The coloration of the phosphoric acid thus obtained is 2 on the Gardner scale.  In another example the phosphoric solution of cyclododecanone oxime prepared as above is heated for an hour and the reaction mixture diluted when the dodecanolactam is precipitated and the precipitate extracted with chloroform and the aqueous phosphoric layer decanted from the chloroform layer of the lactam is concentrated at 200 DEG  C. under vacuum until a concentration of 103% of H3PO4 is obtained, this acid being black in colour. 95% nitric acid is added, the mixture is gradually heated under reflux to a temperature of 200 DEG  C. and maintained for 6 hours when the excess of nitric acid is distilled under a vacuum of 2 mm. of mercury.  The phosphoric acid thus obtained is practically colourless.
