| titleOfInvention | Production of epsilon-caprolactam and o-acetylcyclohexanoneoxime' |
| abstract | 1357627 #-Caprolactam and O-acetylcyclohexanoneoxime KANEGAFUCHI BOSEKI KK 20 Dec 1971 [22 Dec 1970] 59199/71 Heading C2C s - Caprolactam and O - acetylcyclohexanoneoxime are produced by reacting together cyclohexanoneoxime and N-acetylcaprolactam in the presence of an acid. Preferred acids are inorganic acids, e.g. H 2 SO 4 , HNO 3 , HCl, HF, H 3 PO 4 , H 4 P 2 O 7 , HClO 4 , HBF 4 ; carboxylic acids, e.g. formic, acetic, propionic, butyric, valeric, caproic, oxalic, succinic, glutaric, adipic, benzoic, mono-, di- and trichloracetic and trifluoracetic acids; sulphonic acids, e.g. benzenesulphonic and toluenesulphonic acids; acid ion-exchange resins; and Lewis acids, e.g. BF 3 , AlCl 3 , ZnCl 2 and NiCl 2 . The amount of acid used is generally 0À01 to 200% based on the total weight of reactants and the process may be conducted at 0-120 C. in the presence of an organic solvent that is inert to the reagents used. 0À01 to 80 Mols. of cyclohexanoneoxime is normally used per mol. of N-acetylcaprolactam. Reference has been directed by the Comptroller to Specification 1,315,607. |
