Abstract

1,198,427. Production of lactams. BP CHEMICALS (U.K.) Ltd. 15 May, 1968 [6 June, 1967], No. 26076/67. Heading C2C. Lactams are produced by heating a solution of a compound of formula wherein X and X<SP>1</SP> are divalent aliphatic radicals which may be the same or different, in a non-hydrocarbon organic solvent containing a salt of an element of Group I or II. The examples prepare caprolactam with cyclohexanone and caproamide formed as byproducts.
