Abstract: A process provided for separating an Alpha -amino- omega lactam of the formula:

WHEREIN N IS AN INTEGER FROM 0 TO 12, IN ITS FREE FORM FROM THE REARRANGED MIXTURE OBTAINED BY THE Beckmann rearrangement of an Alpha -aminocycloalkanone oxime of the formula:

WHEREIN N IS AN INTEGER FROM 0 TO 12, WHICH PROCESS COMPRISES THE STEPS OF: CONTACTING THE REARRANGED MIXTURE WITH A SOLVENT SELECTED FROM THE GROUP CONSISTING OF: A. LINEAR AND CYCLIC ETHERS AND POLYETHERS, B. C3 to C8 alcohols in the absence of chloride ions, C. NITRILES CONTAINING TWO OR MORE CARBON ATOMS, D. AROMATICS AND HALOAROMATICS IN THE PRESENCE OF AT LEAST ONE OF SAID (A) OR (B), WHEREIN THE HALO SUBSTITUENT IS CHLORINE OR BROMINE AND IS ATTACHED DIRECTLY TO THE RING, E. CHLOROFORM, F. TRICHLOROETHYLENE IN THE PRESENCE OF AT LEAST ONE OF SAID (A) OR (B), AND G. MIXTURES OF TWO OR MORE OF THE ABOVE, WHILE SIMULTANEOUSLY NEUTRALIZING THE RESULTANT SOLUTION WITH AN EXCESS OF ANHYDROUS AMMONIA BASED ON THE HYDROGEN ION CONCENTRATION IN THE SOLUTION, WHEREBY AN INSOLUBLE AMMONIUM SALT PRECIPITATE IS FORMED; AND SEPARATING A SOLUTION CONTAINING AN Alpha -AMINO- omega -LACTAM IN ITS FREE FORM FROM THE PRECIPITATE.

Abstract: This invention relates to an improved method of separating haloalkanes from alkanes or other haloalkanes of lower halogen to carbon ratio by extraction with dialkyl sulfoxides, cyclic lactams or nitroparaffins. The haloalkanes of interest are fluoroalkanes, chloroalkanes, and bromoalkanes.

Abstract: 2-Aminocycloalkanone oximes are produced by reacting, in an oxygen-free environment, hydroxylamine phosphate or hydroxylamine sulfate with anhydrous ammonia; removing the precipitated ammonium salt; adding ammonium chloride to the solution; maintaining the solution within a preselected temperature range while adding 2-chlorocycloalkanone; maintaining the desired temperature until the reaction is complete and isolating the oxime product.

Abstract: Polycondensation of monomer of the structure:

WHEREIN R is H or a C1-C6 alkyl group, wherein X is an alkyl radical of up to four carbons, chlorine or bromine, and n is O-4, affords polymers having recutting units of the structure:

These polymers have good thermal stability and transparency and a high, but not unduly high, glass transition temperature.

Abstract: Alpha -amino- delta -valerolactam and Alpha -amino- Epsilon caprolactam are produced by contacting the corresponding Alpha aminocycloalkanone oxime or mineral acid salt thereof with liquid SO2 containing at least about 1 mole SO3 per mole Alpha aminocycloalkanone oxime until a two-phase system comprising a liquid SO2 phase and an insoluble lactam precursor phase is formed; separating the liquid SO2 phase from the insoluble phase containing the lactam precursor; hydrolyzing and neutralizing the insoluble lactam precursor phase and recovering the free lactam product.

Abstract: Lysine is produced by a process comprising the steps of 1. Nitrating cyclohexanone to form 2-nitrocyclohexanone; 2. Nitrosating the 2-nitrocyclohexanone to form 2-nitro-6oximinocyclohexanone; 3. Ring opening the 2-nitro-6-oximinocyclohexanone in alcoholic base to form an ester of 2-oximino-6-nitrocaproic acid; 4. Hydrogenating the 2-oximino-6-nitro caproic acid alkyl ester to form an alkyl ester of lysine; and 5. Saponifying the lysine alkyl ester to afford lysine or a salt thereof.
