Riza, FYI...... Caprolactam = (aminocaproic lactam; 2-oxo-hexamethyleneimine) Properties : White flakes or fused; mp 68-69C; bp 180C (50 mm Hg); d (70% solution) 1.05; refr index 1.4935 (40C); 1.4965 (31C); soluble in water, chlorinated solvents; petroleum distillate; and cyclohexane; heat of fusion 29 cal/g, heat of vaporazion 116 cal/g; viscocity 9 cP at 78C; vap press 3 mm Hg at 100C, 50 mm Hg at 180C. Derivation : 1) Catalytic oxidation of cyclohexane to cyclohexanol, reacting with peracetic acid to form caprolactone, and further reaction with ammonia. 2) Catalytic hydrogenation of fhenol to cyclohexanon, reaction with ammonia to cyclohexanon oxime with beckmann rearrangement with sulfuric acid catalyst. 3) Catalytic oxidation of cyclohexane to cyclohexanon, reaction with hydroxylamine sulfate and ammonia to cyclohexanon oxime followed by sulfuric acid-catalyzed beckmann rearrangement. 4) UV-catalyzed reaction of cyclohexane with nitrosyl chloride to cyclohexanon oxime hydrochloride, followed by beckmann rearrangement. Method (1) was never used commercially. Method (3) has been modified to minimize formation of by-product ammonium sulfate. Forms : Flake, molten. Hazard : Toxic by inhalation. TLV : (vapor) 5 ppm in air, (dust) 1 mg/m3 of air. Use : Manufacture of synthetic fibers (especially nylon 6), plastics, bristles, film, coatings; synthetic leather, plasticizers and paint vehicles, cross-linking agent for polyurethanes, synthesis of amino acid lysine.
