Caprolactam Chemical Properties,Uses,Production
Description
Caprolactam, CH2CH2CH2CH2CH2NHCO, is a solid material composed of white flakes. Caprolactam is soluble in water and has a specific gravity (in a 70% solution)of 1.05, which is heavier than water. It may also be encountered as a molten material. Caprolactam is toxic by inhalation, with a TLV of (vapor) 5 ppm in air and (dust) 1 mg/m3 of air. The primary uses are in the manufacture of synthetic fibers, plastics, film, coatings, and polyurethanes.
Chemical Properties
Caprolactum is a white crystalline combustible solid with an unpleasant odor. The Odor Threshold is 0.3 milligram per cubic meter.
Physical properties
Yellowish solid or white crystals or flakes; amine, spicy aroma. It is soluble in water, chlorinated solvents, petroleum hydrocarbons, cyclohexene, benzene, methanol, ethanol and ether.
Uses
Monomer for manufacture of polycaprolactam (Nylon 6) used in carpets, textiles, clothing, and tires
Preparation
About 90% of the caprolactam is produced by the conventional cyclohexanone process. Cyclohexanone is obtained by catalytic oxidation of cyclohexane with air? or by hydrogenation of phenol and dehydrogenation of the cyclohexanol byproduct. The conversion of cyclohexanone to cyclohexanone oxime followed by Beckmann rearrangement gives caprolactam. About 10% of caprolactam is produced by photonitrosation of cyclohexane or by nitrosation of cyclohexanecarboxylic acid in the presence of sulfuric acid.
Definition
ChEBI: A member of the class of caprolactams that is azepane substituted by an oxo group at position 2.
General Description
Clear to milky white-colored solution with a mild, disagreeable odor. Contact may cause slight irritation to skin, eyes, and mucous membranes. May be mildly toxic by ingestion. The primary hazard is the threat to the environment. Immediate steps should be taken to limit its spread to the environment. As a liquid 2-Oxohexamethylenimine can easily penetrate the soil and contaminate groundwater and nearby streams. Used to make other chemicals.
Air & Water Reactions
Water soluble.
Reactivity Profile
2-Oxohexamethylenimine is hygroscopic. 2-Oxohexamethylenimine can react with strong oxidizing agents and strong bases. 2-Oxohexamethylenimine can also react with chlorinated hydrocarbons and nitro compounds. A potentially explosive reaction occurs with acetic acid + dinitrogen trioxide.
Hazard
Toxic by inhalation. Upper respiratory tract irritant.
Health Hazard
Inhalation causes coughing or mild irritation. Contact with hot liquid will burn eyes and skin.
Fire Hazard
Special Hazards of Combustion Products: Toxic oxides of nitrogen
Safety Profile
Moderately toxic by ingestion, skin contact, intraperitoneal, and subcutaneous routes. Human systemic effects by inhalation: nose and throat irritation, cough. Experimental reproductive effects. A skin and eye irritant. Potentially explosive reaction with acetic acid + dinitrogen trioxide. When heated to decomposition it emits toxic fumes of NOx
Potential Exposure
Caprolactam is used in the manufacture of nylon, plastics, bristles, film, coatings, synthetic leather, plasticizers, and paint vehicles; as a crossslinking agent for curing polyurethanes; and in the synthesis of lysine
Carcinogenicity
Caprolactam was not mutagenic in bacterial assays or in in vivo rodent assays; it did induce chromosomal aberrations and aneuploidy in human lymphocytes in vitro.
Shipping
UN2811 Toxic solids, organic, n.o.s., Hazard Class: 6.1; Labels: 6.1-Poisonous materials, Technical Name Required
Purification Methods
The lactam is distilled under reduced pressure, recrystallised from acetone or pet ether and redistilled. It can be pur
Incompatibilities
Caprolactum decomposes on heating, and on burning producing toxic fumes including nitrogen oxides, ammonia. Reacts violently with strong oxidizers, producing toxic fumes. Toxic decomposition above 400C
Waste Disposal
Controlled incineration (oxides of nitrogen are removed from the effluent gas by scrubbers and/or thermal devices). Also, Caprolactam may be recovered from Caprolactam still bottoms or nylon waste
