epsilon-Caprolactam

카프로락탐 C화학적 특성, 용도, 생산

개요

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.

화학적 성질

Caprolactum is a white crystalline combustible solid with an unpleasant odor. The Odor Threshold is 0.3 milligram per cubic meter.

물리적 성질

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.

용도

Monomer for manufacture of polycaprolactam (Nylon 6) used in carpets, textiles, clothing, and tires

제조 방법

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.

정의

ChEBI: A member of the class of caprolactams that is azepane substituted by an oxo group at position 2.

일반 설명

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.

공기와 물의 반응

Water soluble.

반응 프로필

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.

위험도

Toxic by inhalation. Upper respiratory tract irritant.

건강위험

Inhalation causes coughing or mild irritation. Contact with hot liquid will burn eyes and skin.

화재위험

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

잠재적 노출

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.

운송 방법

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

비 호환성

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

폐기물 처리

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
