Caprolactam: A name:

Caprolactam is the abbreviation of ε - caprolactam, whose molecular formula is c6h11no. It is synthesized by cyclohexanone hydroxylamine (now referred to as oxime method), abbreviated as CPL.

B appearance:

The solid appearance is white and flake solid without visible mechanical impurities; the liquid appearance is colorless and transparent liquid without visible mechanical impurities.

C shape:

The solid state is white (flake), and the liquid is colorless and transparent liquid.

D features:

Caprolactam is colorless in liquid state and white (flake) in solid state. It has lubricating feeling and special smell when touching by hand. It is hygroscopic, soluble in water and benzene, etc. when heated, caprolactam starts polymerization reaction and can burn in case of fire. The melting point is 68 ℃ - 69 ℃, the boiling point is 270 ℃ at 760mmhg, and the density is 1010kg / m3 at 85 ℃.

E marking, packaging, storage and transportation:

Mark -- caprolactam for industrial use should have the following marks: trademark, name of manufacturer, address, standard number, product name, production date, batch number and net content, etc.

Packaging - solid caprolactam is packed in double bags. The inner bag is polyethylene film bag, which is heat sealed; the outer bag is polyethylene three in one bag, selected according to GB / t8947, and sealed by mechanical sewing. The net content of each bag is (25 ± 0.25) kg.

Storage and transportation -- Industrial caprolactam should be protected from dampness and sunlight during transportation, and packaging bags should be prevented from damage. It shall be stored in dry and clean warehouse and shall not be stored in the open air or affected by damp. It should be isolated from heat source and fire, and should not be stored and transported together with deliquescent articles, oxidants, acids and alkalis. Handle with care to prevent damage to packaging. The shelf life is 3 months under the conditions of storage and transportation. The product can be retested after the shelf life. If the test results meet the requirements of this standard, the product can still be used.

F purpose:

It is mainly used to produce polyamide-6 (nylon 6). Polyamide-6 can be processed as follows: Civil silk can be used to make civil spinning products, such as clothing, ornaments, carpet, blanket, etc.; industrial yarn can be used to make tire cord fabric, canvas, transport belt, fishing net, rope, landing surface, etc.; engineering plastics can be used to make parts and components of machinery, automobile, electrical appliances, electronic products, engineering pipes, bars, plates and strips.
