Caprolactam is an important organic chemical raw material, which is widely used in plastics, fibers, adhesives and other fields. This article will detail the properties and uses of caprolactam.

1. Caprolactam Properties

1. Physical Properties
Caprolactam is a white crystalline powder with a high melting point (about 131 ° C) and boiling point (about 270 ° C), insoluble in water, but soluble in hot ethanol, acetone and other organic solvents.

2. chemical properties
caprolactam has high chemical stability, acid, alkali, salt and most of the organic solvent corrosion. At the same time, caprolactam also has good heat resistance and weather resistance.

2. the use of caprolactam

1. Production of nylon
Caprolactam is an important raw material for the production of nylon -6, nylon -6 is an engineering plastic with high strength, toughness, wear resistance and impact resistance, Widely used in automobiles, electronic appliances, aerospace and other fields.

2. Production of fiber
Caprolactam can be used to produce nylon fiber, also known as nylon fiber, which has good elasticity, strength and abrasion resistance, and is commonly used in the production of clothing, ropes, filters, etc.

3. Production of adhesive
Caprolactam can be used as raw material of adhesive, used in the production of hot melt adhesive, pressure sensitive adhesive, etc., with good bonding performance and heat resistance.

4. Other uses
In addition to the above several uses, caprolactam can also be used in the production of epoxy resins, plasticizers and other chemical products.

In conclusion, caprolactam, as an important organic chemical raw material, has broad application prospects in the field of chemical production raw materials.
