⚗️ Chemical & Physical Properties
Caprolactam is a white crystalline solid with a faint odor. It is typically in the form of small beads or flakes.
The molar mass of Caprolactam is approximately 113.16 g/mol, with a density of 1.01 g/cm³. This places it in the range of common household items such as table salt (molar mass of 58.44 g/mol, density of 2.16 g/cm³).
Caprolactam has a melting point of 69.85°C and a boiling point of 271.50°C. These values are similar to those of water (melting point of 0°C, boiling point of 100°C) and common household items such as sugar (melting point of 186°C, boiling point of 186°C).
Caprolactam is soluble in water and has a low viscosity. Its solubility in water is comparable to that of table salt, while its viscosity is similar to that of ethanol.
🏭 Production & Procurement
Caprolactam, a key precursor in the production of nylon-6, is typically manufactured through the Beckmann rearrangement of cyclohexanone oxime. This process involves the reaction of cyclohexanone oxime with concentrated sulfuric acid at high temperatures, resulting in the formation of Caprolactam.
Caprolactam can be procured through various chemical manufacturing companies that specialize in the production of nylon-6. It is typically transported in liquid form via tankers to different industrial facilities for further processing and utilization in the production of nylon fibers and resins.
Transportation of Caprolactam is carried out using specialized tanker trucks or railcars equipped with temperature control systems to prevent polymerization. These transportation methods ensure the safe and efficient delivery of Caprolactam to its intended destinations for use in the manufacture of various nylon products.
⚠️ Safety Considerations
Safety considerations for Caprolactam include potential irritation to the skin, eyes, and respiratory system. Proper personal protective equipment should be worn when handling this compound, including gloves, goggles, and a respiratory mask. In case of inhalation or skin contact, it is important to seek medical advice immediately.
The pharmacology of Caprolactam involves its conversion to cyclohexanone, which can further metabolize into caprolactam-gamma-valerolactam. These metabolites are then excreted in the urine, with a half-life ranging from 2-8 hours. Caprolactam is primarily used in the production of nylon-6, and its pharmacological effects in humans are minimal due to its rapid metabolism and excretion.
Hazard statements for Caprolactam include “Causes skin irritation” and “May cause respiratory irritation.” It is also classified as harmful if swallowed or inhaled. Additionally, wastewater containing Caprolactam should be treated properly before disposal to prevent environmental contamination.
Precautionary statements for Caprolactam include “Avoid breathing dust/fume/gas/mist/vapors/spray” and “Wear protective gloves/protective clothing/eye protection/face protection.” It is important to handle this compound in a well-ventilated area and to wash hands thoroughly after handling. In case of accidental exposure, seek medical advice immediately and provide the Safety Data Sheet for Caprolactam to medical personnel.
