Hexamethylenediamine CAS#124-09-4
1. Essential for Nylon Production: Key raw material in the manufacturing of nylon 6,6 and other synthetic polymers.
2. Versatile Applications: Used in the production of adhesives, coatings, and plasticizers.
3. High Solubility: Soluble in alcohol and highly soluble in water (490 g/L), making it effective in various chemical processes.
4. Stable and Combustible: Stable under normal conditions, but should be handled carefully due to its combustibility and chemical reactivity.
Hexamethylenediamine (also known as 1,6-diaminohexane) is an organic compound that contains two amine functional groups. This diamine consists of a six-carbon chain, with amino groups attached at both ends. It appears as a colorless solid and has a strong, pungent odor reminiscent of ammonia, similar to that of piperidine.
Hexamethylenediamine is widely used in the production of nylon 6,6 and other synthetic polymers. It is also utilized in the manufacture of adhesives, coatings, and plasticizers. Due to its strong odor and chemical reactivity, it should be handled with care in a controlled environment.
