1,6-diaminohexane

1,6-Diaminohexane (also known as Hexamethylenediamine) is an organic compound with the formula H2N(CH2)6NH2. The compound is a colorless solid that is widely used in the production of polyamide resins and polyurethanes. It is derived from adipic acid, a key feedstock for the production of nylon.

Structure and properties

1,6-Diaminohexane is a diamine, which means it contains two amine groups. The molecule is linear, with the two amine groups separated by a chain of six carbon atoms. This structure gives the compound its name, as "hexane" refers to a six-carbon chain and "diamine" indicates the presence of two amine groups.

The compound is a solid at room temperature and is highly soluble in water. It has a strong, unpleasant odor and can be harmful if inhaled or swallowed.

Production

1,6-Diaminohexane is primarily produced from adipic acid, a dicarboxylic acid that is also used in the production of nylon. The process involves the reduction of adipic acid to 1,6-diaminohexane using hydrogen in the presence of a catalyst.

Uses

The primary use of 1,6-diaminohexane is in the production of nylon 6,6, a type of nylon that is widely used in textiles, carpets, and plastics. The compound is also used in the production of polyurethanes, which are used in a variety of applications including foams, coatings, and adhesives.

Safety

1,6-Diaminohexane can be harmful if inhaled or swallowed. It can cause irritation to the eyes, skin, and respiratory tract. Proper safety precautions should be taken when handling this compound, including the use of personal protective equipment and adequate ventilation.
