Toxicological data

1. Acute toxicity LD50: 750mg/kg (rat oral); 1110mg/kg (rabbit skin);

2. Irritant No information

3. Subacute and chronic toxicity Rats were exposed to the poison at a concentration of 7mg/m3 for 3 and a half months, and there were histological changes in the blood vessels of the lung, liver and kidney. Repeated administration of hexamethylenediamine to guinea pigs caused anemia, weight loss, and mild degeneration of the kidney and liver and myocardium under the microscope.

4. The lowest oral toxic dose (TDLo) for other rats: 3g/kg (administered on the 6th to 16th day of pregnancy), causing embryo toxicity and abnormal development of the liver system. The lowest oral toxic dose (TDLo) for rats: 1840mg/kg (for 6-16 days of pregnancy), causing abnormal development of the genitourinary system.

1. Most of this product is used to synthesize nylon 66 and 610 resin, also used to synthesize polyurethane resin, ion exchange resin and hexylene diisocyanate, as well as curing agent for urea-formaldehyde resin, epoxy resin, etc., organic crosslinking agent It is also used as stabilizer and bleaching agent in textile and paper industry, corrosion inhibitor of aluminum alloy and emulsifier of neoprene. Hexanediamine and hydrochloric acid form a salt below 28°C to obtain 1,6-hexamethylenediamine hydrochloride (6055-52-3), which can be used to produce chlorhexidine acetate, a bactericide. Hexanediamine also has some applications in the production of adhesives, aviation coatings and rubber vulcanization accelerators.

2. This product is used as a curing agent for urea-formaldehyde resin and epoxy resin. The dosage is 15 parts, and the curing condition is 25℃ for 1 day, which can improve the flexibility of the product. This product is used to prepare nylon 66, nylon 610, adhesives and coatings. Also used as a rubber vulcanization accelerator.

3. Used in organic synthesis, production of polymers (such as nylon 66), and also used as epoxy resin curing agent and chemical reagent.
