| Umweltverhalten | TERRESTRIAL FATE: Based on a recommended classification scheme(1), an estimated Koc value of 286(SRC), determined from a structure estimation method(2), indicates that hexamethylene diamine is expected to have moderate mobility in soil(SRC). Volatilization of hexamethylene diamine is not expected from moist soil surfaces(SRC) given an estimated Henry's Law constant of 3.2X10-9 atm-cu m/mole(SRC), using a fragment constant estimation method(3). Volatilization of hexamethylene diamine from dry soil surfaces is not expected(SRC) based on an extrapolated vapor pressure of 0.12 mm Hg(SRC) at 25 °C(4). Biodegradation is expected to be an important environmental fate process for this compound(SRC). Standard BOD dilution techniques with activated sludge indicate that hexamethylene diamine biodegrades under aerobic conditions(5-7).AQUATIC FATE: Based on a recommended classification scheme(1), an estimated Koc value of 286(SRC), determined from a structure estimation method(2), indicates that hexamethylene diamine is expected to adsorb to suspended solids and sediment in water(SRC). Hexamethylene diamine is not expected to volatilize from water surfaces(3,SRC) based on an estimated Henry's Law constant of 3.2X10-9 atm-cu m/mole(SRC), developed using a fragment constant estimation method(4). An experimental pKa value of 11(5), indicates that hexamethylene diamine will not dissociate significantly at environmentally important pH values(SRC). Biodegradation is expected to occur slowly in aqueous environments(SRC). Degradation rates of 4% and 10% were observed for hexamethylene diamine (50 ppm) incubated in water from the Mino River, Japan and seawater off the coast of Japan over a 3 day incubation period(6). According to a classification scheme(7), an estimated BCF value of 1(3,SRC), from an estimated log Kow of 0.35(8,SRC), suggests that bioconcentration in aquatic organisms is low(SRC).ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), hexamethylene diamine, which has an extrapolated vapor pressure of 0.12 mm Hg at 25 °C(2,SRC), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase hexamethylene diamine is degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals(SRC)the half-life for this reaction in air is estimated to be about 6 hours(3,SRC). |

| TSCA Test Submissions | 1,6-Hexanediamine (CAS # 124-09-4) was evaluated for acute oral toxicity in Long Evans rats (5/sex/group) administered single gavage (free base) doses of 485, 679, 950, 1,330, and 1,960 mg/kg bodyweight and in additional groups given gavage doses of 950, 1,330, 1,860, 2,600, and 3,640 mg/kg. Treatment was associated with progressively more serious signs of toxicity with greater dosages. Pharmacotoxic signs upon oral administration of hexanediamine at doses of 485-1860 mg/kg bodyweight included immediate hypokinesis, hyperventilation, coarse body tremors, and abdominal grip. At doses of 1860 mg/kg and above, the adverse responses were profound and all animals were dead within 24 hours of dosing. An LD50 was 830 mg/kg with 95% confidence limits of 730 and 950 mg/kg. Necropsy of study lethalities revealed severe irritation of the mucous membranes and extensive gastrointestinal hemorrhaging.Hexamethylene Diamine, (CAS # 124-09-4) was evaluated in Charles River COBS CD rats (26/sex/group) administered measured dietary doses of 0, 50, 150, and 500 mg/kg bodyweight at 78.02% concentration in two successive generations (F0 and F1). A control group received the basal laboratory diet with an ethanol (solvent) concentration equivalent to that in the high-dose diet. F0 and F1 were mated once to produce F1 and F2 progeny, respectively. Treatment was associated with reduced bodyweight gains in high- and mid-dose F0 and F1 males and in high-dose F1 females. Food consumption was reduced in F0 and F1 females. High-dose F0 and F1 females demonstrated significantly lower weight gains during gestational periods. Fertility indices of dams and sires and the testes weights of males without litters did not reveal an adverse effect of treatment. Copulation, gestation, weaning intervals, and dynamics of dams were comparable to controls at all treatment levels in both generations. A 500 mg/kg high dose was associated with significant (p<0.05) reductions in both F1 and F2 progeny numbers as well as pup weights on lactation days 14 and 21. Smaller viable litter sizes did not correlate with increased numbers of dead pups. Survival through weaning was comparable in the progeny of control and all treated rats of both generations. Antemortem pathology on terminal necropsy of all high-dose and control parents revealed no gross lesions and no microscopic changes related to treatment. A dietary "no effect" level was 150 mg/kg day and researchers concluded that fetal developmental toxicity was produced only at levels associated with significant maternal toxicity.Hexamethylene diamine (1,6-diaminohexane, CAS# 124-09-4) was administered in the diet to groups of 52 rats (26 males and 26 females) at doses of 50, 150, and 500 mg/kg/day for two generations. A control group received the basal laboratory diet. The F0 and F1 generations were each mated once to produce F1 and F2 generations. Treatment related changes included reduction in weight in F0 males and F1 males and females and reduced food consumption among F0 and F1 males and females in the high dose group. The high dose group also showed reduced litter size, and decreased pup weight on lactation days 14 and 21 for both generations. No other treatment effects were noted with regard to lactation, female body weights, fertility indices, copulatory interval, gestation length, pup survival or appearance, or testes weight or appearance. The authors conclude that the 150 mg/kg/day level can be considered the dietary "no effect" level. This EPA status report only includes a summary of this study. |

| Artificial Pollution Sources | Hexamethylene diamine's production and use as a chemical intermediate in the production of nylon-type polyimide resins(1) may result in its release to the environment through a variety of waste streams(SRC). |
| Environmental Biodegradation | Biodegradation is expected to be an important environmental fate for this compound(SRC). Using a standard BOD dilution technique and an activated sludge inoculum, a theoretical BOD of 56% was observed during a 14 day incubation period(1). Using standard BOD dilution techniques and activated sludge inocula, theoretical BOD values of 41% to 56% were observed during a 14 day incubation period following a 6 day acclimation period(2). Based on 14 day BOD data, hexamethylene diamine is considered biodegradable(3). Following a 3 day acclimation period, 90% biodegradation of hexamethylene diamine in an activated sludge inoculum was observed during a 6 day incubation period, with an average COD of 26% per day(4). Degradation rates of 4% and 10% were observed for hexamethylene diamine (50 ppm) incubated in water from the Mino River, Japan and seawater off the coast of Japan over a 3 day incubation period(5). A theoretical oxygen demand between 20 and 60% was observed for hexamethylene diamine in a Warburg apparatus during a 5 day incubation period(6). |
| Environmental Bioconcentration | An estimated BCF value of 1 was calculated for hexamethylene diamine(SRC), using an estimated log Kow of 0.35(1,SRC) and a recommended regression-derived equation(2). According to a classification scheme(3), this BCF value suggests that bioconcentration in aquatic organisms is low(SRC). |

Anwendungen & Verwendung
Verwenden
Hexamethylenediamine is mainly used as a monomer to make nylon 6-6. Its derivative hexamethylene diisocyanate (HDI) is used in the production of polyurethane. It acts as a cross-linking agent in epoxy resins. Other applications include fiber, plastics, polyurethane coatings, lubricants, water treatment products and specialty chemicals (biocides, petroleum additives, and phenol purification).
Herstellung & Synthese
synthetische
Virtually all hexamethylenediamine is now produced by the catalytic hydrogenation of adiponitrile[111-69-3] :NC(CH2)4CN + 4H2 → H2N(CH2)6NH2.
