| 환경 거동 | TERRESTRIAL FATE: Based on a recommended classification scheme(1), an estimated Koc value of 260(SRC), determined from a structure estimation method(2), indicates that dicyclohexylamine is expected to have moderate mobility in soil(SRC). Volatilization of dicyclohexylamine from moist soil surfaces is expected given an estimated Henry's Law constant of 5.5X10-5 atm-cu m/mole(SRC), using a fragment constant estimation method(3). Dicyclohexylamine is not expected to volatilize from dry soil surfaces based on an estimated vapor pressure of 3.4X10-2 mm Hg(4).AQUATIC FATE: Based on a recommended classification scheme(1), an estimated Koc value of 260(SRC), determined from a structure estimation method(2), indicates that dicyclohexylamine is expected to adsorb to suspended solids and sediment in water(SRC). Dicyclohexylamine is expected to volatilize from water surfaces(3,SRC) based on an estimated Henry's Law constant of 5.5X10-5 atm-cu m/mole(SRC), developed using a fragment constant estimation method(4). Estimated volatilization half-lives for a model river and model lake are 1.1 and 12 days, respectively(3,SRC). According to a classification scheme(5), an estimated BCF value of 1200(3,SRC), from an estimated log Kow of 4.37(6,SRC), suggests that bioconcentration in aquatic organisms is very high(SRC). A biodegradation study based on BOD measurements, using an activated sludge seed, and an initial concentration of 100 mg/l, indicated 76.9% degradation of dicyclohexylamine after 2 weeks(7).ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), dicyclohexylamine, which has an experimental vapor pressure of 3.4X10-2 mm Hg at 25 °C(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase dicyclohexylamine 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 2.9 hours(3,SRC). |

| TSCA Test Submissions | Dicyclohexylamine (CAS # 101-83-7) was evaluated for acute oral toxicity in male and female Sprague-Dawley albino rats (alternately 2 and 3/sex/treatment level) administered single undiluted doses of 158, 200, 251 and 316 mg/kg. Treatment-related mortality was consistent with an Oral LD50 (with 95% confidence limits) of 240 (205-285) mg/kg as follows: 158 mg/kg (0/2M0/3F), 200 mg/kg (0/3M1/2F), 251 mg/kg (1/2M2/3F), and 316 mg/kg (3/3M1/2F). Death occurred from several hours to 24 hours after dosing. Pharmacotoxic signs included reduction in food consumption and activity (1 day in survivors), progressive weakness, prostration and death. Upon gross necropsy of the study lethalities, treatment-related changes of visceral organs included focal hemorrhaging of the lungs, discolored liver and acute inflammation of the gastrointestinal tract. Study survivors of 14-day post-treatment observation were free of any gross treatment-related pathology at terminal sacrifice. This study was briefly summarized. No further information was reported.Dicyclohexylamine (CAS # 101-83-7) was evaluated for acute dermal toxicity in solitary male or female New Zealand albino rabbits administered single undiluted dermal applications of 126, 316 and 501 mg/kg for 24 hours. Two male and 3 female rabbits each were administered doses of 200 mg/kg. Treatment-related mortality was consistent with a Dermal LD50 in rabbits of 200-316 mg/kg as follows: 200 mg/kg (1/2M0/3F), 316 mg/kg (1/1F), and 501 mg/kg (1/1M). Death occurred prior to 16th hour post-treatment observation in all cases. A solitary male of the 126 mg/kg dose and a male and 3 females of 200 mg/kg doses survived to the 14th day end of post-treatment observation and terminal sacrifice. Pharmacotoxic signs associated with treatment included reduced appetite and activity (2-3 days in survivors), progressive weakness, prostration and death. Upon terminal necropsy of study lethalities, focal hemorrhage of the lungs, discoloration of liver, enlarged gall bladder and inflammation of the gastrointestinal tract were identified. Terminal sacrifice of the study survivors found them with normal-appearing viscera and no gross treatment-related pathology. This study was briefly summarized. No further information was reported.Dicyclohexylamine (CAS # 101-83-7) was evaluated for acute inhalation toxicity in 6 male New Zealand albino rabbits administered whole-body exposures to 1.4 mg/L for 6 hours. A 2.1 g sample was vaporized and supplied to the 35L exposure chamber via an air flow rate of 4.0 L/min. There was no mortality associated with treatment. Treated rabbits exhibited slight lethargy only, which resolved immediately after termination of the exposure and no further untoward effects of toxicity were noted throughout 14-day post-exposure observation. Upon terminal necropsy, all viscera appeared normal. This study was briefly summarized. No further information was reported.Dicyclohexylamine (CAS # 101-83-7) was evaluated for primary dermal irritation in 6 New Zealand albino rabbits each administered 0.5 ml undiluted dermal applications to both intact and abraded skin for 24 hours. The unanimous response and a 24-72 hour average primary irritation score was assigned a classification of corrosive. Continued observation found loosening at the edges of the resultant scab showing injury in depth within 17 to 21 days after treatment. This study was briefly summarized. No further information was reported.Dicyclohexylamine (CAS # 101-83-7) was evaluated for acute eye irritation in 6 New Zealand albino rabbits administered single 0.1 ml undiluted ocular instillations for 24 hours. A 24-72 hour average irritation score of 32.6/110 reflected an overall response assigned a classification of moderately irritating. Treatment initially caused severe discomfort and rabbits pawed and tightly closed the treated eyes. At 1 hour post-treatment, severe erythema was apparent that was unresolved at 24th hour examination. The 24th hour post-instillation examination also found treated rabbits with slight corneal cloudiness and a sluggish iridic reaction to light. Gradual improvement was seen over the ensuing 48-168 hours and, at 14th day examination, all treated eyes were clear of any signs of irritation. This study was briefly summarized. No further information was reported. |

Dicyclohexylamine (DCHA) is an aliphatic amine. As an intermediate, it can be used in a broad range of applications in different industries. Dicyclohexylamine is used as a vulcanization accelerator. In lubricants and cutting fluids it does function as a corrosion inhibitor. Here it should be mentioned that Dicyclohexylamine does not form Nitrosamines when being used. Reagent for preparation of crystalline amino acid derivative salts. Dicyclohexylamine was used to constitute ionic liquid matrices for bacterial analysis in matrix assisted laser desorption/ionisation mass spectrometry. It was used to develop a new palladium catalyst for Suzuki coupling reaction of aryl bromides with boronic acids. It was used as extractant in determination of gold(III) by dispersive liquid-liquid microextraction and electrothermal atomic absorption spectrometry.
제조 및 합성 방법
생산 방법
Several methods are employed for the manufacture of dicyclohexylamine. It can be manufactured by hydrogenation of equimolar amounts of cyclohexanone and cyclohexylamine. Alternatively, dicyclohexylamine can be prepared by vapor phase catalytic hydrogenation of aniline at elevated temperature and pressure. Fractionation of the crude reaction product yields cyclohexylamine, unreacted aniline, and a high boiling residue comprised of N-phenylcyclohexylamine and dicyclohexylamine (Windholz et al 1983).
