Source

1-Butanol naturally occurs in white mulberries and papaya fruit (Duke, 1992). Identified as one of 140 volatile constituents in used soybean oils collected from a processing plant that fried various beef, chicken, and veal products (Takeoka et al., 1996).

환경귀착

2Biological. 1-Butanol degraded rapidly, presumably by microbes, in New Mexico soils releasing carbon dioxide (Fairbanks et al., 1985). Bridié et al. (1979) reported BOD and COD values of 1.71 and 2.46 g/g using filtered effluent from a biological sanitary waste treatment plant. These values were determined using a standard dilution method at 20 °C for a period of 5 d. Heukelekian and Rand (1955) reported a similar 5-d BOD value of 1.66 g/g which is 64.0% of the ThOD value of 2.59 g/g. Using the BOD technique to measure biodegradation, the mean 5-d BOD value (mM BOD/mM 1-butanol) and ThOD were 3.64 and 60.7%, respectively (Vaishnav et al., 1987). In activated sludge inoculum, following a 20-d adaptation period, 98.8% COD removal was achieved. The average rate of biodegradation was 84.0 mg COD/g?h (Pitter, 1976).
Photolytic. An aqueous solution containing chlorine and irradiated with UV light (λ = 350 nm) converted 1-butanol into numerous chlorinated compounds which were not identified (Oliver and Carey, 1977).
Reported rate constants for the reaction of 1-butanol and OH radicals in the atmosphere: 6.8 x 10-10 cm3/molecule?sec at 292 K (Campbell et al., 1976), 8.31 x 10-12 cm3/molecule?sec (Wallington and Kurylo, 1987). Reported rate constants for the reaction of 1-butanol and OH radicals in the atmosphere: 8.3 x 10-12 cm3/molecule?sec at 298 K (Atkinson, 1990); with OH radicals in aqueous solution: 2.2 x 10-9 L/molecule?sec (OH concentration 10-17 M) (Anbar and Neta, 1967). Based on an atmospheric OH concentration of 1.0 x 106 molecule/cm3, the reported half-life of 1-butanol is 0.96 d (Grosjean, 1997).
Chemical/Physical. Complete combustion in air yields carbon dioxide and water vapor. Burns with a strongly luminous flame (Windholz et al., 1983).
1-Butanol will not hydrolyze because it has no hydrolyzable functional group (Kollig, 1993).
At an influent concentration of 1,000 mg/L, treatment with GAC resulted in an effluent concentration of 466 mg/L. The adsorbability of the carbon used was 107 mg/g carbon (Guisti et al., 1974).

저장

Store n-butyl alcohol in a cool, dry, well-ventilated location, away from smoking areas. Fire hazard may be acute. Outside or detached storage is preferred. Separate from incompatibles. Containers should be bonded and grounded for transfer to avoid static sparks

Purification Methods

Dry it with MgSO4, CaO, K2CO3, or solid NaOH, followed by refluxing with, and distillation from, small amounts of calcium, magnesium activated with iodine, or aluminium amalgam. It can also be dried with molecular sieves, or by refluxing with n-butyl phthalate or succinate. (For method, see Ethanol.) n-Butanol can also be dried by efficient fractional distillation, water passing over in the first fraction as a binary azeotrope (contains about 37% water). An ultraviolet-transparent distillate has been obtained by drying with magnesium and distilling from sulfanilic acid. To remove bases, aldehydes and ketones, the alcohol is washed with dilute H2SO4, then NaHSO4 solution; esters are removed by boiling for 1.5hours with 10% NaOH. It has also been purified by adding 2g NaBH4 to 1.5L butanol, gently bubbling with argon and refluxing for 1 day at 50o. Then adding 2g of freshly cut sodium (washed with butanol) and refluxed for 1day. Distil and collect the middle fraction [Jou & Freeman J Phys Chem 81 909 1977]. [Beilstein 1 IV 1506.]

Toxicity evaluation

The primary effects observed following oral and inhalation exposure in rats and mice to n-butyl alcohol include neurological and neurodevelopmental effects. n-Butyl alcohol has been evaluated in a large number of experimental animal and in vitro studies examining possible mechanisms for alcoholinduced neurotoxicity. One proposed mechanism is that alcohols, in general, produce neurological changes by disrupting the lipid bilayer. A few experimental animal studies have shown that n-butyl alcohol, like other alcohols, can disrupt membrane integrity. Other in vitro and experimental animal studies have demonstrated that n-butyl alcohol interacts with protein-receptors and modulates their effects such that it potentiates inhibitory g-aminobutyric acid (GABA) and glycine receptors and inhibits excitatory neuronal receptors such a glutamate. This modulatory action of n-butyl alcohol is supportive of the observed neurobehavioral changes (e.g., central nervous system (CNS) depressant profile) associated with n-butyl alcohol exposure in humans.
In addition, experimental animal studies have shown that n-butyl alcohol inhibits fetal rat brain astroglial cell proliferation by disrupting the phospholipase D (PLD) signaling pathway. Inhibition of astroglial cell proliferation, which has been postulated as a mode of action for ethanol-induced microencephaly and mental retardation observed in cases of fetal alcohol syndrome. These mechanisms can also be relevant to the observed dilation in the brain that has been noted in animals gestationally exposed to n-butyl alcohol.
