Environmental Fate · 4 条

TERRESTRIAL FATE: Based on a classification scheme(1), Koc values of 2,755-17,416, determined in five European reference soils(2), indicates that anthraquinone is expected to have slight mobility or be immobile in soil(SRC). Volatilization of anthraquinone from moist soil surfaces is not expected to be an important fate process(SRC) given an estimated Henry's Law constant of 2.35X10-8 atm-cu m/mole(SRC), based upon its vapor pressure, 1.16X10-7 mm Hg(3), and water solubility, 1.35 mg/L(4). Anthraquinone is not expected to volatilize from dry soil surfaces(SRC) based upon its vapor pressure. Direct photolysis is possible on sunlit solid surfaces(5). Biodegradation of anthraquinone is expected to be a major fate process for this compound in soil; 68% of added anthraquinone was biodegraded by a mixed soil population within 12 weeks(6). A mixed bacterial population, isolated from a coal-tar contaminated soil, biodegraded anthraquinone even faster with only 6.5% of the initial concentration of anthraquinone remaining after 3 days(7). A BOD/ThOD of 54% and a CO2/ThCO2 of 41% were measured in a biodegradation study using a garden soil inoculum and a 58-day incubation period(8). Rapid degradation, apparently due to microbial activity, has been reported for different soils with half-lives of 7-10 days(5).

AQUATIC FATE: Based on a classification scheme(1), Koc values of 2755-17416, determined in five European reference soils(2), indicate that anthraquinone is expected to adsorb to suspended solids and sediment(SRC). Volatilization from water surfaces is not expected(3) based upon an estimated Henry's Law constant of 2.35X10-8 atm-cu m/mole(SRC) derived from its vapor pressure, 1.16X10-7 mm Hg(4), and water solubility, 1.35 mg/L(5). According to a classification scheme(6), an estimated BCF of 12(SRC), from its log Kow of 3.39(7) and a regression-derived equation(8), suggests the potential for bioconcentration in aquatic organisms is low(SRC). Anthraquinone is stable to aqueous environmental hydrolysis, but sensitive to light with a reported direct photolysis half-life of about 9 minutes in aqueous solution(9).

AQUATIC FATE: Biodegradation of anthraquinone in the water column is expected to be a major fate process. Over a three day period, 82% of the added anthraquinone (at 10 mg/L) was degraded by river water, 91% was degraded by sea water(1). Biodegradation using mixed cultures from seawater degraded anthraquinone 50% over 10 days; metabolite concentration was low but included mainly benzoic and phthalic acids(2). Mixed bacterial populations from groundwater were able to completely degrade anthraquinone within 5 days(3). From 50-100% degradation has been reported using activated sludge as an inoculum and a three week incubation period(4-9).

ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), anthraquinone, which has a vapor pressure of 1.16X10-7 mm Hg at 25 °C(2), will exist in both the vapor and particulate phases in the ambient atmosphere. Vapor-phase anthraquinone 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 11 days(SRC), calculated from its rate constant of 1.5X10-12 cu cm/molecule-sec at 25 °C(SRC) that was derived using a structure estimation method(3). Anthraquinone absorbs at wavelengths >290nm(4) and therefore may be susceptible to direct photolysis by sunlight(SRC). Anthraquinone is sensitive to light in aqueous solution with a reported half-life of about 9 minutes(6) which suggests direct photolysis in air may be important(SRC). Particulate-phase anthraquinone may be removed from the air by wet or dry deposition(SRC); anthraquinone has been detected in rain water from several storm events(5).

The quinones are alpha-beta-unsaturated ketones and react with sulfhydryl (-SH) groups. This reaction has been suggested as the critical biochemical lesion involving the -SH groups of enzymes such as amylase and carboxylase which are inhibited by quinones. ... Overall /fungicidal/ mechanism may involve binding of enzyme to quinone nucleus by substitution or addition at the double bond, oxidative reaction with -SH group, and change in redox potential. /Quinones/

Yields anthrone, 9,10-dihydroxyanthracene, and 2-hydroxyanthraquinone in rats. /from table/

Quinones (ie, 6,12-dione) have been shown to undergo oxidation-reduction cycles involving quinone, hydroquinone, and molecular oxygen, resulting in the formation of oxygen radicals and semiquinone radicals. /Quinones/

Anthraquinone (labelled with 14C in the 9,10-positions) was administered orally in a dose of 5 mg/kg bw to male rats and the urine and the feces of the animals were collected until 48 hr after administration: the elimination ratio (renal: fecal) amounted to about 1:1.6. The main elimination product in feces, anthraquinone amounted to minimum 40% of the totally recovered radioactivity (in the excreta and the carcass 48 hr after administration), non conjugated 2-hydroxy-anthraquinone as a minor fecal metabolite was found in approximately 4%. Urine contained as main biotransformation product (approximately 20% of the totally recovered radioactivity) conjugated 2-hydroxy-anthraquinone, unchanged anthraquinone amounted to about 1% in the urine.

In a study of the metabolism of anthraquinone, rats were maintained for 4 days on a diet containing 5% of anthraquinone, the urines being collected daily. The following urinary metabolites were detectable: 2-hydroxyanthraquinone and its sulphuric ester, conjugates of 9-hydroxy-, 9,10-dihydroxy- and 2,9,10-thrihydroxyanthracene and anthrone.

A metabolism study was conducted using male Fischer 344 rats in which they were fed formulations of 4 lots of anthraquinone, produced by three different synthetic routes, with concentrations of 938, 3750 and 7500 ppm and a control diet containing no anthraquinone in irradiated NTP 2000 feed for seven consecutive days. One of the lots had been previously used to conduct subchronic and chronic rodent toxicity studies in feed. Ten animals were used per group. The formulations were prepared using anthraquinone with particle sizes smaller than 80 mesh and consistent in distribution for each lot. All animals were placed in individual metabolism cages following dosing and urine was collected for 24 hours. The urine of all animals from each group was pooled. The purpose of this study was to evaluate any difference in absorption and metabolism of the anthraquinone. A high performance liquid chromatographic method with ultraviolet absorbance detection (HPLC/UV) was developed to analyze the urine samples for 1- and 2-hydroxyanthraquinone, metabolites of anthraquinone. The method consisted of extracting 2 mL of urine with three 2-mL aliquots of ethyl acetate, combining them, evaporating, and reconstituting in 25% water:75% acetonitrile. The reconstituted extracts were analyzed using a C18 reverse-phase column, a mobile phase starting at 75% water:25% acetonitrile, remaining there for 5 minutes and then going to 25%water:75% acetonitrile over 20 minutes with a linear gradient, and a detection wavelength of 260 nm. This method was validated and found to have acceptable linearity, specificity, sensitivity, accuracy, precision, recovery, and ruggedness. Analysis of the samples found that the metabolic profiles and concentrations were consistent for each source of anthraquinone at a given dose level. 1- and 2-hydroxyanthraquinone and anthraquinone were found in all samples from the dosed animals. Within a given sample the concentrations of 2-hydroanthraquinone and anthraquinone were similar and the concentration of 1-hydroxyanthraquinone was approximately 2% of the other two.

Absorption, Distribution and Excretion · 2 条

Following a single oral administration of anthraquinone (labelled with 14C in the 9,10-positions) at dose levels of 0.1, 1.0, 3.0 mg/kg bw (male rats) or of 1.0 mg/kg bw (females rats), the radioactivity resulting from anthraquinone was nearly completely absorbed, the absorption commencing after a short lag period of about 2-3 minutes. After dosing male or female rats with 1.0 mg/kg bw, the absorption could not be described by a unique half-life. Following administration of 0.1 mg/kg bw to males, the absorption period was best characterized by a half-life of roughly 40 minutes, the maximum plasma level of P=0.75 was reached after 2.5 hr. Following oral administration of 1.0 mg/kg bw to males of females, the plasma concentration peaked after 5 hr (P=0.46) and 12 hr (P=0.43), respectively. The radioactivity was slowly eliminated form the body: 2 days after oral intubation on average about 5% of the administered dose could be measured in the body excluding the GI tract, within 2 days after oral administration <0.01% of the recovered radioactivity were excreted with the expired air. Within the test interval of 2 days about 95% of the retrieved radioactivity were excreted with urine and feces after oral administration, the ratio of the amounts excreted via both routes was about 1.6 (feces:urine). At sacrifice of the male rats 48 hr after administration of 1.0 mg/kg bw, a relative concentration of P=0.052 was determined in the body excluding the GI tract. In the kidney and in the liver these values were about 7 times higher and in the brain they were about 10 times lower as compared with the sum of all organs tissues. At sacrifice of the females a relative concentration of P=0.063 was determined in the body excluding the GI tract and in the kidney and in the liver these vales were about 8 times higher and in the fat and in the brain the relative concentrations were 4 times and 8 times, respectively, lower (results representing the sum of the unchanged substance and its labelled metabolites. P=relative concentration=activity measured/grams of plasma: activity administered/grams of bw).

/In animals/ elimination is quick; almost 96% is excreted within 48 hr in the urine and feces.

制备方法 · 2 条

生产方法在第一次世界大战前,蒽醌产量很小,仅有以重铬酸钠将蒽氧化为蒽醌的一种生产方法。20世纪40年代发展了蒽的气相催化氧化法。目前,在美国广泛采用苯酐法。近年来,又发展了萘醌法和苯乙烯法。1.蒽气相催化氧化法蒽氧化法是以精蒽为原料,以空气作氧化剂,五氧化二钒为催化剂,进行气相催化氧化,反应器有固定床和硫化床两种类型。 我国蒽醌生产厂大多采用固定床反应器,用含量大于90%的精蒽,熔化后用300℃左右的热空气以1560立方米/h的流速带出汽化精蒽,在热风管道中混合后通过固定床催化氧化的列管反应器,总收率达80%-85%。原料消耗定额:精蒽(90%)1260kg/t。氧化蒽醌所用原料精蒽来自煤焦油蒸馏,不含无机离子。氧化蒽醌的生产过程中,主要采用蒸馏和气相催化氧化,没有废水废气产生,不会产生氯离子、硫酸根离子和铁离子等,所以氧化蒽醌在用作高档染料方面具有竞争优势。其缺点是原料精蒽受煤焦油产品的制约。2.苯酐法 以苯酐、苯为原料,以三氯化铝为催化剂,进行付-克(Friedel-Crafts)反应,然后用浓硫酸脱水生成蒽醌。苯酐法又分为溶剂法、球磨法和气相缩合法。我国大多采用溶剂法,即以过量的苯为溶剂。此法原料易得,可以从石油做起,具有反应温度低、设备简单、副反应少等优点。缺点是污染严重,三氯化铝废酸水不易处理,而且生产成本高。我国合成蒽醌均采用苯酐法。原料消耗定额:苯酐768kg/t、纯苯700kg/t、硫酸(98%)1364kg/t、三氯化铝1554kg/t、发烟硫酸1000kg/t。3.萘醌法以萘醌和丁二烯为原料,以氯化亚铜为催化剂,进行缩合反应、脱氢后得蒽醌。由于石油化工的飞速发展,提供了此法所用的大量原料丁二烯和萘醌。该法具有消耗低、三废少等优点,在日本和美国萘醌法已达到相当规模,有发展前途。日本川崎公司使用此法生产。我国科研部门进行过大量研究,虽然小式、中式均已成功,但未工业化生产。该法的缺点是萘醌和丁二烯本身价格较高,目前,由于反应动力学研究不够,催化剂性能不佳,经常出现床层飞温烧床,操作弹性小。4.苯乙烯法 由苯乙烯先进行二聚反应,然后氧化成邻苯酰基苯甲酸,再环合成蒽醌。该方法的优点是原料易得,没有苯酐法的铝盐废水引起的公害问题,产品成本较低。但反应条件较苛刻,技术复杂,设备要求高,是德国BASF研究的新成果,但目前还未放大到工业生产规模。此外,日本三井化学公司获得了以甲苯为原料制备蒽醌的专利。由于工艺简单、原料便宜,引起了人们的关注。

生产方法精蒽氧化法气相固定床氧化法 将精蒽加入气化室加热气化后与空气混合,二者比例为1︰(50~100)。混合气体进入氧化室,在V2O5催化下于(389±2) ℃下氧化,经薄壁冷凝后即得产品。液相氧化法 将精蒽计量后加入反应釜,再加入三氯苯在搅拌下溶解。然后滴加硝酸,控制反应温度105~110 ℃,将副产物NO排除,反应6~8 h后,减压蒸出溶剂,冷却结晶。得产品。此法设备腐蚀严重。苯酐法 将苯酐计量后加入反应釜,加苯在搅拌下加热熔解。加热至370~470 ℃,使混合气通过硅铝催化剂进行气相缩合。得产品。羧基合成法 将计量的苯加入反应釜,在4.88 MPa下通CO,于200 ℃反应4 h,一直通到CO压力不再下降,反应结束。经处理得产品。
