  • Rates of acetylation of alcohols and phenols can be greatly increased by hypernucleophilic catalysis with DMAP (4-(Dimethyl­amino)­pyridine, A13016). See also 2-Hydroxypyridine, A14522 and Tri-n-butyl­phosphine, A12649. The use of certain metal triflates as catalysts is also effective; see, e.g. Scandium(III)­ trifluoromethanesulfonate hydrate, 40566, and Ytterbium(III)­ trifluoromethanesulfonate hydrate, 40314. CoCl2 catalysis in acetonitrile has been reported to promote selective acetylation of primary alcohols in the presence of secondary and tertiary: J. Org. Chem., 57, 2001 (1992), and formation of 1,1-diacetoxy-derivatives from aromatic aldehydes, but with aliphatic aldehydes, 1,2-diones are formed: J. Org. Chem., 56, 3283 (1991); 58, 5578 (1993).
  • Can be used to activate Dimethyl­ sulfoxide, A13280, for mild, selective oxidation of alcohols to aldehydes or ketones (Albright-Goldman oxidation) at room temperature without added base (cf Swern: Oxalyl­ chloride, A18012): J. Am. Chem. Soc., 43, 2480 (1965); J. Org. Chem., 53, 2144 (1988).

  • 方法一:有以下几种工艺路线:1.乙酸裂解法(烯酮法) 以丙酮或乙酸为原料,首先热分解生成中间体乙烯酮,然后将含乙烯酮气体在两个串联的填充塔中用乙酸和乙酐的混合物(循环液)淬冷同时进行化学吸收,生成乙酐: H2C=C=O+CH3COOH—(CH3CO)2O工艺过程如下:将乙酸在蒸发器内气化,于20kPa,负压下与磷酸催化剂混合并通过预热分解器预热至600℃,进行分解管,在700-720℃下热分解成含水和乙酸的乙烯酮。为避免生成沸点与乙酐相近的双乙烯酮(沸点127.4℃),在预热分解管出口处通入氨,经冷却器急冷至0℃左右,分离出水和末反应的乙酸,而后将除去乙酸的反应气体送入吸收塔,与乙酸反应生成乙酐。第一吸收塔控制温度30-40℃,乙酐浓度为85%,第二吸收塔控制温度20℃,乙酐浓度为10-20%,为保持吸收塔的乙酸浓度,在第二吸收塔中定期加入冰醋酸,并将第二吸收塔的乙酸循环至第一吸收塔作吸吸夜用。自第一吸收塔循环液中抽取的粗乙酐去精留馏塔精馏,可得浓度95%以上的乙酐。此法产生步骤多,能耗大,乙酐总收率仅约70%,是较陈旧的方法。用丙酮热解时,裂解温度650-800℃,停留时间0.25-0.75s,加入少量二硫化碳以抑制碳生成,产物用乙酸淬冷.生成的乙烯酮再以乙酸吸收即成乙酐。2.乙醛氧化法院 其反应如下:2CH3CHO+O2——(CH3CO)2+H2O以乙醛为原料,以乙酸钴-乙酸铜为催化剂,在45-55℃,0.29-0.39MPa用空气或氧进行液相催化氧化,产物中乙酐占40%,如加入乙酸乙酯作稀释剂,则成品乙酐可提高50%,粗品经精制分离而得。工艺过程如下:原料乙醛加入稀释剂乙酸乙酯和催化剂乙酸钴,碳酸铜,再加入乙酸和回汽水,配成氧化料,将氧化料连续加入氧化塔底部,自塔身各节通入氧气,反应温度控制在40-60℃之间压力维持在100-300kPa,连续出料,出料的料液中含醛量应不超过2%,尾气通入吸收塔用水吸收。料液在去酯工序将反应产生的水分迅速随着乙酯馏出,防止生成的乙酐水解成乙酸。再在去催化剂塔馏出酐酸混合液,催化剂留在塔釜内,贮积较浓后蒸去塔内残存酐酸,放出催化剂处理回用。酐酸混合液在酐酸分离塔将乙酐和乙酸分开.分离塔为不锈钢真料塔,操作时间真空度53.3-80kPa,塔顶出料为乙酸,塔底出料为粗乙酐。粗乙酸在不锈钢精制制塔内减压蒸去低沸物后,收集成品乙酐。此法操作简单,同时得到副产品乙酸,是目前乙酐的主要生产方法.乙醛氧化法的消耗定额:乙醛1681kh/t,乙酸乙酯70kg/t,氧气571kg/t。3.乙酸甲酯羰化法 以甲醇和乙酸为原料,使用铑系催化剂,以铬的化合物作助催化剂,羰基化生成乙酐。工业上分两步进行:第一步是甲醇酯化为乙酸甲酯;第二步是乙酸酯羰化生成乙酐,温度175℃,压力25MPa,生成乙酐的选择性为95%。这个过程的研究和发展,被看作碳一化学的一项成就,引起各国的重视。4.乙酰氯法乙酰氯与乙酸钠反应制得。
  • 防护措施:有毒。对眼及粘膜具有强烈的刺激性,浓度为0.36mg/m3时即对眼有刺激;0.18mg/m3时,就能改变人的脑电图象。还能引起细胞组织蛋白质变质。其蒸气刺激性更强,极易烧伤皮肤及眼睛,如经常接触会引起皮炎和慢性结膜炎。对大鼠经口LD50为1780mg/kg。当溅及或粘附于皮肤时,要立即用清水或2%苏打水冲洗,全身中毒时应延医诊治。空气中最高容许浓度5ppm。设备应密封,防止泄漏。操作人员要穿戴好防护用品。
