储存注意事项 储存于阴凉、通风良好的专用库房内,远离火种、热源。库温不宜超过37℃,保持容器密封。应与氧化剂、酸类、碱金属等分开存放,切忌混储。采用防爆型照明、通风设施。禁止使用易产生火花的机械设备和工具。储区应备有泄漏应急处理设备和合适的收容材料。

稳定性

1.化学性质:具有饱和一元醇的通性,由于只有一个碳原子,因此有其特有的反应。例如:① 与氯化钙形成结晶状物质CaCl2·4CH3OH,与氧化钡形成BaO·2CH3OH的分子化合物并溶解于甲醇中;类似的化合物有MgCl2·6CH3OH、CuSO4·2CH3OH、CH3OK·CH3OH、AlCl3·4CH3OH、AlCl3·6CH3OH、AlCl3·10CH3OH等;② 与其他醇不同,由于-CH2OH基与氢结合,氧化时生成的甲酸进一步氧化为CO2;③ 甲醇与氯、溴不易发生反应,但易与其水溶液作用,最初生成二氯甲醚(CH2Cl)2O,因水的作用转变成HCHO与HCl;④ 与碱、石灰一起加热,产生氢气并生成甲酸钠;CH3OH+NaOH→HCOONa+2H2;⑤ 与锌粉一起蒸馏,发生分解,生成CO和H2O。

2.甲醇为有毒化工产品,具有显著的麻醉作用,对于视神经危害最为严重。饮入5~10ml/kg甲醇可致严重中毒,10ml/kg以上有失明危险,饮入30ml/kg可以致死。甲醇可经消化道、呼吸道及皮肤渗透侵入人体导致中毒。吸入浓的甲醇蒸气时,除了特有的症状酩酊、头痛以外,常使视力模糊而眼痛。这些症状有的在数小时之后即能发生,重症时,呈现眩晕、呼吸困难、胃痛、疝痛、便秘,有时还会有出血,需要数日才恢复。在这期间也能引起疲劳、不适,重症时能出现发绀。不论急性、慢性都需要较长时间才能恢复。工作场所空气中甲醇蒸气最高容许浓度260mg/m3。防护方法在于生产设备密闭,严防入口、入眼或接触伤口。如有黏沾,迅速用水冲洗。急性中毒者迅速移到新鲜空气处。严重者送医院诊治。

3.属中等毒类。主要作用于神经系统,具有麻醉作用。可被皮肤吸收、饮用或吸入蒸气而造成中毒,其特征是刺激视神经及网膜,导致眼睛失明。乙醇在体内能迅速分解排除,而甲醇排出缓慢,故有累积性。吸入甲醇蒸气会刺激眼、鼻和咽喉,引起眩晕、头痛、沉醉、流泪和视力模糊。重症时呈现麻醉、呼吸困难、恶心、呕吐、胃痛、疝痛、膀胱痛、便秘、有时还会出血。一般误饮5~10ml可致严重中毒,15ml可致失明,30ml左右可致死。兔经口致死量为10ml/kg。嗅觉阈浓度140mg/m3。TJ36-79规定车间空气中最高容许浓度为50mg/m3。

三、急救措施

皮肤接触:脱去被污染的衣着,用肥皂水和清水彻底冲洗皮肤。 眼睛接触:提起眼睑,用流动清水或生理盐水冲洗。就医。吸入:迅速脱离现场至空气新鲜处。保持呼吸道通畅。如呼吸困难,给输氧。如呼吸停止,立即进行人工呼吸。就医。 食入:饮足量温水,催吐,用清水或1%硫代硫酸钠溶液洗胃。就医。

灭火方法:尽可能将容器从火场移至空旷处。喷水保持火场容器冷却,直至灭火结束。处在火场中的容器若已变色或从安全泄压装置中产生声音,必须马上撤离。灭火剂:抗溶性泡沫、干粉、二氧化碳、砂土。

1.工业上合成甲醇几乎全部采用一氧化碳加压催化加氢的方法,工艺过程包括造气、合成净化、甲醇合成和粗甲醇精馏等工序。粗甲醇的净化过程包括精馏和化学处理。化学处理主要用碱破坏在精馏过程中难以分离的杂质,并调节pH值;精馏主要是脱除易挥发组分如二甲醚,以及难挥发组分职乙醇、高碳醇和水。粗馏后的纯度一般都可达到98%以上。

2.将工业甲醇用精馏的方法将含水量降到0.01%以下。再用次碘酸钠处理,可除去其中的丙酮。经精馏得纯品甲醇。

3.BV-Ⅲ级甲醇的制备主要采用精馏工艺。以工业甲醇为原料,经精馏、超净过滤、超净分装,得高纯甲醇产品。

4.一般均以工业甲醇为原料,经常压蒸馏除去水分,控制塔顶64~65℃,过滤除去不溶物即可。
