| description | The invention discloses a method for preparing ethanol with ultralow metal ion concentration. Absolute ethanol produced from tapioca flour through fermentation is taken as a raw material and processedwith a heating reflux method, an ethanol liquid is distilled off in a sub-boiling state, and metal ions in ethanol is removed. The metal ion concentration of purified ethanol is ultralow and is tested and verified by a Perkin Elmer-PinAAcle 900T type atomic absorbing instrument. The method has the beneficial effects as follows: the method and equipment for improving purity of ethanol by a simpledevice are invented, chemical development is promoted, and particularly, the method has great significance for promoting production and popularization of electronic grade ethanol.
本文公开了种制备超低金属离子浓度乙醇的方法。以木薯粉发酵生产的无水乙醇为原料用加热回流法，将乙醇液体在亚沸状态时蒸出，从而除去乙醇中的金属离子。提纯后的乙醇中含有金属离子的浓度超低，利用Perkin Elmer-PinAAcle 900T型原子吸收仪进行测试验证。本发明的有益效果是：发明了种经过简单设备提高了乙醇的纯度的方法及设备，加速了化学品发展，尤其是对推进电子级乙醇的生产及推广具有很大的意义。 |
