Description
(一)技术领域
本实用新型涉及一种超净高纯级无水乙醇提取装置,属于电子化学品生产设备技术领域。
(二)背景技术
无水乙醇在电子化学品领域,作为去油剂使用。市售的无水乙醇一般只能达到99.5%的纯度,而用于微电子领域的无水乙醇纯度需要达到99.8%以上,这就需要对其进一步的浓缩提纯。要进一步的浓缩,继续用普通蒸馏的方法是无法完成的,因为此时,酒精和水形成了恒沸物(对应的恒沸温度为78.15℃),难以用普通蒸馏的方法分离开来,不能满足微电子领域使用要求。
(三)发明内容
本实用新型的目的在于克服上述不足,提供一种能生产纯度达到99.8%以上、可满足微电子领域使用要求的超净高纯级无水乙醇提取装置。
本实用新型的目的是这样实现的:一种超净高纯级无水乙醇提取装置,其特征在于:它包括原料罐、蒸馏塔、冷凝器、干燥器、过滤器和成品罐;
所述原料罐出口与蒸馏塔进口相连,所述蒸馏塔顶端出口与冷凝器进口相连,所述冷凝器出口与干燥器相连,所述干燥器出口管线分为两路,一路通过回流管与蒸馏塔上方进口相连,另一路与过滤器进口相连,所述过滤器出口与成品罐相连。
本实用新型的有益效果是:
本实用新型超净高纯级无水乙醇提取装置,破坏了酒精和水形成的恒沸物体系,通过蒸馏装置将水分蒸发出,通过干燥器吸收水分,然后经过过滤,得到纯度达到99.8%以上的超净高纯级无水乙醇,可满足微电子领域使用要求。
(四)附图说明
图1为本实用新型超净高纯级无水乙醇提取装置的结构示意图。
其中:
原料罐1、蒸馏塔2、冷凝器3、干燥器4、过滤器5、成品罐6、回流管7。
(五)具体实施方式
参见图1,本实用新型涉及的一种超净高纯级无水乙醇提取装置,主要由原料罐1、蒸馏塔2、冷凝器3、干燥器4、过滤器5和成品罐6组成;
所述原料罐1出口与蒸馏塔2进口相连,所述蒸馏塔2顶端出口与冷凝器3进口相连,所述冷凝器3出口与干燥器4相连,所述干燥器4出口管线分为两路,一路通过回流管7与蒸馏塔2上方进口相连,另一路与过滤器5进口相连,所述过滤器5出口与成品罐6相连。
使用时,将少量乙醇、镁和碘加入蒸馏塔中,待镁溶解生成醇镁后,再加入乙醇,加热回流,然后蒸馏提纯过滤得成品。
