如何为您的蒸馏纯化实验选择旋转蒸发仪?



旋转蒸发仪是在实验室提取用于从样品蒸发的溶剂的高效和温和蒸馏的设备。旋转蒸发通常用于方便地将“低沸点”溶剂(例如丁烷或乙醇)与在室温和压力下为固体的化合物分离。但是,小心地施加减压可以从样品中除去溶剂而不会降解产品。降低压力可通过降低沸腾瓶中各组分的沸点来加快过程,从而实现可能的**低温度蒸馏。旋转的10,000毫升沸腾烧瓶向侧面喷射液体,迫使更多的液体暴露于表面积并有效地传递更多热量。减压和高效传热的结合使该蒸馏设备非常适合快速工业分离。

当该系统与大气相连时,可以移出蒸馏瓶和液体接收瓶,并转移溶剂。当系统与减压泵连接时,应缩小系统尺寸。压力状态。使用时,先降压,然后启动电动机旋转蒸馏瓶。**后,**先停止机器,然后通过大气以防止蒸馏瓶在旋转过程中掉落。旋转蒸发器作为蒸馏的热源,可与循环水式多功能真空泵,隔膜真空泵,低温循环(真空)泵,循环冷却器,恒温循环器,低温组合使用冷却剂循环泵等形成系统装置。

 操作旋转蒸发仪时,您可能经常遇到以下问题:

1.ZHENGFASHIJIESHOULVDISHIHAODE。

2.真空泵被腐蚀。
 
3.有害气体逸出。
 
4.突然的溶剂碰撞。
 
旋转蒸发仪系统的真空度高于正常水平是可能的原因。如果真空度太高,将导致溶剂蒸汽温度太低,因此无法有效收集。需要释放真空,但是如果真空度太低,还会发生其他问题。

如何避免这些问题?
