无水氯化钙为什么能够作为干燥剂使用呢

  众所周知,无水氯化钙是理想的干燥剂,在实验中,常常被用来干燥液体和气体,不少人的心中都有疑惑,无水氯化钙为什么能够作为干燥剂使用呢?接下来小编就带您前去探索一下。
  干燥剂的基本原理,说白了就是可以与水发生反应,可以将水分子变成可沉淀和吸附的固体,从而与想要干燥的物质分离。无水氯化钙进行干燥反应的化学方程式如下所示:CaCl2+2H2O=CaCl2·2H2O,从中就可以看出,无水氯化钙是可以与水反应,形成不同的结晶化合物,从而与要提取的物质分离。它可以结合水分子形成五水氯化钙,化学式表示为CaCL2(H2O)5,这样在干燥的时候,无水氯化钙就可以轻松脱水,再使用四五十度的温度进行烘干,可以实现重复利用。

  当然,要注意无水氯化钙也不是任何的气体都可以干燥的,像乙醇、氨气或者部分分脂类等有机物,无水氯化钙会和它们进行反应形成络合物。不能实现干燥的效果。

  As is known to all, anhydrous calcium chloride is an ideal desiccant, in the experiments, liquids and gases are often used to dry, the heart of a lot of people have doubts, why anhydrous calcium chloride can be used as a desiccant? The small make up take you to explore.
  The basic principle of desiccant, namely can react with water, water molecules become available precipitation and adsorption can be solid, thus separated from want dry matter. Anhydrous calcium chloride response of dry chemical equations as follows: CaCl2 + 2 h2o = CaCl2 · 2 h2o, from which you can see, anhydrous calcium chloride can react with water and form different crystalline compound, and to extract the material separation. It can combined water molecules to form five water calcium chloride, chemical formula expressed by CaCL2 (H2O) 5, so when dry, anhydrous calcium chloride can easily dehydration, drying temperature to use 40 to 50 degrees, can be reused.
  Attention should be paid to anhydrous calcium chloride is not, of course, any gas can be dry, like organic compounds such as ethanol and ammonia or part points the lipid, anhydrous calcium chloride complex was formed by reaction with them. Can't achieve the effect of drying.
