[Chemical Knowledge]：The Difference and Application of Anhydrous Methanol and Aqueous Methanol

Read： 585 Time：18months ago Source：Transform the World with Simplicity

Anhydrous methanol refers to methanol with high purity and no moisture, while methanol with water refers to methanol containing a certain amount of moisture. There are some differences in properties, preparation methods and applications. The main difference between

anhydrous methanol and aqueous methanol is its water content. The water content of anhydrous methanol is very low, usually less than 0.05%, while the water content of water methanol is higher, which can be as high as 1%-2%. This distinction is very important in certain areas of application. Anhydrous methanol acts as a solvent, catalyst, or intermediate in certain chemical reactions because the presence of water may interfere with these reactions. On the other hand, water methanol plays an important role in lubrication, dissolution and storage in some chemical synthesis and biological engineering. The preparation method of

anhydrous methanol is complicated. Common methods for the preparation of anhydrous methanol are distillation, drying and adsorption. Anhydrous methanol usually requires multiple purification and drying steps to achieve high purity. In contrast, the preparation of aqueous methanol is relatively simple and generally requires only distillation or other simple separation techniques.

anhydrous methanol and aqueous methanol have different applications in different fields. Anhydrous methanol is widely used in organic synthesis, catalytic reaction and preparation of high purity compounds. Water methanol is more commonly used in biochemistry, fuel cells and solvent preparation. Anhydrous methanol has high stability and low impurity content, and is suitable for processes that require high purity. And water methanol is more common, the price is lower, more suitable for some less harsh process.

In general, there are differences between anhydrous methanol and aqueous methanol in terms of water content, preparation methods and applications. According to the needs of different fields, choosing the right type of methanol is very important to achieve the best results. There are many application fields of anhydrous methanol and water methanol. With the continuous progress of science and technology and the continuous growth of demand in the future, the application prospects of these two kinds of methanol will be broader.
