What happens when methanol and ethylene glycol are added?
Shanghai simantai chemical technology co., ltd. friendly answer:

What is it for in the first place?

1, chemical reaction requires a catalyst, such as concentrated sulfuric acid (for dehydration), to produce ether. Of course, there are many kinds of ethers, including ethylene glycol ether, methyl ether, ethylene glycol monomethyl ether, ethylene glycol dimethyl ether and so on. Deep dehydration has other by-products.

2. There is no simple chemical reaction. If it is only mixed at room temperature, there is no catalyst. No simple chemical reaction will occur.

3. Simple physical state. When two substances are simply mixed, because of the high density of ethylene glycol and the low density of methanol, stratification will occur. Moreover, this stratification is a continuous process, that is, once the external disturbance energy stops, it will be stratified for a period of time, with more ethylene glycol in the lower part and more methanol in the upper part.

4. If used as an anti-freezing system. For example, the so-called "three-in-one liquid" on the market is a misunderstanding. The freezing resistance of ethylene glycol solution reaches -50℃, and the freezing resistance of methanol is even lower, reaching below -70℃. But each has its own disadvantages, such as high viscosity of ethylene glycol, volatile methanol and high toxicity. In fact, the purpose of mixing the two is to obtain a better antifreeze that can be used at -40℃. But from a usability point of view, yes. However, there are great security risks, and in fact, the shortcomings of the two are superimposed and more corrosive. It is corrosive to carbon steel, stainless steel and all kinds of copper.
