Yes. It doesnt work the way you think. When you mix chemicals together and then boil, the result isn’t that simple.

Think of it this way: ethanol boils at 78.5. Water at 100. But when I’m distilling, the first stuff out of the still is coming out at like 80/20 ethanol to water, long before I’m near 100C. The later stuff still has some ethanol in it, even as I near 100C. (You can easily measure while distilling.)

So why would it be surprising that methanol behaved that way as well?
