ELi5- Does gas that has been reduced from evaporation become more potent?

In: Chemistry

Gasoline?

No, it doesn’t become more potent in any way. The gasoline is what is evaporating, so you just lose some to the air and nothing else changes.

Do you mean Distilling? If not that then it doesn’t affect the product. Distilling is done where you only boil off one liquid at a time and that concentrates/ makes them more potent.

Unfortunately, the stuff that evaporates out of gasoline is also the stuff that makes it potent.

In events like the recent hoarding of gasoline storing it in unsealed containers, the gas loses enough potency to be useless within a few weeks. Stored in sealed containers (limiting loss) it can last many months. Stored in sealed containers with a gas stabilizer can last for even longer, the stabilizer reduces the potency but it harms it less than the time on the shelf would.
