How do you get rid of butanoic acid smell?

Answer 1

Ventilation and time. Lots and lots of scented soap might help.

(For the uninitiated, butanoic acid smells like rancid butter. Another description would be "vomit.")

Reacting it with methanol produces a rather pleasant pineapple-like scent, but since this is an equilibrium, to drive it toward the ester requires a powerful dehydrating agent like concentrated sulfuric acid. This may not be feasible, depending on what the butanoic acid is on.

Answer 2

To get rid of butanoic acid smell, you can try using baking soda to absorb the odor, ventilating the area by opening windows or using fans, and cleaning the affected area with a mixture of vinegar and water. Additionally, using odor neutralizers or air purifiers can help to eliminate the smell.
