Is toluene the same as acetone?

As nouns the difference between acetone and toluene is that acetone is acetone while toluene is toluene (liquid hydrocarbon).

Is toluene hazardous?

Products containing toluene can produce dangerous fumes which can cause nausea, headaches, unconsciousness, and even death if inhaled.

What is toluene used for?

Toluene is found naturally in crude oil, and is used in oil refining and the manufacturing of paints, lacquers, explosives (TNT) and glues. In homes, toluene

What does toluene dissolve?
