Will combustion occur when "(paint)thinner" comes into contact with water?

You should really see what the painthinner consists of!

I think it shouldn't react technically since it is a solvent and thus would just dissolve the water as they are both polar.

"dissolve the water" is a very bad choice of words.

Isn't paint thinner largely toluene?

Sometimes. Sometimes it is acetone as well. Or "Mineral Spirits". As we have to clean a lot of glassware in our lab, we actually by bulk fairly pure acetone from Sherwin William to do the bulk of cleaning with that, and rinse that acetone off in the end with more pure acetone from Fisher.

5 gallons of fairly pure acetone from Sherwin William (we were curious and did some testing of it) cost about what 4 liters of HPLC grade acetone from Fisher costs! For bulk cleaning, it is a no brainer.

Paint thinner are organic solvents and I dont think they are reactive enough for any combustion reaction with water.

*****solvents are generally inert ****Are  you aware of this property ?

Not at all.



Though I think the original poster might be trying to ask, "if I mix a flammable organic solvent with water, can it still burn?". The answer to that, if it is the question, yes.

The answer is yes or no depending on what the solvent is and what the proportions of solvent and water are.
