Is xylene the same as acetone?

Xylene is an organic compound having the chemical formula (CH3)2C6H4 while Acetone is an organic compound having the chemical formula (CH3)2CO. The key difference between xylene and acetone is that xylene is a cheap and less toxic solvent, whereas acetone is an expensive and more toxic solvent.

What does xylene dissolve?

In keeping with the general rule of thumb that like dissolves like, however, xylene is very good at dissolving other oily compounds that are poorly soluble in water. This makes it an excellent solvent for hydrocarbons and many hydrophobic or water-insoluble compounds like greases and various pesticides and herbicides.

Can I use xylene to thin polyurethane?

Thinning. Xylol paint thinner can be used for oil-based paints or stains, lacquers, polyurethanes, epoxies, oil finishes, enamels, varnishes and alkyd resins — but only when the coating manufacturer recommends it as an approved thinner.

What is the strongest solvent?

As per the general information floating around in the web and the details given in some of the books water is the strongest solvent amongst others. It is also sometimes called the “universal solvent” as it can basically dissolve most of the substances than any other liquid. Water is a good solvent due to its polarity.
