are xylene and toluene the same thing?
xylene is almost identical to toluene, it just has 1 more methyl group off the benzene ring. It is a mix of 1,2-dimethylbenzene, 1,3-dimethylbenzene, and 1,4-dimethylbenzene. Comparable to toluene, and is used as a thinner of paints when slower drying is required.
