Azeotropic distillation to extract pure methylbenzene (TOLUENE) from BRUSH CLEANER

My next video on getting methylbenzene (toluene) will NOT be an extraction but a SYNTHESIS. I am actually in the middle of the experiment right now where i take mixed xylenes and oxidize with DILUTE nitric acid by refluxing. Now that only makes toluic acid(methyl benzoic acid). But just like when you do a soda lime decarboxylation with benzoic acid to make benzene you can do the same with toluic acid but instead of making benzene you will make methylbenzene (toluene).................the reason why........So far i tried to distill out some methylbenzene (toluene) out of auto parts cleaner and then i tried it with the azeotrope method to extract because my yield was so low but i still got the same low yield. So i tried this brush cleaner in this video and i used the azeotrope way to extract because it gives a more pure product but you add so much alcohol i do not know if it is worth it. What i learned is that they do not put much toluene in products near my area. Use fume hood ..gloves...goggles if you do this experiment. The chemicals are all carcinogenic and flammable
