Toluene is MUCH better than acetone for dissolving sulphur. Sulphur only dissolves in tiny amounts in acetone, but it hardly is worth to mention. Besides that, acetone is more volatile and more flammable. I also did the experiment with acetone, but it simply sucks.
I also did the experiment with ligroin (a mix of low-boiling alkanes, 40-60 degrees centigrade). Sulphur does not dissolve in that at any appreciable amounts. I expect it to be the same with butane.
Heating the toluene is not that dangerous in the way I did this.
I boiled water and then immersed the test tube with sulphur and toluene in the hot water. If you want to do the experiment on a larger scale, then you have to use an electrical water boiler and put your beaker with toluene and sulphur in that. Do NOT use open fire with this experiment.
Making CS2 yourself is VERY mad. CS2 is extremely flammable. Vapor of CS2, going over hot (boiling) water may be ignited already. Acetone, butane and toluene are childrens toys, compared to CS2. It is toxic like hell and flammable like hell.

After you have read this, then you'll understand that making CS2 yourself is not feasible, unless you have a really well-equipped home-lab.
