I want to lay my hands on some dichloromethane, mainly for solvent welding of acrylic and plastics, but for other stuff, too (eg. trying extraction of caffeine from coffee beans). Any ideas where I can get it? Anyone know any chemical suppliers that are OK to deal with when dealing with the public? I don't really believe it's a chemical of concern at all with regards to drugs and the like, so I figure it's worth trying if I can find a reasonable chemical supplier.
