When I was working recently with plumbers we had much discussion about gas fitting and which compounds can be plumbed. Plumbers are also frequently using a flame for welding and soldering. One such product that is easy to carry is a small yellow bottle that the plumbers know only as MAPP gas. I at first wondered if it were propane, butane or acetylene. I later learned that it was none of these and in fact propylene.
Below is a list of non-alkane compounds that I believe can be plumbed. The ones with BP of 15–35 °C will probably need a heated pipe.
