Propane appliances include space heaters, furnaces, water heaters, cooktops, ovens, clothes dryers and pool heaters. The information is aggregated from the data coming from REACH substance registrations provided by industry. As the steady-state TOF of propene oligomerization to C 4 –C 9 olefins at 473–533 K over close protons exceeds 2–10 fold (with increasing Si/Al) those over isolated protons, the release of olefins from alkoxides is suggested to be an important reaction step. In contrast, propane boils at -42°C becoming gas vapour. Propane tank sizes and volumes vary, based on application and demand. 3. In the above processes, propene is prepared with addition of at least equimolar amounts of ethene.
