Propane was first synthesized by the French chemist Marcellin Berthelot in 1857 during his researches on hydrogenation. Berthelot made propane by heating propylene dibromide (C 3 H 6 Br 2) with potassium iodide and water. [9] [10]: p. 9, §1.1 [11] Propane was found dissolved in Pennsylvanian light crude oil by Edmund Ronalds in 1864.
Frederick Winsor was the key player behind the creation of the first gas utility, the London-based Gas Light and Coke Company, incorporated by royal charter in April 1812.

Propane is the third most widely used motor fuel in the world. 2013 estimates are that over 24.9 million vehicles are fueled by propane gas worldwide.
Mean benzene emissions from gas and propane burners on high and ovens set to 350 °F ranged from 2.8 to 6.5 μg min–1, 10 to 25 times higher than emissions from electric coil and radiant alternatives. [1] Some high-end cooktop models provide higher range of heat and heavy-duty burners that can go up to 6 kilowatts (20,000 BTU/h) or even more.
Analysis of sample of propane that can be traced back to Snelling has been shown to contain 0.062 mole% methane, 23.44 mole% ethane, 57.366 mole% propane, 7.127 mole% isobutane, 11.957 mole% butane, and 0.044 mole% isopentane. [10] In 1913, Snelling sold his propane patent for $50,000 to Frank Phillips, the founder of Phillips Petroleum Company ...
