11. The ethane subsequently undergoes dehydrogenation to form ethylene ( ). 12. It would be a triple alcohol with the ethane backbone. 13. Larger hydrocarbons such as ethane and propane produce bilayer coatings. 14. Natural gas liquids include propane, butane and ethane . 15. It was unclear what set the ethane on fire. 16. Nevertheless, the propylene output rates from ethane -fed crackers are negligible. 17. The chemistry of ethane involves chiefly free radical reactions. 18. Ethane is most efficiently separated from methane by liquefying it at cryogenic temperatures.19. Experimentally, ethane is under investigation as a feedstock for other commodity chemicals. 20. Some additional precautions are necessary where ethane is stored as a cryogenic liquid.
