WebThe most prominent infrared absorption lines of ethanol The most distinct feature in the infrared spectrum of alcohols is the broad absorption band centred around wavenumbers 3400 to 3230 cm -1 due to O-H stretching vibrations, but broadened by intermolecular hydrogen bonding (diagrams below). WebThe methane and methanol as coolant, how would you propose that would work in this process? Methane is going to be a dissolved gas in water so it can’t absorb heat through condensation or any other phase transition. If it was hotter then the water could be partially evaporated and a cooling equilibrium established (in part) perhaps.
