OPTIM™ Synthetic Glycerine - Vapor Pressure and Boiling Point

Vapor pressures of pure glycerine are calculated by extrapolating from partial pressures of solutions to the point where the partial pressure equals the total pressure. These values are estimated to be accurate to about one percent. Volatility data, including boiling point or vapor pressure, for various glycerine-water solutions, are available.
