Here is a similar formula from the 67th edition of the CRC handbook. Note that the form of this formula as given is a fit to the Clausius–Clapeyron equation, which is a good theoretical starting point for calculating saturation vapor pressures:
The energy or temperature to induce release affects the cost of any chemical storage strategy. If the hydrogen is bound too weakly, the pressure needed for regeneration is high, thereby cancelling any energy savings. The target for onboard hydrogen fuel systems is roughly <100 °C for release and <700 bar for recharge (20–60 kJ/mol H 2). [13]
300 to 700 kPa 50–100 psi Typical water pressure of a municipal water supply in the US [59] 358 to 524 kPa: 52-76 psi Threshold of pain for objects outside the human body hitting it [60] 400 to 600 kPa 60–90 psi Carbon dioxide pressure in a champagne bottle [61] 520 kPa 75 psi Partial vapour pressure at the triple point of carbon dioxide [62]

This page contains tables of azeotrope data for various binary and ternary mixtures of solvents. The data include the composition of a mixture by weight (in binary azeotropes, when only one fraction is given, it is the fraction of the second component), the boiling point (b.p.) of a component, the boiling point of a mixture, and the specific gravity of the mixture.
That testimony, and pressure from The Indianapolis Star writer George Moore, led to the switch to alcohol fuel in 1965. Methanol was used by the CART circuit during its entire campaign (1979–2007). It is also used by many short track organizations, especially midget, sprint cars, and speedway bikes. Pure methanol was used by the IRL from 1996 ...
In 2007, China blended more than 1 billion US gallons (3,800,000 m 3) of methanol into fuel and will introduce methanol fuel standard by mid-2008. [49] M85, a mixture of 85% methanol and 15% gasoline can be used much like E85 sold in some gas stations today. Methanol from Supermarket as grill lighter fluid (Spain, 99 % methanol, colored blue)
According to Primus Green Energy, the STG+ process converts natural gas into 90+-octane gasoline at approximately 5 US gallons per million British thermal units (65 litres per megawatt-hour). [4] The energy content of gasoline is 120,000 to 125,000 British thermal units per US gallon (9.3 to 9.7 kilowatt-hours per litre), making this process ...
