Methanol is primarily converted to formaldehyde, which is widely used in many areas, especially polymers. The conversion entails oxidation: 2 CH 3 OH + O 2 → 2 CH 2 O + 2 H 2 O. Acetic acid can be produced from methanol. The Cativa process converts methanol into acetic acid. [35] Methanol and isobutene are combined to give methyl tert-butyl ...
Since methanol vapor is heavier than air, it will linger close to the ground or in a pit unless there is good ventilation, and if the concentration of methanol is above 6.7% in the air it can be lit by a spark and will explode above 54 F / 12 C. Once ablaze, an undiluted methanol fire gives off very little visible light, making it potentially ...

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:
It is useful in comparing fuels where condensation of the combustion products is impractical, or heat at a temperature below 150 °C (302 °F) cannot be put to use. One definition of lower heating value, adopted by the American Petroleum Institute (API), uses a reference temperature of 60 °F (15 + 5 ⁄ 9 °C).
A Assuming an altitude of 194 metres above mean sea level (the worldwide median altitude of human habitation), an indoor temperature of 23 °C, a dewpoint of 9 °C (40.85% relative humidity), and 760 mmHg sea level–corrected barometric pressure (molar water vapor content = 1.16%).
In the absence of nucleators water can exist as a supercooled liquid down to −48.3 °C (−54.9 °F; 224.8 K) before freezing. [4] The metal with the highest melting point is tungsten, at 3,414 °C (6,177 °F; 3,687 K); [5] this property makes tungsten excellent for use as electrical filaments in incandescent lamps.
The Fahrenheit scale (/ ˈ f æ r ə n h aɪ t, ˈ f ɑː r-/) is a temperature scale based on one proposed in 1724 by the European physicist Daniel Gabriel Fahrenheit (1686–1736). [1] It uses the degree Fahrenheit (symbol: °F ) as the unit.
