Does crude methanol contain isopropanol? In a 500,000-ton coal-to-methanol production process, analysis of the crude methanol revealed the presence of isopropanol, in amounts higher than those of ethanol. The analysis report shows that the total ethanol content is 100 ppm, while the isopropanol content reaches 400 ppm.
It is an isomer of n-propanol, CH3-CH2-CH2OH. Appearance and properties: Colorless transparent liquid with an odor similar to a mixture of ethanol and propanol. Melting point (°C): -88.5 Boiling point (°C): 82.3 Relative density (water=1): 0.79 Relative vapor density (air=1): 2.07 Saturated vapor pressure (kPa): 4.40 (20°C) Heat of combustion (kJ/mol): 1984.7 Critical temperature (°C): 275.2 Critical pressure (MPa): 4.76 Logarithm of the octanol/water partition coefficient:
Isopropanol can also be produced through propylene hydrogenation
