Pentane is an organic compound that is a colourless and transparent liquid. Pentane smells like petroleum. It is less dense than water and does not dissolve in water. Also known as quintan and n-pentane. Pentane has two rotatable bonds. Below is a table of the formula for pentane.
Molecular Pentane Formula is C5H12
Primary formula is CH3(CH2)3CH3
The trend to use carbon dioxide is expected to continue in the future, but combustible organic compounds are used when the desired properties cannot be obtained. Expensive sub-fluorinated HFCs with relatively high GWP are only used where non-flammability is important. However, chlorine-containing compounds must be completely replaced.
Pentane Formula has been presented as a possible solution to find an efficient blowing agent that also meets environmental regulations, and years of experience with its use have shown that processing is safe as long as safety devices are fully implemented. Bayer’s PU machinery subsidiary, Hennecke GmbH, has developed a state-of-the-art system that monitors all critical control points along the processing chain to ensure safe production.
