WebPerchloroethylene‘s non-flammability and low vapor pressure make it an effective cold (room temperature) metal cleaner, when used in compliance with applicable regulatory requirements. Its low vapor pressure contributes to reduced emissions from cold cleaning operations where it is employed. WebAlthough all these alkanes are combustible and can burn in oxygen, the more carbon atoms there are or the larger the molecule, the stronger the van der Waals forces of attraction are. As a result, more energy is required to vaporize these larger or longer molecules. WebAlkanes are not very reactive and have little biological activity; all alkanes are colorless and odorless non-polar compounds. The relative weak London dispersion forces of alkanes result in gaseous substances for short carbon chains, volatile liquids with densities around 0.7 g/mL for moderate carbon chains, and solids for long carbon chains. danish lounge chair cup
