Question:
Is there a substitute for aerosol sprays?
DuPont's Freon (TM)-11 harms the atmosphere and oxygen does not. Could we use oxygen instead?



Replies:
Compressed carbon dioxide has been used as a propellant in aerosol sprays, oxygen, however, is much too explosive when compressed and would not be a go good candidate for aerosol sprays. Finding replacements for compressed gas propellants has not been a big problem, however, finding replacements of for the freons used in air conditioners has been more difficult. As you may have noticed from the "green" neon car commercials a replacement has been found although it is more expensive and I have heard that it cannot be used as a replacement gas in home window air conditioners.
