Hi Jim

Thermal fog for getting rid of smoke or smoke odors?
Well smoke is fine particals in air? how can anything react with these
fine particals, if you are talking about the odor then, an odor is a
sensation, not a chemical, so you cannot have a chemcal reaction. I
love when non chemist become sceptics and need a chemical recation
even though they wont understand it only for redimentry reactions such
as X+Y=Z.
These are costituents of Smoke Flavour, it was around our computer
database for years. Well it does depend on what has burnt etc.

Chromatogram of Liquid Smoke

From Cellulose Pyrolysis:

Acetic Acid
Formic acid
Maltol
Methyl cyclopenenolone
Ethylcyclpentenolone
Dimethylcyclopentenolones
Furfural
5-Hydroxymethylfurfural

From Lignin Pyrolysis:

Phenol
ortho, meta and para Cresols
Guaiacol
4-Methylguaiacol
4-Ethylguaiacol
4-Propylguaiacol
Pyrocatechol
Trimethylphenols
Vanillin
4-(2-Propio)-vanillone
4-(1-Propio)-vanillone
Acetovanillone
2,4,5-Trimethylbenzaldehyde
4-Hydroxyacetophenone
Eugenol
cis & trans-Isoeugenol
2,6-Dimethoxyphenol (Syringol)
4-Methylsyringol
4-Ethylsyringol
4-Propylsyringol
4-Acetosyringol
4-(2-Propio)-syringol
4-(1-Propio)-syringol
cis & trans-4-(1-Propenyl)-syringol
4-(2-Propenyl)-syringol
Syringaldehyde
               
Alot of the components above are large organic molecules which "stick
around" for along time and stick to things whith the smoke particals
above. So the above would prove that you need a number of components
to add to the above components to react. Since there are alot of
Oganic components, and you are using a thermal fogger, if possible you
could use an orgainic essential oil blend and surfactants. I know of
one company that has developed odorless essential oils and surfactant
blends which they have said reduce smoke odors utilising foging.
Essential oils have functional groups and surfactants, with the help
of the essential oils solublise the organic ingredients above into
water to be ''Washed away''.I can try and retrieve the info
