These do not equate to fluxes.  They are thin (monomolecular in some cases)
protective coatings that prevent the copper from oxidizing.  They are
removed by the heat of the soldering process (or alcohol).  Fluxes on the
other hand become active at elevated temperatures and actually reduce or
remove oxides on the copper surface.

I'm a rusty on the actual chemistry.  I certain there are others who can
fill us in on that aspect if needed.

Earl, I don't work with fluxes, I can't answer this question.

Jana,

I too thank you for the input. Do these chemistries equate in some way to
"fluxes?"

Earl
