SWIM is thinking about how to obtain a little Formaldehyde - if he got for example a solution of 13,0 g Formaldehyd, 3,6 g Glyoxal, 3,2 g Glutaral per 100g, how could the Formaldehyd be separated from the two other ingredients - destillation is the only thing SWIM can think of, but if formaldehyde has a boiling point of around minus 20 degree of Celsius ...
(bp Glutaral 72C, Glyoxal 51C , as far as i know)
Has anyone experiences with something like this (or maybe any idea or suggestion)?
Thanks
