Methanol to formaldehyde via chromyl chloride

nscheffield - 10-2-2016 at 05:42

I was wondering if it would be possible to partially oxidize methanol with chromyl chloride to formaldehyde. I am pretty sure that chromyl chloride will stop at the aldehyde stage like it does with toluene to benzaldehyde. I am worried to try it my self yet because 1) reactions like this have back fired on me in the past 2) Chromyl chloride is not a reagent i want to waste. any input would be greatly appreciated.

I don't know if the reaction works, but you can also make Formaldehyde from 1,3,5-Trioxane found in Military camping tablets. Combining it in acidic solution will create Formaldehyde, that can be distilled off (bubbled through H2O) to make formalin.
