Не разбрах дали поста ти е насочен към мен, но за да не си в заблуждение ОК започва да отделя мравчена киселина, въглероден диоксид, въглероден оксид и вода още над 189 градуса.

“One of the problems with some vaporizers is that they get too hot too quickly and decompose, rather than evaporate the acid.” … “In the CRC Handbook of Chemistry and Physics we find that upon heating oxalic acid, the water of hydration boils off first, then at 315°F the oxalic acid starts to sublime (go directly from solid to vapor), and finally at 372°F any oxalic acid which has not yet sublimed decomposes to formic acid and carbon monoxide.” scientificbeekeeping.com
