ChemiSTEAM 2020: Sublimation of VO(acac)2

CELEBRATE

In this synthesis, we attempted a sublimation of our crude product as an alternative to the usual purification of vanadyl acetylacetonate that involves the recrystallization from dichloromethane and ether. This was a conscious effort to change the synthesis towards methodology that incorporated principles of green chemistry. By making this switch, we tried to make a safer and more efficient synthesis that avoided using dangerous solvents and reduced the waste. I captured this close-up of the sublimed crystals in their vibrant blue and chaotic crystalline texture that showcases this attempt.
