A CHEAP AND EFFICIENT PHOTOCHEMICAL REACTOR FOR CHEMICAL EXPERIMENTS. In this work, we present an efficient and inexpensive device for undergraduate chemistry classes aimed at teaching and learning the photolytic synthesis concepts. A photochemical reactor was tested for the synthesis of the organometallic compound enneacarbonyldiiron from iron pentacarbonyl in acetic acid, and its formation evidenced by FTIR analysis. Although similar devices have been described in other studies, none of these offered the simplicity, low cost, class-compatible reaction times and good yields afforded by the procedure reported herein.
Keywords: photochemistry; reactor; enneacarbonyldiiron.
