Resumo (PT): This article reports a study to increase the overall greenness of chemical syntheses for first-year university laboratories. The separate evaluation of the microgreenness of the three stages of synthesis (reaction, isolation and purification) using the Green Star (GS) was implemented and their respective contribution to overall greenness was investigated for two examples: syntheses of cobalt (III) tris(acetylacetonate) and potassium nitrilosulfonate. Results showed that the post-reaction (work-up) steps are the most problematic for overall greenness. Greenness optimization can be achieved by combining the greenest procedures for each step obtained from different protocols available in the literature.
