Experiment 3: Synthesis of Co(acac-NO2)3 Introduction In this lab‚ Co(acac·NO2)3 is synthesized using the Co(acac)3 complex produced in Experiment 2. The Co(acac)3 complex is used as a reagent instead of acacH because acacH cannot be directly converted to 3-nitroacetylacetone. Since Co(acac)3 is not stable in HNO3‚ Cu(NO3)2 and acetic anhydride are used in this reaction to produce the final product‚ Co(acac·NO2)3. The exact mechanism of the reaction is unknown‚ however

Synthesis of Aspirin and Tylenol Kyla Wykoff Abstract Aspirin and Tylenol were synthesized by means of crystallization‚ recrystallization‚ and melting point determination. Synthesis produced significantly high percent yields for aspirin‚ however‚ produced extremely low and impure percent yields for Tylenol. A second group was also used to compare results and errors‚ in which they too were also producing extremely low percent yields of Tylenol. Therefore‚ error was based on the specific protocol
