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

there would still be impurities present leading to a decreased yield in pure crystals formed. Some crystals may have been lost in the Buchner funnel or when transferring from the funnel to the beaker. Some crystals may have been lost when transferred from the filter paper to the beaker before obtaining the mass of the crystals. I may have also used too much solvent to the acenatilide leading to a smaller recovery of crystals. There may have also been impurities present in the flask used to heat the

ZERO SCORE Paragraph 1 There are three phases whereby each has a different crystal structure at three different temperatures. At room temperature (298K)‚ Phase III is present whereby Cs3H(SeO4)2 has a crystal structure of a monoclinic with a space group of C2/m. At 400K‚ Phase II is present whereby Cs3H(SeO4)2 has a crystal structure of a monoclinic-A2/a symmetry. At 470K‚ Phase I is present whereby Cs3H(SeO4)2 has a crystal structure of a trigonal with a space group of R3-m. In Phase III‚ as we can
