Methanol is synthesized from carbon monoxide and hydrogen (H2) in a catalytic reactor. CO + 2H2 → CH3OH The fresh feed to the process contains 32.0% mol of CO, 64% of H2 and 4% N2. This stream is mixed with a recirculation stream at a ratio of 5 mol recirculation / 1 mol fresh feed to the process. The mixture of these streams forms the feed stream to the reactor, which contains 13.0 mol% of N2. Low conversion is achieved...

IlI. Preparation of Synthetic Eugenol (10 pts) Eugenol, the main component of clove oil, can be prepared from heating 2-allyl guaiacol (in the absence of oxygen) to temperatures>205 °C. In practice, however, it is most cost effective to extract eugenol from cloves, its natural source. Given a weight percentage of eugenol in cloves at-15%, calculate the minimum mass of cloves one needs to obtain 1.00 g of eugenol as product? Report your answer below. Show your...
