9. The boss is keen to generate the methoxide catalyst on site and has identified an available 2m³ agitated reactor. This process consists of feeding 270 kg a sodium metal pellets (Mw=23) in to 1.25 m³ methanol giving a final volume of methoxide solution of 1.5m³. This is considered very dangerous, and you are keen to have not more than 90 gr of Sodium metal in the vessel at any one time. You therefore suggest a fed batch process. Literature has the following information for the metoxide formation: 1 Na + HO-Me → NaOMe +H₂ (-RNa)=0.047 [Na] 2/3 in g/L.s with [Na] the concentration of sodium metal in g/L. Assuming a constant volume that gives a conservative estimate, you predict the minimum addition time of to be: a. 1.6 hr b. 3.8 hr c. 7.4 hr V d. 18 hr e. 43 hr f. 82 hr 13
