CHCOCHCOCH H.COH + CIH, CHCOCH, 4. (25 p) A PFR operating isothermally at 773 K is used to conduct the following reaction: CH,COCHCOCH, = CH.COH + CH, CHCOCH, CH methylacetoxypropionate acetie acid methyl acrylate If a feed of pure methylacetoxypropionate enters at 5 atm and at a flow rate of 0.193 ft/s, what length of pipe with a cross-sectional area of 0.0388 ft is necessary for the reaction to achieve 90 percent conversion. Data: k = 7.8 x 10 exp(-19,200/T) s
