Mean-field dynamics of CRN 1 (formose reaction) in CSTR. The reaction rate constants are ω1=1,ω2=0.7 and ω3=0.4. a The initial condition is ξa=(n0,n1,n2,n3,n4)=(80,5,5,5,5), meaning that there are always N=100 mol molecules in the solution and thus the total volume of the solution in the tank is ν×N=1.8 L. The inflow is fa=(f0,f1,f2,f3,f4)=(8,2,0,0,0), meaning that F=10 mol fresh solution flows into the tank per second, 80% (=f0/F) of which is the solvent molecule \(\overline {0}\) and 20% of which is molecule \(\overline {1}\). It also means that per second, 10% (=F/N) of the solution in the tank is replaced. After the transient period (t>50), the outflow is \(\boldsymbol {f^{\prime }}_{\boldsymbol {\xi }_{a}, \boldsymbol {f}_{a}} \doteq (91.5, 0.7, 3.0, 3.2, 1.7)\). b The initial condition is ξ0=(100,0,0,0,0), and the inflow is fa, as the same as in (a). After the transient period, the outflow is \(\boldsymbol {f^{\prime }}_{\boldsymbol {\xi }_0, \boldsymbol {f}_{a}} = (8, 2, 0, 0, 0)\)
