An inlet stream consisting of 20% CH, and 80% water is fed into a continuous evaporator. The substances after the reaction will pass through the condenser, knowing the condenser's output consists of two streams, the steam stream containing C, H, CH3OH and water; dong long consists of the remains of C2H, CHOH and water. The vapor leaving the condenser cell will be recirculated and mixed with the original inlet stream before entering the reaction cell. Let the reaction take place as follows:
