Reaction of 1-butene with HCHO over H-ZSM-5. a Product yield as a function of residence time. Reaction condition: 1-butene 45 mbar, HCHO 0.32 mbar, H2O 22.5 mbar, 475 °C. b Reaction rates obtained for hydrogen transfer, Prins reaction (initial rates of formation of butane and pentadiene respectively under reaction conditions shown in a and methylation (represented by the DME/MeOH conversion rate at ~40% conversion shown in Fig. 1) on H-ZSM-5. Error bar represents the standard error of the reactions rates
