Embodiment 2
[0025] Put 600 grams of acidic ion exchange resin, 2,700 grams of paraformaldehyde, and 3,700 grams of methylal into the reactor respectively, and slowly heat to 150°C for 2 hours at a constant temperature, then pump the reaction liquid into the membrane separation dehydrator at 8 L / hr. The water in the reaction solution was removed and then returned to the reactor, and samples were taken from the reactor every 1 hour to analyze the composition of reactant grade products in the system. The results are shown in Table 2.
