Reaktionsschritte

A 50 cm long, 5 cm diameter water-jacketted reactor (Reactor C) was charged with 1 liter of Dowex MSA 1 strong base resin. The resin was treated in sequence with 2000 ml of ethanol, 2000 ml of water, 3800 ml of 4 weight percent aqueous sodium hydroxide, and 5000 ml of methanol-ethanol mixture. This reactor was used to react mixtures containing ethyl acrylate and both methanol and ethanol to produce mixtures of ethyl 3-methoxypropanoate, methyl 3-ethoxypropanoate, ethyl 3-ethoxypropanoate and methyl 3-methoxypropanoate. In each run about 7.5 liters of a feed solution containing the components identified in Table IV was used. There was no problem of ethyl acrylate breakthrough at the end of each run. The mixture was recovered by distillation to remove the alcohols.
