A convenient preparation of ethoxymethoxymethane and its effect on the solubility of methanol/gasoline blends

Ethoxymethxoymethane (EMM) was conveniently prepared by acetalization of aqueous formaldehyde with methanol and ethanol in a batch reactive distillation mode using a cation-exchange resin catalyst for the first time. EMM was found to be a significant cosolvent of methanol/gasoline blends.
