摘要：
A method of producing dimethoxymethane oligomers (DMMn), the method comprising: reacting a formaldehyde source and dimethoxymethane monomer (DMM1) in the presence of an acidic catalyst to produce a reaction effluent comprising DMMn and unreacted DMM1; and separating, from the reaction effluent, DMM1-2 including unreacted DMM1 and DMMn having a chain length n equal to 2 (DMM2), dimethoxymethane oligomers having a chain length n in the range of from 2-5 (DMM2-5), dimethoxymethane oligomers having a chain length n of ≥5 (DMM5+), or a combination thereof, wherein the separating comprises distillation in the presence of at least one alcohol, a distillate fuel, or both.
