摘要:
The present invention relates to a method for producing polyoxymethylene dimethyl ether by introducing a formaldehyde source and at least one compound of the formula (I) H3C—O—R (I) where R is H or —(CH2O)x—CH3 with x being 0 or 1 as reactants into a reactive distillation unit and reacting them to give polyoxymethylene dimethyl ether, wherein the method produces polyoxymethylene dimethyl ether exclusively in the reactive distillation unit.
