VINYL ACETATE HAVING LOW DEUTERIUM CONTENT

The present invention relates to processes for making vinyl acetate, based on methanol having a deuterium content below 90 ppm, comprising the step of reacting acetic acid with ethylene to give vinyl acetate, and to processes for making vinyl acetate, based on methanol having a deuterium content below 90 ppm, comprising the steps of reacting acetic anhydride with acetaldehyde to form ethyliden diacetate and reacting ethyliden diacetate to give vinyl acetate by thermal elimination of acetic acid, as well as to vinyl acetate having a deuterium content below 90 ppm, based on the total hydrogen content. The present invention further relates to a vinyl acetate having a natural abundance of carbon-14 from non-fossil resources, preferably from biomass, as well as to its use. The present invention also relates to a process for preparing alkoxylated compounds comprising ethylene oxide units and/or propylene oxide units, comprising the steps: (a) reacting hydrogen with carbon dioxide to form methanol, (b) converting the methanol from step (a) to ethene and/or propene, (c) reacting the ethene and/or propene from step (b) with oxygen or an oxidizing agent to form ethylene oxide and/or propylene oxide, and (d) reacting the ethylene oxide and/or propylene oxide with the at least one starter unit having Zerewitinoff active hydrogen atoms to form the alkoxylated compound, wherein the carbon dioxide in step (a) is at least in part captured from industrial flue gases or from air or from ocean water or other natural waters or obtained from biological processes; and the alkoxylated compounds obtainable by the process. The invention further relates to graft polymer based on ethylene oxide-comprising backbones being grafted with olefinically polymerizable monomers, preferably vinyl monomers, more preferably with a) vinyl esters or b) vinyllactams, wherein such graft polymer is at least partially based on hydrogen from non-fossil-based sources, wherein the molar share of deuterium is lower in such graft polymer than that in the identical chemical compound when derived solely from fossil-based sources.
