摘要：NOVELTY - A process for preparing C2-C3 diol includes such steps as using the absorption liquid containing vinyl carbonate or allyl carbonate and ethanediol or propanediol to absorb the epoxy ethane (or propane) generated by oxidizing ethene (or propene) and CO2, catalytic esterifying reaction between epoxy ethene (or propane) and CO2 to generate vinyl (or allyl) carbonate, using part of vinyl (or allyl) carbonate as said absorption liquid, and catalytic hydrolyzing the rest to obtain high-purity ethandiol (or propanediol) and CO2.
