Paragraph 0094-0120, (2021/07/28)
The invention discloses a method for preparing 1, 3-dihydric alcohol by taking olefin and methanol as raw materials through one-step reaction and a catalyst for the method. The method comprises the following steps: 1) adding a catalyst into a reactor, heating and reducing in a hydrogen-nitrogen mixed atmosphere, then cooling to 60-180 DEG C, and keeping the pressure in the reactor to be 0.5-8 MPa for reaction; 2) respectively introducing olefin and a methanol aqueous solution into the reactor for reaction, wherein the airspeed is 0.01-10h in terms of methanol; 3) enabling that the reaction product enters a product storage tank after condensation and gas-liquid separation; and 4) carrying out rectification separation on the reaction product obtained in the step 3) to obtain a 1, 3-dihydric alcohol product with the purity of more than 99%. The method provided by the invention has the advantages of low raw material cost, simple steps and continuous production.
Ruthenium-Catalyzed Synthesis of Cyclic and Linear Acetals by the Combined Utilization of CO2, H2, and Biomass Derived Diols

supporting information, p. 11412 - 11415 (2019/07/18)
Herein a transition-metal catalyst system for the selective synthesis of cyclic and linear acetals from the combined utilization of carbon dioxide, molecular hydrogen, and biomass derived diols is presented. Detailed investigations on the substrate scope enabled the selectivity of the reaction to be largely guided and demonstrated the possibility of integrating a broad variety of substrate molecules. This approach allowed a change between the favored formation of cyclic acetals and linear acetals, originating from the bridging of two diols with a carbon-dioxide based methylene unit. This new synthesis option paves the way to novel fuels, solvents, or polymer building blocks, by the recently established “bio-hybrid” approach of integrating renewable energy, carbon dioxide, and biomass in a direct catalytic transformation.
