| titleOfInvention | Preparation method of lithium phosphate catalyst and application thereof in catalyzing propylene oxide isomerization |
| abstract | The invention discloses a preparation method of a lithium phosphate catalyst. The preparation method comprises the steps of respectively dissolving Na3PO4.12H2O and LiOH.H2O, and simultaneously pouring the Na3PO4.12H2O and the LiOH.H2O into a container under water bath and stirring to be uniform, wherein pouring is completed in 30s; carrying out stirring reaction on the Na3PO4.12H2O and the LiOH.H2O for 60-120 minutes, then standing for ageing, washing a reaction product until the pH value is 11.5, and reducing pressure and carrying out suction filtration so as to obtain a filter cake; placing the obtained filter cake in the last step into a vacuum drying chamber to dry for 6h, and calcining the filter cake in a muffle furnace so as to obtain the lithium phosphate catalyst. Compared with the prior art, the preparation method provided by the invention has the advantages that the adding speed of Li3PO4 provided by the invention is controlled through adopting a combining-adding type charging mode, meanwhile, the proper ageing time is controlled, the lithium phosphate with high catalytic efficiency is obtained through vacuum drying and low temperature calcination, the product is white and is hollow and spherical, and the average particle diameter is 700nm; the technical process of the preparation method is short, the catalysis propylene oxide conversion rate is high and can achieve about 90%-95%, and meanwhile, the allyl alcohol selectivity also keeps to be 91%-96%. |
