| Abstract: | Pentaerythritol and dipentaerythritol were synthesized using formaldehyde,acetaldehyde and NaOH as the raw materials.The influence of the mol ratio of the starting materials,the final reaction temperature and the amount of additional pentaerythritol were investigated and optimized.The conversion of acetaldehyde reached 100% and the selectivities to pentaerythritol and dipentaerythritol were 91.2% and 4.7%,respectively,while the final reaction temperature was 46 ℃,the n(formaldehyde):n(acetaldehyde):n(NaOH) was 6.0∶1.0∶1.2,and mass fraction 6% of additional pentaerythritol was added. |
