| 英文摘要: |
| 1,2-epoxyhexane is an organic chemical intermediate with high added value and widely used in the preparation of polyether polyols, nonionic surfactants and demulsifiers. Reaction mechanism, advantages and disadvantages of the synthesis of 1,2-epoxyhexane from 1-hexene in different oxidation systems were compared. The progress in different catalytic systems for the epoxidation of 1-hexene, including titanium silicalite molecular sieves, metal complexes, polyoxometalates, metal oxides, photocatalysts, biocatalysts and so on, was mainly reviewed. Epoxidation of 1-hexene with hydrogen peroxide or alkyl peroxide is the most environmentally friendly route and is considered to have prospect towards industrialization. The development of efficient and stable catalysts is the focus of future research. |
