Process for the preparation of trioxane |
| 摘要 |
In a process for the preparation of trioxane from formaldehyde in the gas phase in the presence of a catalyst, the catalyst employed is 11-molybdo-1-vanadophosphoric acid, H4PVMo11O40xn H2O (n=0-32). Advantages of this process are, inter alia, high space-time yields and the suppression of byproducts.
