| titleOfInvention | Process for the preparation of vinyl ethers |
| abstract | The application relates to a process for the preparation of vinyl ethers of the formula in which R¹ to R³ are the same or different from one another and for hydrogen, straight-chain or branched alkyl or alkenyl radicals having up to 12 carbon atoms, cycloalkyl or cycloalkylene radicals having 5 to 8 carbon atoms, aryl, alkylaryl, alkenylaryl, aralkyl and aralkenyl radicals with 6 to 16 carbon atoms, halogen-substituted aryl radicals or for heterocyclic radicals and in addition the radicals R¹ and R² or R¹ and R³ together with the carbon atom to which they are attached can form a cycloalkane, cycloalkene or a heterocycle, and R⁴ represents alkyl or alkylaryl or aralkyl radicals, in which alcohols of acetals / ketals of the formula in the R¹ to R⁴ have the above meaning, in the presence of phosphates with a zeolite structure and / or precipitated phosphates of the elements B, Zr, Ce, Fe and / or phosphoric acid or boric acid on support material and / or acidic undoped metal oxides as catalysts.n n n The reaction is preferably carried out in the gas phase. |
