Method for the production of unsaturated ethers |
| abstract |
The present invention relates to a process for the preparation of ethers of the formula R¹-CR² = CH-O-R³, wherein R¹ and R³ each represent a radical having 1 to 6 carbon atoms and R² is hydrogen or a radical having 1 to 2 carbon atoms Reaction of a diacetal of the formula R¹-CHR²-CH (-O-R³) ₂ in the presence of a catalyst consisting of an acid and an amine at elevated temperature in the liquid phase. The unsaturated ether of the above formula is formed from the diacetal with elimination of an alcohol R³-OH. |
