| abstract |
The invention relates to a method for the production of isopropenyl ethers of formula (A), wherein R represents an aliphatic, cycloaliphatic, aralyphatic, aromatic or heterocyclic radical which can include other substituents which do not react with acetylenes or allens, by reacting a gaseous flow (I), containing MAPD which is obtained from an olefin system and which is used to separate C3-sections, with at least one gaseous flow selected from a gaseous flow (II) containing an acetone ketal of formula (B), wherein R has the above-mentioned meaning, and a gaseous flow (III) containing a monohydroxyalcohol ROH, wherein R has the above-mentioned meaning, in the presence of a heterogeneous catalyst. |
