METHOD FOR PRODUCING ALPHA,BETA-UNSATURATED ETHER |
| 摘要 |
<p>Disclosed is a method for producing an ±,²-unsaturated ether efficiently and stably for a long time. In the method for producing an ±,²-unsaturated ether, an acetal is thermally decomposed in the presence of a catalyst containing an apatite represented by any of the following formulae (1)-(4).
€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ(M) 5-y (HZO 4 ) y (ZO 4 ) 3-y (X) 1-y €ƒ€ƒ€ƒ€ƒ€ƒ(1)
€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ(M) 5-y (HPO 4 ) y (PO 4 ) 3-y (X) 1-y €ƒ€ƒ€ƒ€ƒ€ƒ(2)
