Verfahren zur Herstellung von 3-Oxyalkylpropan-1-olen |
| 摘要 |
The preparation of a 3-alkoxy-propan-1-ol of formula (I) comprises catalytic hydrogenation of a 1,3-dioxane of formula (II) at 0.1-35 MPa and 40-500 degrees C. The catalyst has an acidic support and one or more group VIB, IIB and/or IB metal other than chromium and nickel as hydrogenation-active component. R1, R2, R4, R5 = H, or 1-18C alkyl, 2-18C alkenyl, 2-18C alkynyl, 5-8 C cycloalkyl, 5-8 C cycloalkenyl, 6-16 C aryl, alkylaryl, aralkyl, alkenylaryl, aralkenyl or heterocyclyl (all optionally substituted); or CR1R2, CR4R5 = cycloalkane, cycloalkene or heterocycle with 5-7 ring members (all optionally substituted); R3 = H or alkyl. |
