| titleOfInvention | Unsaturated acetal preparation method |
| abstract | The present invention discloses an unsaturated acetal preparation method. According to the preparation method, an unsaturated alcohol and an unsaturated aldehyde are subjected to a reaction in a pre-reactor to achieve a thermodynamic equilibrium, and then enter a tower type reactor, a water carrying agent is subjected to gasification through a gas generator, and then is subjected to reverse contact with a reaction liquid, and the water generated from the reaction is removed, such that the unsaturated alcohol and the unsaturated aldehyde are subjected to a continuous condensation reaction to prepare the unsaturated acetal. The preparation method has the following characteristics that: the method can be performed under a normal pressure condition, the reaction temperature is constant, low cost synthesis of the unsaturated acetal can be achieved, particularly 3-methyl-2-buten-1-ol and 3-methyl-2-butenal can be adopted as raw materials to synthesize 3-methyl-2-butenal-1 diisopentenyl acetal, wherein the compound is an important intermediate of a synthetic perfume citral. |
