PROCESS FOR THE PREPARATION OF A MIXTURE OF AN ALDEHYDE WITH THE CORRESPONDING ALCOHOL |
摘要 |
<p>The inventive method is particularly advantageous for the preparation of an unsaturated alcohol or aldehyde by the reduction of a corresponding unsaturated carboxylic acid since the unsaturated double bond in the starting acid is not hydrogenated by the reaction of reduction. The method comprises first reacting the starting acid with an alkyl chloroformate to form an intermediate compound by the dehydrochlorination and the intermediate compound is then reduced by using sodium borohydride as the reducing agent. The proportion of the aldehyde to alcohol in the product mixture can be controlled by modifying the amount of the reducing agent and/or the reaction time.</p> |
