【摘要】 研究了以廉价异戊醇为原料合成2,3-戊二酮的新工艺,把异戊醇气体、空气、水蒸汽均匀混合后通过装有催化剂层的固定床反应器,快速进行氧化和分子重排反应。实验结果表明单程反应收率为38%,单程转化率在61%,精馏后的产品纯度在98%以上。该合成方法具有工艺路线短、设备投资小、生产成本低的优势。更多还原

【Abstract】 A novel technology synthesizing 2,3-pentanedione from isoamyl alcohol has been researched, wherein the mixture of isoamyl alcohol, air, steam passed a fixed bed catalytic reactor, and proceeded with oxidation and rearrangement reaction rapidly. Experimental results showed that the yield was 38%, the fractional conversion was 61%, and the purity after rectification was reached above 98%, and this method had the advantages of more simple step, less investment and lower cost.更多还原
