| 摘 要： | 研究了以乙酰乙酸乙酯为原料合成脱氢醋酸过程中，催化剂的种类、用量以及反应时间对产物得率的影响。结果表明，当采用碳酸氢钠为催化剂，反应物中催化剂的质量分数为0.2%，反应时间为4h，产物得率最高，达82.4%。对所合成的产物通过IR、^1HNMR、^13CNMR和MS分析，表征了其分子结构。

| Abstract: | Dehydroacetic acid was synthesized from acetacetic ether, and the influent factors of productive rate were investigated.The results indicated that the amount of catalyst(Na 2CO 3 ) was 0.2 g(weight of acetacetic ether was 100 g),and reaction time was 4 hours,the maximum yield of dehydroacetic acid was 82.4%.The structure of dehydroacetic acid was confirmed by IR, 1 HNMR, 13 CNMR and MS. |
