摘要
以2-甲萘为原料,冰醋酸为溶剂,H2O2为氧化剂,在浓硫酸的催化下合成2-甲萘醌。所得结果经核磁分析,确定为2-甲萘醌,以标准品为对照,用HPLC检测纯度。实验确定的优化条件为:当2-甲基萘与乙酸的物质的量比为1∶11.5、H2O2与乙酸的物质的量比为1∶1.4、浓硫酸的物质的量为0.045时,75℃下反应5h,2-甲基萘的转化率为81.1%,2-甲萘醌的收率最高可达到55.9%。
In this paper,2-methylnaphthalene was used as raw material,glacial acetic acid as solvent and H2O2 as oxidant to synthesize 2-methylnaphthalene quinone under the catalysis of concentrated sulfuric acid.The measured results were determined as 2-methylnaphthalene quinone by nuclear magnetic analysis,and the purity was tested by HPLC with standard reference.Through the experiment,the optimized experimental conditions were obtained as followed:when the amount of 2-methylnaphthalene and acetic acid was 1:11.5,the ratio of H2O2 to acetic acid was 1:1.4,and the amount of concentrated sulfuric acid was 0.045,the conversion rate of 2-methylnaphthalene was 81.1%and the yield of 2-methylnaphthalene quinone reached 55.9%at 75℃for 5h.
