【摘要】 本实验研究了一种新颖且环境友好的β-甲基萘醌的合成方法。该方法以冰醋酸为溶剂,OP-10为乳化剂,过氧化氢作为氧化剂,氧化β-甲基萘制取β-甲基萘醌。分别考察了反应温度、反应时间、β-甲基萘与冰醋酸摩尔比等因素对β-甲基萘醌转化率和收率的影响。从而得到较优反应条件为:反应温度100℃;反应时间4h;n(β-甲基萘):n(冰醋酸)为1:16;n(β-甲基萘):n(H2O2)为1:11;OP-10用量0.05ml/g(β-MN)。在此条件下,β-甲基萘醌的转化率可达96%,收率可达52%。更多还原

【Abstract】 This paper study a novel and environmentally synthesis route for β-methylnaphthoquinone. Synthesis of β-methylnaphthoquinone with OP-10 as the emulsifier in the acetic-H2O2 system by oxidation of β-methylnaphthalene was researched. The effects of reaction temperature, reaction time, molar ratio of β-methylnaphthalene to glacial acetic acid and molar ratio of β-methylnaphthalene to Hydrogen peroxide on β-methylnaphthoquinone conversion and yield were investigated.The optimal reaction conditions were that reaction temperature was 100 ℃, reaction time 4h, molar ratio of β-methylnaphthalene to acetic acid 1:16 ,molar ratio of β-methylnaphthalene to Hydrogen peroxide 1:11 and OP-10 0.05ml/g(β-MN). In these conditions, β-methylnaphthalene conversion was 96%, the yield of β-methyl-naphthoquinone was above 52% .更多还原
