| 摘 要： | 以糠醛为初始原料经过制取2-甲基呋喃、2-甲基-2,5-二甲氧基-5-二氢呋喃、2-甲基-3-乙酰硫基呋喃等步骤,合成了2-甲基-3-呋喃硫醇。考察了合成工艺条件对产物收率的影响,确定了最佳合成工艺条件:n(2-甲基-3-乙酰硫基呋喃)∶n(NaOH)∶n(NaH2PO4)=1.00∶0.51∶0.99,乙酸加入量3 mL,反应温度95°C,反应时间20 min,在5.90 kPa下收集57~59.5°C的馏分,在此条件下,收率可达83%。

| Abstract: | From furfural 2-methyl furan,2-methyl-2,5-dimethoxy-5-dihydrofuran and 2-methyl-3-mercapto furan were prepared,and the ultimate product was 2-methyl3-furanethiol.The effect of reaction conditions was investigated.The optimum synthesis conditions were: n(2-methyl-3-mercapto furan)∶n(NaOH)∶n(NaH_2PO_4)=1.00∶0.51∶0.99,acetic acid 3 mL,reaction temperature 95°C and reaction time 20 min.The product was collected at 5.90 kPa and 57～59.5°C.The yield of product reached 83%. |
