2-萘酚合成路线

详细合成路线

2-萘酚上下游产品

2-萘酚上游产品

2-萘酚下游产品

2-萘酚制备

【方法一】
其制备方法是在140℃将硫酸加入熔融萘中，在162～164℃进行磺化，将磺化物水解，吹去游离萘，用亚硫酸钠与其反应使生成2-萘磺酸钠盐，该钠盐固体和氢氧化钠于285～320℃进行碱熔，然后在320～330℃保温1h，将碱熔物稀释后通入二氧化硫进行酸化得粗制品，洗涤脱水后蒸馏而得产品。
【方法二】
磺化碱熔法
将精萘置于磺化锅，加热(熔融)至140℃。在20min内加入1.085倍(摩尔比)浓硫酸，升温，并在160～164℃下保温2.5h。当2-萘磺酸含量达66%以上、总酸度为25%～27%时结束反应。磺化物于水解锅中在140～150℃下水解1h。然后在中和锅中，在80~90℃下用亚硫酸氢钠溶液中和至刚果红试纸不变蓝为止。用蒸汽和空气驱除SO2气体，降温至30～40℃后吸滤，并用10%的食盐水洗涤后再吸滤得2-萘磺酸钠。
将氢氧化钠置于碱熔锅中，加热(熔融)至290℃，在约3h内将2-萘磺酸钠加入，直至游离碱含量为5%～6%为止。之后，于320～330℃下保温1h。碱熔物稀释于水中，在70~80℃下通SO2至酚酞无色。加水煮洗，除去亚硫酸钠，再经脱水、减压蒸馏得成品，总收率为73%～74%。
2-异丙萘法
以萘和丙烯为原料，在生产2-萘酚的同时副产丙酮。
【方法三】
（1）磺化碱熔法。将精萘置于磺化锅，加热（熔融）至140℃。在20min内加入1.085倍(摩尔比)浓硫酸，升温，并在160-164℃下保温2.5h。当2-萘磺酸含量达66%以上、总酸度为25%-27%时结束反应。磺化物于水解锅中在140-150℃下水解1h。然后在中和锅中，在80-90℃下用亚硝酸氢钠溶液中和至刚果红试纸不变蓝为止。用蒸汽和空气驱除SO2气体，降温至30-40℃后吸滤，并用10%的食盐水洗涤后再吸滤得2-萘磺酸钠。
将氢氧化钠置于碱熔锅中，加热（熔融）至290℃，在约3h内将2-萘磺酸钠加入，直至游离碱含量为5%-6%为止。之后于320-330℃下保温1h。碱熔物稀释于水中，在70-80℃下通SO2至酚酞无色。加水煮洗，除去亚硫酸钠，再经脱水、减压蒸馏得成品，总收率为73%-74%.。
（2）2-异丙萘法。以萘和丙烯为原料，再生产2-萘酚的同时副产丙酮。
【方法四】
由萘经磺化、碱熔制得。磺化碱熔法是国内外广泛采用的生产方法，但腐蚀严重，成本较高，废水生物氧耗量高。美国氰胺公司开发的2-异丙萘法，以萘和丙烯为原料，在生产2-萘酚的同时副产丙酮，这方法与异丙苯法制苯酚的情况类似。原料消耗定额：精萘1170kg/t、硫酸1080kg/t、固体烧碱700kg/t。
