苯磺酸

【用途一】
用作实验试剂、催化剂，也用于有机合成及苯酚制造
【用途二】
主要用于经碱熔制苯酚，也用于制间苯二酚等，在酯化和脱水反应中常用作催化剂
【用途三】
苯磺酸用于油田注水，可以解除地层的堵塞、提高地层渗透率。作为酸化注水井的酸，苯磺酸的特点是与碳酸盐反应慢，而且浓度愈大，反应速度愈慢，能酸化深远的地层，与盐酸相比，苯磺酸（及混合芳基磺酸）有效期长、腐蚀性小、使用安全。苯磺酸还用做酯化和脱水反应的催化剂和铸造工业的固化剂。
【用途四】
检验铵盐和钾盐。锌的测定。有机合成。制造苯酚、间苯二酚。催化剂。用作脱水催化剂、树脂固化剂，以及电镀添加剂，同时还可以作为染料中间体。主要用于经碱熔制苯酚，也用于制间苯二酚等，在酯化和脱水反应中常用作催化剂

详细合成路线

苯磺酸上游产品

苯磺酸下游产品

以苯为原料，经硫酸磺化而得。将93%硫酸2400L加入磺化锅内，将苯以2500-3000L/h的流量打入蒸发器，经过蒸发及过热成温度为150℃以上的过热苯蒸气，通过鼓泡器在硫酸层中进行反应，温度在170℃左右，最后游离酸控制在4-5%。大约经过10h左右完成反应，未反应的苯蒸气和生成的水蒸气经冷凝分离，酸性苯再经液碱中和、食盐脱水后循环使用。含苯的苯磺酸再经真空脱苯器脱除余苯。磺化收率96.5%。苯磺酸用亚硫酸钠或氢氧化钠中和，即得苯磺酸钠。中和收率99%。原料消耗定额：苯600kg/t、发烟硫酸750kg/t。
