其他信息

  • 用途一:偶氮染料中间体。
  • MOL 文件:499-76-3.mol
  • 方法一:由邻甲酚经酸甲基化而得。将邻甲酚和50%氢氧化钠水溶液加入反应釜中，用蒸汽处理之后，在160℃以下压入二氧化碳，经蒸馏得粗邻甲酚对甲酸钠，再将其用硫酸中和，精制，最后真空干燥即得成品，收率88%。
  • 上游原料:甲酸钠 --> 邻甲酚 --> 对甲基苯甲酸
  • Sigma Aldrich:499-76-3(sigmaaldrich)
  • Alfa Aesar:4-羟基-3-甲基苯甲酸,97% 4-Hydroxy-3-methylbenzoic acid hydrate, 97%(499-76-3)
