  • 上游原料:碳酸钾 --> 二氧化碳 --> 间苯二酚 --> 2,4-二羟基苯甲酸
  • 方法一:其制备方法是将间苯二酚溶于乙醇，在该溶液中加入无水碳酸钾，加热到140℃，通入二氧化碳(二氧化碳气压1400kPa)反应4h，得到2，6-二羟基苯甲酸和2，4-二羟基苯甲酸的混合物(63.1％2，6-二羟基苯甲酸，36.9％2，4-二羟基苯甲酸)，加入水，再加入硫酸调节混合物溶液pH＝6，然后蒸去部分乙醇和水的混合物，残余物在98～100℃回流3h，分解2，4-二羟基苯甲酸。当进行分解反应时，反应混合物的pH值维持在6，适当加硫酸调节pH值。当分解反应完全时，再在混合物中加入硫酸使pH值达到3，有不溶物形成，进行过滤分离，再继续在滤液中加入硫酸使pH值达到1，冷却至5℃，形成2，6-二羟基苯甲酸的结晶，过滤，结晶，用水洗涤，在70℃干燥，得成品。
  • 能还原热的斐林氏溶液，而不还原热的多伦试剂(Tollen's)。遇三氯化铁呈紫至蓝色。溶于乙醇、乙醚和热水。由水中析出者含一分子结晶水，熔点150-170℃，按加热速度而变动，并分解成间苯二酚。有刺激性。
