3,6-Dichlorosalicylic acid Use and Manufacturing
The preparation method is to prepare sodium phenolate solution from 2, 5-dichlorophenol and liquid caustic soda, dry in vacuum, then cool the kettle to 100°C, and slowly introduce dry carbon dioxide, when the pressure in the kettle reaches 588～686kPa At this time, the introduction of carbon dioxide is stopped to generate phenol carbonate, and molecular rearrangement reaction occurs at 130-140°C to obtain sodium 3, 6-dichloro-2-hydroxybenzoate, which is then dissolved in water, filtered, and acidified to obtain the product.
3,6-dichloro-2-hydroxybenzoic acid is an intermediate of the herbicide dicamba.
Benzoic acid, 3,6-dichloro-2-hydroxy-: ACTIVE
