preparation example 1
[0023] Preparation Example 1 Preparation of formononetin-3'-sodium sulfonate
[0024] Add 3 kg of formononetin (purchased from Xi'an Yangling Dongke Madison Pharmaceutical Company, batch number 081211, content 98.5%) into the reaction kettle, stir with a mixer and gradually add solvent 80% sulfuric acid until formononetin is fully dissolved, and then Add sulfonating agent 98% concentrated sulfuric acid, and the molar ratio of formononetin to sulfonating agent is 1:5. After stirring with a mixer, use a temperature adjusting device to make the temperature of the reaction solution 60°C and react for 6 hours to obtain formononetia The mixture of Su-3′-sulfonic acid and unreacted raw materials is cooled to room temperature, and a 10% sodium chloride aqueous solution of 5 times the total volume of the reactants is added, fully stirred, and left to stand to precipitate a white precipitate, which is filtered to obtain formononetin -3′-Sodium Sulfonate Crude Product; Use the recrystalliza...
