Synthesis method

2. Introduction to production methods

Will2gChalcones are soluble in120mlEthanol, heated to boiling, mixed with hydrochloric acid and refluxed24h. The residue is filtered off while hot, and the filtrate is cooled and crystallized to obtain flavanones. Then add bromine–Add flavanones to the carbon disulfide solution , benzoflavonoids are produced.
