Yield:18916-17-1 98%
Reaction Conditions:
with palladium on activated charcoal;hydrogen;potassium hydroxide in ethanol at 55; under 7500.75 - 15001.5 Torr;Autoclave;Temperature;Reagent/catalyst;Pressure;
Steps:
4
Natural extract 120g 600g8% naringin was dissolved in a solution of potassiumhydroxide, clear solution was filtered, and the filtrate was added 2000ml autoclave,200g of ethanol was added, 3g palladium on carbon catalyst, 55 introducing hydrogenat a pressure of 1 ~ 2MPa , 5 ~ 7H after hydrogen absorption substantially completehydrogen absorption, the reaction solution was taken out, filtered off and palladium oncarbon, hydrogenation was directly acidified with hydrochloric acid to adjust pH to 5-7,stirred sufficiently crystallized white solid precipitated quickly. Cooling to 20 filtration, the wet product was dried under reduced pressure at 60 , you can getdihydro naringin chalcone 118g, white powder, liquid purity 98.9% molar yield of 98%.Products from light nitrogen stored in a cool place.
