3,5-Dihydroxybenzyl alcohol Use and Manufacturing
The reaction should be carried out under nitrogen, keeping the reaction system as dry as possible.5 g of sodium borohydride (132 mmol)And 54.5 gEthylene glycol dimethyl ether was added to the reactor, and stirred to uniformly disperse sodium borohydride in the ethylene glycol dimethyl ether solution.(44 mmol) of 3, 5-dihydroxybenzoic acid was dissolved in 34 g of ethylene glycol dimethyl ether solution, This was slowly added dropwise to a solution of sodium borohydride in ethylene glycol dimethyl ether (dropwise over an hour)Keep the temperature between 25 - 30 ° C. After completion of the dropwise addition, stirring was continued at room temperature for 1.5 hours.then, To the reaction system, 25 g (172 mmol) of boron trifluoride diethyl ether solution was added dropwise slowly, It was also added for approximately one hour and maintained at a temperature between 25 and 30 ° C.After completion of the dropwise addition, the reaction was carried out at room temperature for 6 hours. then, The temperature was raised to 35 ° C. 44.3 g of n-butanol was added to the reaction mixture. After stirring for half an hour, the temperature was lowered and the mixture was filtered. The filtrate was removed under reduced pressure at 70/30 mmHg to give 5.3 g of product in about 84percent yield. This product was used in the next step without further purification.
3,5-Dihydroxybenzyl Alcohol is a used as a dendrimer building block.
