Storage method
This product should be sealed and stored in a cool place.
Synthesis method
It is obtained by reducing phenyl acetone with potassium borohydride in ethanol. Add phenylacetone and ethanol into the reaction pot, roll in potassium borohydride in batches while cooling and stirring, add hydrochloric acid dropwise to adjust the pH to 9-9.5, and control the temperature not to exceed 30°C. After the reaction is completed, neutralize it with hydrochloric acid to neutrality, recover ethanol by distillation, cool and separate into layers, separate the water layer and perform vacuum distillation to collect the 108-116°C (2.66kPa) fraction, which is 1-phenylpropanol. The yield is 96%.
Purpose
This product is used as a spice, heat transfer medium, and is also a choleretic. When used as a drug, it is also called cholerol, which can promote bile secretion, facilitate digestion, increase appetite, expel stones, and lower blood cholesterol. Suitable for cholecystitis, biliary tract infection, cholelithiasis, biliary postoperative syndrome, and hypercholesterolemia.
