PROCEDURE

实验过程

4-Aminobutyric acid (50 gm), phosphorous acid (140 gm) and n-octane (1000 mL) was taken in a four necked round bottom flask fitted with an addition funnel, mechanical stirrer, condenser and thermometer pocket and allowed to stir at 90-95° C. Phosphorus trichloride (240 gm) was then added to the reaction mixture and allowed to heat at 90-95° C. The reaction mixture was cooled and distilled water (500 mL) was added to it. The reaction mixture was further heated to 90-95° C. It was then cooled and ethanol (1000 mL) was added to it. The solution was further cooled to 0-5° C. and stirred for 4-5 hrs. The precipitated solid was filtered and washed with ethanol and dried under vacuum to yield 52.0 gm product.
