Sodium Acetate → HCID 225284, compound

Participants

Reaction Steps

To a 100 milliliter round-bottomed flask equipped with a magnetic stirrer and a reflux condenser capped with a paraffin-sealed gas bubbler was added 9.45 grams (0.022 mole) of 1,1-bis(3,5-di-t-butyl-4-hydroxyphenyl)-2-chloroethane (from EXAMPLE 10 above), 20 milliliters of glacial acetic acid, and 2.0 grams (0.024 mole) of anhydrous sodium acetate. The mixture was stirred and heated to reflux for 4 hours. The resulting homogeneous solution was cooled to ambient temperatures to induce crystallization of the product. The precipitated solid material was collected by suction filtration, washed successively with acetic acid and water, and dried to yield 7.8 grams (90 percent) of 3,5,3',5'-tetra-t-butyl-4,4'-dihydroxystilbene, which identity was confirmed by nuclear magnetic resonance spectroscopy.
