Source of material
Equimolar amounts of 2,6–di–tert–butylphenol (98%, Aladdin) and paraformaldehyde (>99%, Aladdin) were mixed and stirred at 373 K for 10 h in the presence of base. The solution was cooled to room temperature, which was purified by column chromatography on silica gel (petroleum ether/ethyl acetate = 20/1) to afford the product as a white solid. The crude product was recrystallized from hexane.
Experimental details
All the Friedel pairs were merged [3]. All H atoms were positioned geometrically and treated as riding, with C—H bond lengths constrained to 0.9 Å for phenyl ring H and 0.9 Å for methyl H atoms, and with Uiso(H) = 1.2Ueq(C) for phenyl ring H atom and 1.5Ueq(C) for methyl H atoms and ethyl H atoms.
Discussion
Hindered phenols had been widely used in high polymer compound as antioxidant [4].
There are two crystallographically independent molecules in the asymmetric unit (cf. the figure). Geometric parameters are in the expected ranges.
In the crystal stucture, the crystal packing is stabilized in layers and held together by van der Waals interactions and classical intermolecular O—H⋯O hydrogen bonds and intramolecular O—H⋯O hydrogen bonds.
