High-pressure infrared spectra of 1,4-benzoquinone and tetrafluoro-1,4-benzoquinone
Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, 1996Abstract The pressure dependence of the infrared spectra (600–1800, 2500–3600 cm −1 ) has been measured for 1,4-benzoquinone(2,5-cyclohexadiene-1,4-dione) and fluoranil (2,3,5,6-tetrafluoro-2,5-cyclohexadiene-1,4-dione). No phase changes occur in either compound over the pressure range from ambient pressure to 50 kbar in benzoquinone and to 40 kbar ...

Benzoquinone-based antioxidants
2011The invention relates to a new type of highly polar, at least double-negatively charged redox-active benzoquinones, notably derived from Coenzyme Q0, Q1 and dimethoxy benzoquinones, its production and use. The production of these benzoquinones comprises the reaction of dimethoxy benzoquinones with highly alkaline aqueous solutions. The benzoquinones of
