Diamines, useful in the rubber industry as antiozone agents, are similarly produced from aniline: Hydroquinone has a variety of uses principally associated with its action as a reducing agent that is soluble in water. The composition is preferably formulated in separate phases as designated below. Additionally, a water-soluble antioxidant, preferably a sulfite, including but not limited to sulfites, bisulfites, metabisulfites, their salts and their derivatives, most preferably sodium metabisulfite, may be helpful in stabilizing the hydroquinone composition. Antioxidants, preferably sulfites, including but not limited to sulfites, bisulfites, metabisulfites, their salts, and their derivatives, most preferably sodium metabisulfite, have been used to stabilize certain compositions, which have included hydroquinone. 1 Solubility data for compounds that ordinarily are liquids at 25 are expressed in terms of the ratio of the volume of solute to the volume of solvent; i.e., 1 mL dissolved in mL of solvent. 0000002544 00000 n Data 53, 199200 (2008), N.
