    Abstract: The present invention relates to solvent compositions and processes for inhibiting the generation of peroxide in glycol ether solvents. In one aspect, a solvent composition comprises at least one glycol ether, at least one antioxidant, wherein the at least one antioxidant is selected from the group consisting of L-ascorbic acid-6-hexadecanoate, pentaerythritol tetrakis(3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate), and mixtures thereof, wherein the amount of the antioxidant in the solvent composition is less than or equal to 1,000 ppm by weight based on the total weight of the solvent composition and a peroxide, wherein the amount of the peroxide in the solvent composition is less than 20 ppm, based on the total weight of the solvent composition.

    Abstract: A solvent composition and system is disclosed having a composition including n-propyl bromide and a propionate containing liquid and/or a butyrate containing liquid. The solvent system may include approximately 35 to 92.5 weight percent propionate containing liquid and approximately 7.5 to 65 weight percent n-propyl bromide. Alternatively, the solvent system may include approximately 40 to 85 weight percent butyrate containing liquid and 15 to 60 weight percent, n-propyl bromide. The solvent system may incorporate a polymer, such as a synthetic rubber polymer. Further the solvent system preferably has high solvency while maintaining desirable evaporation rates and is preferably nonflammable, combustible, or minimally a class IC flammable liquid.
