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.
