Patent ID: 7390777

Claim:
A non-azeotropic solvent composition consisting essentially of trans 1,2-dichloroethylene and an effective stabilizing amount of each of: a. alkylene oxide having from 3 to 12 carbon atoms and a vicinal epoxy group, b. alcohol chosen from aliphatic and cycloaliphatic alcohols having from 2 to 8 carbon atoms, and c. material chosen from (i) lower alkoxyphenol, (ii) free radical stabilizer having at least one 2,2,6,6-tetra(lower alkyl)-1-piperidinyloxy-yl group or 2,2,5,5-tetra(lower alkyl)pyrrolidinyloxy group, or (iii) mixtures of (i) and (ii), wherein the trans 1,2-dichloroethylene is the primary solvent-providing halohydrocarbon of the solvent composition.
