摘要
A stabilized azeotrope or azeotrope-like composition is disclosed comprising an azeotrope or azeotrope-like composition of 1,1,2- trichloro- 1,2,2-trifluoroethane, methanol and 1,2-dichloroethylene and about 0.001 to 0.004 wt. percent of a lower alkoxyphenol, about 0.01 to 1. 0 wt. percent 1,2-butylene oxide, about 0.01 to 1.0 wt. percent diisopropylamine and at least one of about 0.01 to 1.0 wt. percent nitromethane and about 0.01 to 1.0 wt. percent 1,2-propylene oxide, said wt. percents based on the weight of the azeotrope or azeotrope-like composition.
