Storage stabilized 1,2-dichloroethylene compositions |
摘要 |
Describes a stabilized trans-1,2-dichloroethylene composition having a low concentration of aliphatic aldehyde hydrazone, optionally in combination with an epoxide. The aliphatic aldehyde hydrazone was found to be more efficient than commercially used hydroquinone monomethylether (HQMME) in preventing the isomeric transformation of trans-1,2-dichloroethylene to cis-1,2-dichloroethylene during storage. Also described is a process for cleaning the surface of an article with the stabilized 1,2-dichloroethylene composition.
