Corrosivity
Corrodes iron and other metals at elevated temperatures when in contact with water.;Will not corrode metals;Iron and zinc do not corrode when dry 1,2-dichloroethane is used, whereas aluminum shows strong dissolution. Increased water content leads to increased corrosion of iron and zinc; aluminum, however, corrodes less.
