| titleOfInvention | Stabilization of halogenated aliphatic hydrocarbons |
| abstract | Halogenated aliphatic hydrocarbons, e.g. trichlorethylene, perchlorethylene, dichlorethylene and vinylidene chloride, which may be used for cyclic degreasing and cleaning processes are stabilized against photo-oxidation by adding at least one ketimine or imino-ethane of general formula <FORM:1023382/C4-C5/1> in which each of R1, R2 and R3 represents an alkyl, alkenyl, alkoxy or alkenoxy group, each group containing less than 8 carbon atoms and being unsubstituted or halogen substituted, e.g. fluorine substituted, or in which R3 represents a hydrogen atom and R1 and R2 are as defined. The groups R1, R2 and R3 may have a conjugated double bond with one of the imine function, or the group R3 linked to the N atom of the imine may be a branched chain group. Compounds specified are 1-ethoxy ethanimine, 1-ethoxy propanimine, 1-n-propoxy ethanimine, N-isopropyl 2-propanimine, N-isobutyl 2-propanimine, N-methyl-2-butanimine and N-propyl-2-butanimine. Other stabilizers such as phenols, esters, aliphatic alcohols and a -epoxy compounds may also be present.ALSO:Stabilizers for halogenated aliphatic hydrocarbons, e.g trichlorethylene, perchlorethylene, dichlorethylenes and vinyl dene chloride comprise at least one ketimine or imino-ether of general formula: <FORM:1023382/C2/1> in which each of R1, R2 and R3 represents an alkyl, alkenyl, alkoxy or alkenoxy group, each group containing less than 8 carbon atoms and being unsubstituted or halogen substituted, e.g. fluorine substituted, or in which R3 represents a hydrogen atom and R1 and R2 are as defined. The groups R1, R2 and R3 may have a conjugated double bond with one of the imine functions, or the group R3 linked to the N atom of the imine may be a branched chain group.

Other stabilizers such as phenols, esters, aliphatic alcohols and a -epoxy compounds may also be present. |
