  • Dichlorobutene isomerization process
    Patent number: 4827059
    Abstract: Formation of solid and/or high boiling residues during the isomerization of one of 1,4-dichlorobutene-2 and 3,4-dichlorobutene-1 into each other in the presence of a cuprous chloride catalyst is inhibited by the addition to the isomerization reaction of a small amount of a hydroxylamine salt.

  • Stabilized methylchloroform
    Patent number: 4351973
    Abstract: A stabilized methylchloroform for use in vapor degreasing which is stable in the presence of metals which contains pyrazine, dimethoxypropane, an acetylenic alcohol and a nitroalkane or a methylfuran. Such combination prevents corrosion of aluminum, iron, copper and zinc and the decomposition of the solvent.
