Definitions

  • This invention relates to the stabilization of chlorinated hydrocarbons.
  • Com ounds of this class for example, trichloret ylene, tetrachlorethane or methylene 5 chloride, tend to undergo decomposition during storage with the formation of substances of acid character. This decomposition makes the product objectionable for such purposes as extraction'and produces an acidity that corrodes storage tanks. While this type of decomposition is more or less general in all chlorinated hydrocarbons, it has been found that materials added to 16 and as such may be very satisfactory for the stabilization of one or more compounds but are not necessarily satisfactory for all others.
  • Hydrocarbons for instance gasoline
  • stabilizers for trichlorethylene Hydrocarbons, for instance gasoline, have been proposed as stabilizers for trichlorethylene. These are objectionable when the solvent is used in certain processes because a comparatively large amount of gasoline is 4 required to stabilize and the hydrocarbon heavy ends may be deposited in and contaminate the product.
  • the object of this invention is to provide an efiective stabilizer for chlorinated hydrotb carbons which need be applied only in small Application filed march 8,
  • chlorinated hydrocarbon decomposition with the resultant development of acidity, may be prevented by the addition of amylene in appropriate amounts.
  • My process of stabilization consists in mixing a small amount, for instance, 0.0001- 01%, of the stabilizer with the chlorinated hydrocarbon.
  • a preferred method of mixing consists in transferring the required amount of a strong stock solution of amylene, made up by weight to known concentration in the chlorinated hydrocarbon to be stabilized, into a known volume of that chlorinated hydrocarbon.
  • composition of matter comprising a an chlorinated hydrocarbon and stabilizing amounts of amylene.
  • composition of matter comprising a chlorinated hydrocarbon of the group comprising methylene chloride, trichlorethylene,
  • composition of matter comprising a chlorinated hydrocarbon and from about M 0.0001% to about 1% by weight of amylene.
  • composition of matter comprising methylene chloride and stabilizing amounts ot' amylene.
  • composition of matter comprising methylene chloride and from about 0.0001% to about 1% by weight of amylene.
