Definitions

  • the present invention relates to liquefied petroleum gas which is a mixture of propane and butanes that can be liquefied under relatively low pressure and at ambient temperature.
  • liquefied petroleum gas is for example used as lighter fuel and as aerosol propellant.
  • the present invention relates in particular to deterring ingestion of liquefied petroleum gas by denaturating the liquefied petroleum gas.
  • the liquefied petroleum gas composition according to the present invention comprises liquefied petroleum gas and a denaturant composition comprising denatonium benzoate dissolved in a low molecular weight alcohol.
  • Denatonium benzoate the most bitter substance known to man, is a well known denaturant which is commercially available from McFarlan Smith Limited under the name Bitrex and is used in alcohol fuel (JP-02-127 496).
  • the present invention is based on the finding that the denatonium benzoate is insoluble in liquefied petroleum gas because it is a polar substance. Applicant had found, however, that a composition comprising denatonium benzoate dissolved in a low molecular weight alcohol is soluble in liquefied petroleum gas.
  • the term 'low molecular weight alcohol' is used to refer to an alcohol having an alkyl group with between 1 and 5 carbon atoms, and suitably between 1 and 3 carbon atoms.
  • Suitable low molecular weight alcohols are methanol and isopropyl alcohol.
  • the concentration of denatonium benzoate in the low molecular weight alcohol should not exceed 1 %m, and suitably the concentration is between 0.5 and 1 %m.
  • the concentration of the denaturant composition in the liquefied petroleum gas composition suitably is not more than 1 000 ppmm, and more suitably between 500 and 1 000 ppmm.
  • the concentration of denatonium benzoate in the low molecular weight alcohol is between 0.5 and 1 %m and the concentration of the denaturant composition is not more than 1 000 ppmm.
  • the concentration of denatonium benzoate in the low molecular alcohol is expressed in %m, for example 1 %m corresponds to 1 g denatonium benzoate in 100 g alcohol.
  • the concentration of denaturant composition in the liquefied petroleum gas composition is expressed in ppmm (parts per million based on mass), for example 1 000 ppmm of denaturant composition corresponds to 1 g of denaturant composition per kg of liquefied petroleum gas.
  • composition A Composition B [DB] in MeOH 1%m 2 %m [DC] in LPG 1 000 ppmm 500 ppmm [DB] in LPG 10 ppmm 10 ppmm Result stable solution unstable solution
  • composition A remained stable for 48 hours under more stringent temperature conditions between -20 and +40 °C.
  • the denaturant composition of the present invention is soluble in liquefied petroleum gas, and that a stable solution can be prepared if the denaturant composition contains between 0.5 and 1 %m of denatonium benzoate.
