  • Extraction of aromatics with ethyl acetoacetate
    Patent number: 4594148
    Abstract: This invention relates to an energy efficient process for the solvent extraction of aromatic hydrocarbons from hydrocarbon streams containing the same, using as the solvent ethyl acetoacetate. This solvent may be recovered from the aromatics by cooling the aromatic/solvent mixture, whereby separation takes place without distillation.
    Type: Grant
    Filed: February 13, 1985
    Date of Patent: June 10, 1986
    Assignee: Sun Refining and Marketing Company
    Inventor: Peter Hosler
  • Extraction of aromatics with N-cyclohexyl-2-pyrrolidone
    Patent number: 4569755
    Abstract: This invention relates to a low energy process for the solvent extraction of aromatic hydrocarbons from hydrocarbon streams containing the same, using as the solvent N-cyclohexyl-2-pyrrolidone together with small amounts of water. This solvent may be recovered from the aromatics by cooling the aromatic/solvent mixture, and adding water, whereby separation takes place without distillation. The solvent may then be separated from the water by heating the solvent/water mixture.

  • 8-Methoxy-p-menthane
    Patent number: 4338469
    Abstract: In the acid-catalyzed etherification of olefins with alcohols, substantially complete recovery of alcohol and catalyst is obtained when small amounts of water (1-10%) are added to the reaction. The addition of water provides a two-phase reaction medium in which olefin and ether are in the upper phase and alcohol and catalyst are in the lower phase. These phase are maintained during the course of the reaction, which continues as a two-phase system.Certain novel ethers produced by this process are likewise disclosed herein.
    Type: Grant
