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.

Extraction of aromatics with ethyl acetoacetate

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.

Extraction of aromatics with N-cyclohexyl-2-pyrrolidone

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.
