Abstract: The present invention relates to highly concentrated, anhydrous amine salts of hydrocarbon polyalkoxy sulfates, wherein the salts are selected from the group of substituted amines, preferably alkanolamines. The products obtained are of low viscosity and pumpable at room temperature. Due to the absence of water, the salts are highly resistant to hydrolysis, even at high temperatures. The invention further relates to the use of the compositions according to the invention in an aqueous dilution for use in oil reservoirs with the aim of achieving enhanced oil production, or for the recovery of hydrocarbons from tar sands or other surfaces or materials provided with hydrocarbon.

Abstract: This invention relates to novel methods for facilitating the enzymatic resolution of racemic mixtures of esters, which are derivatized with groups which enhance the esters' aqueous solubility, in an extractive member reactor where the enzyme is placed alternatively either (1) in the aqueous phase, (2) in association with the membrane, or (3) in the aqueous phase and in association with the membrane, wherein the aqueous ester phase is contacted with one side of the membrane, and where an organic extractive phase is contacted with the other side of the membrane, wherein the extractive phase serves to remove the resolving reaction product. Of particular significance regarding this invention is its use of water soluble esters that are derivatized with groups which enhance their aqueous solubility and their reactivity with enzymatic resolving methods which are mediated in an aqueous environment. Novel methods were utilized to prepare these esters, for use in this invention's methods for enzymatically resolving the racemic mixtures of the esters, to produce the separate chiral isomers of the racemic mixture. The importance of the resolution of the separate chiral isomers of the racemic mixtures resides in the isolation of the isomers which frequently have different biological activities.

Abstract: This invention relates to a novel method of effecting aqueous enzymatic and homogeneous resolutions of racemic esters which exhibit enhanced aqueous solubility. The preferred embodiment of this invention relates to the resolutions which are effected by placing the enzyme and racemic esters in an aqueous phase wherein one of the ester enantiomers is preferentially and stereospecifically de-esterified to effect the resolution of the initial racemic mixture. In another embodiment of this invention, the resolutions are effected by placing the enzyme and racemic esters in an aqueous phase, and contacting this aqueous phase with an organic phase. The preferential and stereospecific de-esterification of one of the ester enantiomers is effected, and the chiral acid product of the de-esterification reaction is extracted into the organic phase.
