摘要： A method for extracting and separating extractive components from fluids is provided. A first fluid and an extraction fluid are added to a vessel, thereby creating a two-phase two-layer system, wherein the first fluid and the extraction fluid are discrete and the two-phase system has a first fluid/extraction fluid interface. The two-phase system is then agitated, wherein the first fluid phase and the extraction fluid phase remain as substantially discrete layers. A means for communication between the first fluid and the extraction fluid is provided. The communication of the phases results in the extractive components being extracted from the first fluid into the extraction fluid. Agitation is stopped and the first fluid is recovered having reduced extractive components.

摘要： This invention is a process for making a difunctional lithium initiator which comprises reacting a secondary or tertiary lithium alkyl with a diisopropenylbenzene compound in the presence of diethyl ether at a temperature of 25 to 50° C. wherein the molar ratio of the diethyl ether to the lithium alkyl is from above 0.1:1 to 2:1 and the diisopropenylbenzene compound and the diethyl ether are first mixed together and then added to the lithium alkyl. The molar ratio of the diisopropenylbenzene compound to the lithium alkyl should be as close to 0.5:1 as possible. An excess of lithium alkyl may be used if a product containing both diinitiator and monoinitiator is preferred. It is preferred that the molar ratio of diethyl ether to lithium alkyl be as close to 1:1 as possible.
