Polymorphic forms of tetrahydro-N,N-dimethyl-2,2-diphenyl-3 -furanmethanamine hydrochloride (ANAVEX2-73) and a metabolite of tetrahydro-N,N-dimethyl-2,2-diphenyl-3-furanmethanamine hydrochloride (ANAVEX2-73) are disclosed and characterized. Compositions and method for treatment of Alzheimer's disease that includes the polymorphic forms and metabolite of tetrahydro-N,N-dimethyl-2,2 -diphenyl-3-furanmethanamine hydrochloride (ANAVEX2-73).

The present invention provides a portable extraction device for extracting at least one constituent from a substance by an extraction fluid. The extraction device comprises at least one pump, an extractor, an evaporator, and a condenser. The substance and the extraction fluid are placed and mixed in the extractor. The extraction fluid is a subcritical fluid. The constituent in the substance will be dissolved in the extraction fluid under a predetermined pressure and temperature. The evaporator receives the extraction fluid including the constituent from the extractor, and heats the extraction fluid including the constituent to gasify the extraction fluid and separate the constituent from the gasified extraction fluid. The condenser receives the gasified extraction fluid via a first pipe, liquefies the gasified extraction fluid, and transmits the liquefied extraction fluid to the extractor via a second pipe. The extractor, the evaporator, and the condenser are operated under constant pressure.

A method for modifying the composition of essential oils to be used as such or as ingredients for flavour and fragrance formulations, the process using carbon dioxide and suitable solvents in combination with specific supports; Flavours and fragrances containing ingredients produced by the method and applications using the flavours and fragrances.

Embodiments of a process for producing high grade coke from crude oil residue include at least partially separating, in a solvent extraction unit, the crude oil residue into a deasphalted oil (DAO)-containing stream and an asphaltene containing-stream, producing a pressurized, heated DAO-containing stream, where the pressurized, heated DAO-containing stream, mixing a supercritical water stream with the pressurized, heated DAO-containing stream to create a combined feed stream, introducing the combined feed stream to an upgrading reactor system operating at supercritical temperature and pressure to yield one or more upgrading reactor output streams comprising upgraded product and a slurry mixture, where the slurry mixture comprises sulfur and one or more additional metals. The process also may include calcining the slurry mixture at a temperature of from 700 C. to 1900 C. to produce a product stream comprising the high grade coke.

Targetry coupled separation refers to enhancing the production of a predetermined radiation product through the selection of a target (including selection of the target material and the material's physical structure) and separation chemistry in order to optimize the recovery of the predetermined radiation product. This disclosure describes systems and methods for creating (through irradiation) and removing one or more desired radioisotopes from a target and further describes systems and methods that allow the same target to undergo multiple irradiations and separation operations without damage to the target. In contrast with the prior art that requires complete dissolution or destruction of a target before recovery of any irradiation products, the repeated reuse of the same physical target allowed by targetry coupled separation represents a significant increase in efficiency and decrease in cost over the prior art.
