标题:Synthesis of cyclic trithiocarbonates from epoxides
发明人：PARKER DANE KENTON
权利人:GOODYEAR TIRE & RUBBER
摘要:This invention provides a low cost technique for synthesizing cyclic trithiocarbonates by a simple one step process from epoxides that can be conducted under atmospheric pressure. This synthesis can be depicted as follows: n nwherein R represents a moiety selected from the group consisting of alkyl groups and aryl groups, wherein R′ represents a moiety selected from the group consisting of alkyl groups, aryl groups, and hydrogen atoms, and wherein R″ represents a moiety selected from the group consisting of alkyl groups, aryl groups, and hydrogen atoms, wherein the R moiety and the R′ moiety can be bonded together to form a cyclic structure, with the proviso that R″ represents a hydrogen atom if R′ represents an alkyl group or an aryl group. In this process carbon disulfide and a thiocyanate salt, such as potassium thiocyanate, are reacted with the epoxide in an ionic liquid, such as 1-butyl-3-methylimidazolium hexafluorophosphate ([Bmim] PF 6 ) in the presence of water to produce the cyclic trithiocarbonate.

摘要:The present invention is directed at mono-, di- or polyquaternary ammonium compounds of the formula (I) wherein x is 1 to 50, and F can be the same or different and is represented by the general formula (II) wherein at least one of the optionally substituted and optionally functional-group-containing hydrocarbon radicals R 1 , R 2 , R 3 , R 4 or R 5 contains at least one estolide moiety comprising two or more ester or amide moieties. The invention also relates to a process for the synthesis of such compounds, the use of the compounds in cosmetic formulations for skin and hair care, cosmetic compositions for the treatment of fibers, and compositions containing one or more of the compounds for the treatment of hair.

摘要:The invention is the synthesis and use of epoxidized lignin (EL) preferably with but also without colloidal lignin nanoparticles (CLP, plural CLPs). The invention is divided in two parts, synthesis and utilization. The synthesis of the invention is performed in the following general steps: Preparation of an aqueous solution of lignin and a base. Combining the lignin solution with epichlorohydrin at 1 - 90 °C, where the amount of epichlorohydrin should be within 1 - 20 ml per gram of lignin. Allowing the epoxidation reaction to take place between 1 minutes to 5 hours, while stirring the mixture. Removal of excess epichlorohydrin from epoxidized lignin solution by e.g. solvent extraction. Separation of EL from the aqueous solution. EL functions as a cross-linker and may be used e.g. to prepare adhesives, surface coatings, and composite materials. EL may also be used as foaming agent in water-based solutions.

标 题 :Chloroquine drug compositions and methods for their synthesis
发明人：KOSAK KENNETH M
权利人:KOSAK KENNETH M
摘要:This invention discloses compositions of chloroquine-coupled active agents, including methods for their preparation. The prior art has shown that chloroquines given as free drug in high enough concentration, enhances the release of various agents from cellular endosomes into the cytoplasm. The purpose of these compositions is to provide a controlled amount of chloroquine at the same site where the active agent is delivered, thereby reducing the overall dosage needed. n The compositions comprise a chloroquine substance coupled to an active agent directly or through a variety of pharmaceutical carrier substances. The carrier substances include polysaccharides, synthetic polymers, proteins, micelles and other substances for carrying and releasing the chloroquine compositions in the body for therapeutic effect. The compositions can also include a biocleavable linkage for carrying and releasing active agents for therapeutic or other medical uses. The invention also discloses carrier compositions that are coupled to targeting molecules for targeting the delivery of chloroquine substances and active agents to their site of action.
