专利号:US-2018297857-A1 优先权日:2015-06-02 标 题:Aqueous Synthesis of Polyhedral 'Brick-Like' Iron Oxide Nanoparticles for Hyperthermia and T2 MRI Contrast Enhancement, and for Targeting Endothelial Cells for Therapeutic Delivery 发明人:HEGMANN TORSTEN; WORDEN MATTHEW; MILLER DONALD W 权利人:UNIV KENT STATE OHIO 摘要:A low temperature, aqueous synthesis of polyhedral iron oxide nanoparticles (IONPs) is presented. The modification of the co-precipitation hydrolysis method with Triton X surfactants results in the formation of crystalline polyhedral particles. The particles are herein termed iron oxide “nanobricksâ€? (IONBs), as the varieties of particles made are all variations on a simple “brick-likeâ€?, polyhedral shape such as rhombohedral shape or parallelogram as evaluated by TEM. These IONBs can be easily coated with hydrophilic silane ligands, allowing them to be dispersed in aqueous media. The dispersed particles are investigated for potential applications as hyperthermia and T 2 MRI contrast agents. The results demonstrate that the IONBs perform better than comparable spherical IONPs in both applications, and show r 2 values amongst the highest for iron oxide based materials reported in the literature.

专利号:US-6939962-B2 优先权日:2000-07-31 标题:Method for the synthesis of sucrose-6-esters 发明人:CLARK JASON D; LEMAY JR RICHARD R 权利人:TATE & LYLE PLC 摘要:There is described a process for the synthesis of a sucrose-6-ester comprising: (a) reacting a mixture comprising sucrose and a polar aprotic solvent with an organotin-based acylation promoter, while adding a solvent capable of removing water by co-distillation, and removing water by co-distillation, to afford a first reaction mixture which is substantially free from water, followed by (b) adding a carboxylic anhydride to said first reaction mixture to afford a second reaction mixture, and maintaining said second reaction mixture at a temperature and for a period of time sufficient to produce a sucrose-6-ester, characterised in that step (a) is performed at a temperature of from 85 to 125° C. and at a pressure of from 20 to 80 kPa. In the most preferred embodiment, the polar aprotic solvent is DMF, the solvent capable of removing water by co-distillation is cyclohexane, the organotion-based acylation promoter is a 1,3-diacyloxy-1,1,3,3-tetrabutyldistannoxane, and step (a) is performed at approximately 97° C., and approximately 50 kpa, until the weight ratio of tin to water in the first reaction mixture is greater than about 26, when the tin content is measured by X-Ray Fluoresence Analyzer, and the water content is measured by the Karl-Fischer method.
专利号:US-11958751-B2 优先权日:2022-06-27 标 题:Method of synthesizing materials integrating supernatant recycle 发明人:HODGKINS ROBERT P; KOSEOGLU OMER REFA 权利人:SAUDI ARABIAN OIL CO 摘要:Methods are disclosed for synthesizing materials, including an initial synthesis in the presence of WS-ODSO (which can include a pH-modified WS-ODSO composition, in certain embodiments a neutralized WS-ODSO composition), and one or more subsequent syntheses using supernatant (“mother liquorâ€?) from a previous synthesis of the same or different materials. The synthesized materials in the initial synthesis and in subsequent synthesis can be the same or different inorganic oxide materials including amorphous oxides, crystalline oxides or oxides of metals. The methods advantageously reduce the amount of utility water required for synthesizing a material and reduce the water waste, and reduce the DSO waste from a refinery and discharge into the environment. In certain embodiments the methods reduce the requirements to procure an alkaline reagent required for synthesizing materials. In certain embodiments, supernatant can be recycled over multiple synthesis batches of the same or different type of materia.
